LTM8047 - Isolated Flyback uModule DC/DC, 32V In | Analog Devices
The Analog Devices LTM8047 is an isolated flyback uModule (power module) DC/DC converter with a 725VDC isolation rating, operating from a 3.1V to 32V input and delivering an output voltage range of 2.5V to 12V at up to 440mA (as listed for the LTM8047MPY on DigiKey), housed in a compact surface-mount BGA/LGA-style module package. An isolated DC/DC converter is a switching power converter in which the input and output share no galvanic connection; energy is transferred across a transformer, breaking ground loops and providing an isolation barrier. Within the power management hierarchy, the LTM8047 belongs to the family of system-in-package power modules (uModules), which integrate a switching controller, power switches, a transformer, and all support components into a single surface-mount device. Key features include the 725VDC isolation rating (tested at 725VDC for one second in each polarity, per the manufacturer datasheet), a wide 3.1V to 32V input range suitable for unregulated industrial and automotive rails, and full integration of the flyback power stage. Because the transformer is built into the package, designers eliminate the most difficult part of isolated-supply design: magnetics selection, layout, and creepage management. The LTM8047 uses a flyback architecture in which the controller drives integrated power switches and a coupled inductor. Output voltage is set with a small number of external resistors, and a soft-start pin (SS) sources approximately 10uA during startup, per the datasheet, enabling controlled power-up. The device is also usable in inverting and SEPIC configurations per manufacturer documentation. Typical applications include isolated bias supplies for industrial PLCs, isolated sensor and transducer interfaces, isolated communication port power (RS-485/CAN bias rails), and negative or SEPIC rail generation where a single small module replaces a discrete transformer-based design. A key design consideration is thermal: as a fully integrated module, power dissipation depends on VIN/VOUT/frequency setting, so copper area under the package ground pads governs junction temperature. Verify output current derating at your operating point in the datasheet thermal curves.

LTM8061IV-8.4#PBF - 32V, 2A Li-Ion Battery Charger µModule | ADI
The Analog Devices LTM8061IV-8.4#PBF is a complete 32V, 2A µModule (power module) standalone Li-Ion/Polymer battery charger optimized for two-cell (8.4V) battery packs, integrating the switching controller, power MOSFETs, inductor, and support components into a single 77-LGA (15mm x 9mm x 4.32mm) over-molded package. It provides fixed 8.4V float voltage, 32V maximum input voltage, and up to 2A programmable charge current, making it a turnkey charging solution for portable and industrial battery-powered systems. A µModule battery charger is a complete switching-mode charger subsystem co-packaged into a single land-grid-array (LGA) module, eliminating the need for discrete power-stage layout. The LTM8061 uses a constant-current/constant-voltage (CC/CV) charge profile, the standard algorithm required by Li-Ion and Li-Polymer cells. As part of the broader power management IC hierarchy (charger IC -> battery management -> PMIC -> semiconductor), it sits between an unregulated DC source (e.g., 5-32V adapter or solar panel) and a 2-cell Li-Ion/Polymer stack. Key features include 32V absolute maximum input voltage, 2A programmable charge current via a single external program resistor, an internal safety timer, auto-restart when battery voltage drops 2.5% below float, NTC input for battery temperature qualification, and a C/10 charge-current termination mode. The µModule construction yields high efficiency, low EMI, and a compact footprint, all critical for space-constrained designs where discrete charger layouts would consume excessive PCB area. The internal architecture combines a current-mode PWM controller, synchronous rectification MOSFETs, an integrated power inductor, and feedback compensation. Built-in input reverse-voltage blocking, output over-voltage protection, and thermal shutdown reduce external component count to just input/output capacitors, program resistor, and the NTC thermistor network. Efficiency peaks above 90% at typical VIN/VOUT ratios due to synchronous rectification. Typical applications include 2-cell Li-Ion/Polymer pack charging in portable medical devices, industrial handheld instruments, two-way radios, power tools, e-bike accessories, and solar-powered IoT sensor nodes. Its 32V VIN tolerance allows direct connection to 12V/24V industrial bus rails or unregulated adapter outputs, removing the need for pre-regulation. When designing with the LTM8061IV-9, allocate at least 1 square inch of PCB copper under the LGA thermal pad to achieve rated 2A charge current; the junction-to-ambient thermal resistance dominates at full power. Use the Analog Devices evaluation board layout as a starting point, and respect the keep-out zone around the LGA package to avoid disturbing the magnetic flux path of the integrated inductor.

LTM8062EV#PBF - 32V 2A Battery Charger Module | Analog Devices
The Analog Devices LTM8062EV#PBF is a complete 32V-input, 2A micro-module (uModule) power tracking battery charger in a 77-pin LGA (15 x 9 mm) surface-mount package, supporting Li-Ion, Li-Polymer, LiFePO4 and SLA (lead-acid) battery chemistries with up to 14.4V float voltage. A battery charger IC is a power-management device that controls charge current, charge voltage and charge termination for rechargeable cells. The LTM8062 sits at the top of the battery management hierarchy (battery charger -> battery management IC -> power management IC) and integrates a complete switching charger system, including the power switch, power inductor and control loop, inside a single LGA package. This system-in-package approach drastically reduces external component count compared to a controller-plus-discrete-FET design. Key features include a wide 4.95V to 32V input range (40V absolute maximum), 2A maximum charge current, and a precision 0.75% float voltage reference. The device accommodates Li-Ion/Polymer, LiFePO4 and SLA batteries, supports up to 5 cells, and includes integrated input reverse-voltage protection. Resistor-programmable float voltage reaches 14.4V on the LTM8062 (18.8V on the LTM8062A variant). Technically, the LTM8062 employs an input supply voltage regulation loop that reduces charge current whenever the input voltage falls below a resistor-programmed threshold. When powered from a solar panel, this loop performs MPPT (maximum peak power tracking), holding the panel at its peak output power point. The charger also provides preconditioning trickle charge and bad battery detection, improving safety and battery lifetime. Typical applications include solar-powered battery charging systems, portable instrumentation, backup power supplies, and industrial equipment using 12V lead-acid or multi-cell Li-Ion packs. The 32V input range comfortably supports 12V to 24V solar panels and industrial DC buses. Design consideration: because the charger dissipates heat inside the 15 x 9 mm LGA substrate, PCB copper area under the package governs the maximum internal junction temperature; the E-grade version is specified over an internal operating range extending to 125C, but thermal derating of charge current is required at high input-to-output differentials.

LTM8074IY#PBF - 40V/1.2A Silent Switcher µModule | Analog Devices
The Analog Devices LTM8074IY#PBF is a 40V input, 1.2A continuous (1.75A peak), step-down µModule (power module) regulator integrating the Silent Switcher architecture to minimize EMI emissions while delivering high efficiency at switching frequencies up to 2.2 MHz. Housed in a thermally enhanced, compact over-molded 25-ball BGA package (4mm x 4mm x 1.25mm profile), the LTM8074IY#PBF includes the switching controller, power switches, inductor, and supporting passive components in a single, surface-mountable module that drops onto the bottom side of a PCB for high-density point-of-load regulation. What is a µModule regulator? A µModule (micromodule) regulator is a complete, factory-assembled DC-DC switching power supply packaged as a single surface-mount IC, integrating the controller IC, power inductor, MOSFET switches, and compensation network inside the package. It sits hierarchically between discrete buck regulators and full isolated brick converters in the power-management-IC taxonomy: discrete buck -> µModule regulator -> isolated PoL -> power management IC -> semiconductor. µModules dramatically shorten design time, reduce PCB footprint, and solve the layout-driven noise and thermal issues that plague discrete buck implementations. Key features include a wide 3.2V to 40V input range, an adjustable 0.8V to 12V output, internal feedback loop compensation, programmable soft-start, and an operating junction temperature range of -40°C to +125°C for industrial-grade deployment. The Silent Switcher topology uses split-parallel internal capacitors to cancel the hot-loop di/dt, allowing the part to pass stringent EMI standards (CISPR 22 Class B, CISPR 25) without complex shielding. Synchronizable to an external clock from 200 kHz to 2.2 MHz avoids beat-frequency interference in multi-rail systems. The Silent Switcher 2 architecture uses integrated ceramic capacitors across the internal hot loop to nearly eliminate radiated EMI, enabling use in noise-sensitive environments like automotive ADAS, industrial sensor arrays, and RF front-end bias supplies. Compared with conventional buck ICs at the same input/output range, the LTM8074IY#PBF's monolithic integration delivers a typical efficiency above 90% at 12V-to-5V/0.5A, with internal current mode control providing line and load regulation across the operating envelope. Typical applications include industrial 24V bus point-of-load conversion, automotive body and ADAS sensor rails, factory automation backplanes, general-purpose 5V/3.3V PoL for FPGA, MCU, and ASIC rails, and low-EMI medical instrumentation power. The over-molded body supports the BGA solder joints against mechanical stress, and the dual-bank GND paddle structure provides both low-impedance return paths and a primary thermal dissipation route. When designing with this device, derate output current for ambient temperature above 85°C and provide sufficient PCB copper area beneath the module's GND banks, which carry most of the heat out of the package. The exposed BGA pads must be soldered to inner-plane copper for thermal spreading; a 1oz copper pour of roughly 1 cm² directly below the module typically limits junction temperature rise to about 20°C at full load. Input bulk capacitance placement near the input balls minimizes reflected input ripple. This page synthesizes distributor pricing, drop-in alternatives, BGA thermal design notes, and Silent Switcher EMI mitigation guidance that go beyond what the manufacturer datasheet presents in isolation.
LV14360 - 60V 3A Step-Down Buck Converter | Texas Instruments
The Texas Instruments LV14360 is a 60-V, 3-A step-down regulator with an integrated high-side MOSFET. It operates from a wide input voltage range of 4.3 V to 60 V, making it suitable for industrial and automotive power conditioning from unregulated sources. The device is available in an 8-pin HSOIC package (4.89 mm x 3.9 mm) with an exposed pad for low thermal resistance. A step-down converter, also known as a buck converter, is a DC-DC switching regulator that efficiently reduces a higher input voltage to a lower output voltage. It is a fundamental building block in power management, converting unregulated or higher-voltage supplies into stable, lower-voltage rails for electronic systems. The LV14360 uses constant frequency peak current mode control with sleep mode at light load to achieve high efficiency, reducing power loss and extending battery life. Key features include a quiescent current of 300 uA in sleep mode, an ultra-low 1-uA shutdown current, and an adjustable output voltage down to 0.8 V. The device is internally compensated, which reduces design time and requires fewer external components. It also features cycle-by-cycle current limiting, thermal shutdown, and a power-good output for system monitoring. The LV14360 implements constant frequency peak current mode control, providing fast transient response and stable operation over a wide range of input and output voltages. The integrated high-side MOSFET minimizes external component count and simplifies layout. The device is designed for high light-load efficiency, making it ideal for battery-powered systems that spend significant time in standby or low-load conditions. Typical applications include industrial power supplies, automotive body electronics, battery-powered equipment, and point-of-load regulation. The wide input range allows direct operation from 12-V and 24-V buses, as well as automotive battery voltages during cranking and load-dump conditions. When designing with the LV14360, ensure proper input and output capacitor selection to maintain stability and minimize ripple. The exposed pad should be soldered to a large copper area for effective heat dissipation, especially at high load currents.
LV52511MNZTXG - 24-Ch Bus-Controlled Linear LED Driver | onsemi
The onsemi LV52511MNZTXG is a 24-channel serial-bus controlled linear low-side LED driver housed in a 48-pin QFN (7x7 mm) package. Each of the 24 outputs can deliver up to 2.5 mA of constant current, organized as three independent 8-bit color blocks (RGB-ready) for direct display backlighting or RGB matrix control. The device integrates a serial interface for brightness programming and a single external reference resistor for current setting. A linear LED driver (also called a constant-current sink) is a specialized driver topology that regulates the current through each LED string with a regulated current source or sink rather than by switching. Linear drivers sit within the broader power-management IC hierarchy (LED driver -> display driver -> power management IC -> semiconductor) and are favored over switching drivers in noise-sensitive applications such as LCD backlights, where any PWM or switching ripple would couple into the panel and cause visible artifacts. Compared with a switch-mode LED driver, a linear driver dissipates excess VIN-VLED as heat but eliminates EMI and provides flicker-free DC current. Key features of the LV52511MNZTXG include 24 individually controllable constant-current outputs, an 8-bit PWM/ON-time resolution per channel, a single-wire or two-wire serial control interface, an integrated current reference set by one external resistor, and a wide supply range suitable for direct 3.3 V or 5 V logic rails. The 48-QFN (7x7) package provides a low thermal resistance that supports the dissipation of the linear drop, and the QSFP-style footprint simplifies PCB layout. From an architectural standpoint, the LV52511MNZTXG uses an array of matched current mirrors steered by a duty-cycle register bank. Each channel is modulated by 8-bit ON-time data loaded through the serial bus, and the three 8-channel color blocks (R, G, B) can be addressed independently for color-mixing or for driving three separate LED zones. The internal reference is multiplied by a fixed gain to set Iout, which is then trimmed for channel-to-channel matching across all 24 outputs. Typical applications include LCD panel RGB backlighting, RGB LED matrix signs and decorative lighting, large-pixel LED displays, multi-zone indicator panels, and small-format TFT display backlights. The wide channel count and serial bus also suit the device to automotive interior ambient lighting and consumer appliance status indicators. When designing with the LV52511MNZTXG, place the external reference resistor close to the Iref pin to minimize noise pickup and provide a small filter network on the supply rail. Because the device operates in the linear region, total power dissipation (Vsupply x Isum) must be checked against the package thermal resistance.

LV8860V-TLM-H - Single-Phase Full-Wave Fan Motor Driver | onsemi
The onsemi LV8860V-TLM-H is a single-phase full-wave driver for brushless DC fan motors, integrating a Bi-CMOS control stage with parallel PWM speed command input in a 16-pin SSOP package. The device supports a wide supply range, including 24 V operation, and uses Silent PWM drive to reduce reactive current and radiated EMI in fan applications. Speed is commanded through a PWM input and a built-in closed-loop architecture holds RPM stable against supply and load variation. A fan motor driver (also called a single-phase BLDC fan driver or single-phase full-wave driver) is a power-management IC that commutates a two-coil brushless DC motor by alternately switching two half-bridges in synchronization with the rotor position, typically detected via a back-EMF sensing network. Fan drivers sit hierarchically under motor drivers, which belong to the broader power management and motion control IC category. Compared to discrete MOSFET bridges driven by a microcontroller, integrated fan drivers reduce BOM count, PCB area, and acoustic noise while providing built-in protection features such as thermal shutdown, current limiting, and lock rotor detection. Key features include Silent PWM drive for reduced audible switching noise, full-wave commutation for low torque ripple, lock detection with auto-restart, soft-start functionality, and integrated thermal shutdown. The 16-pin SSOP (LSSOP) package provides a compact footprint suitable for fan-embedded PCBs. The device accepts a wide supply range up to the 24 V fan bus and supports speed control via an external PWM signal, making it compatible with standard 4-wire PWM fan command interfaces used in PC, server, and industrial cooling subsystems. The LV8860V uses a Bi-CMOS process that combines bipolar output drive strength for the power H-bridge with low-power CMOS logic for control. Full-wave commutation with Silent PWM minimizes switching losses and reduces the high-frequency acoustic content that fans couple into chassis. Built-in lock detection rotates the rotor through a forced-commutation pattern during a stall event and automatically restarts when rotation recovers, eliminating the need for an external supervisory timer. Typical applications include CPU cooling fans, server and workstation blowers, industrial inverter fans, and 24 V office-automation equipment. The wide supply range and Silent PWM drive make it well suited for applications where acoustic noise and EMI compliance are critical design constraints. When designing with this device, ensure adequate copper area under the exposed pad for thermal relief, follow the recommended input bulk capacitance to absorb the reactive return current, and verify that the lock-detection timing matches the rotor inertia of the specific fan you are pairing with this driver.

MAX14571EUD/V+ - Adj. OVP/OCP ±40V, 4.2A, 14-TSSOP-EP | Analog Devices
The Analog Devices MAX14571EUD/V+ (formerly Maxim Integrated) is an adjustable overvoltage-and-overcurrent protection IC with 100 mΩ (typ) internal MOSFET, ±40 V input fault tolerance, and programmable current limit up to 4.2 A, housed in a 14-pin TSSOP-EP package. It supports an operating input range of 4.5 V to 36 V (OVLO adjustable up to 33 V), making it ideal for 12 V/24 V industrial bus systems. An overvoltage protection (OVP) IC is a hot-swap / power-distribution switch that disconnects a downstream load from the input rail when the input exceeds a programmable threshold or when the load current exceeds a programmable limit. OVP ICs sit in the system hierarchy between discrete protection (TVS, fuse) and full PMICs: they add active, re-settable behaviour without the size or cost of a complete PMU, and they protect downstream DC-DC converters, batteries and microcontrollers from inductive transients and load-dump events. Key features include: ±40 V positive/negative input fault tolerance, 100 mΩ (typ) internal RON FET, programmable OVLO (max 33 V) and UVLO thresholds, programmable current limit up to 4.2 A with 20.7 ms (typ) blanking time, automatic retry behaviour, reverse-current blocking, and thermal-shutdown protection. The integrated MOSFET eliminates the need for an external power switch in most 4.2 A paths. The MAX14571 uses a back-to-back MOSFET topology that blocks both forward and reverse current flow when disabled. The blanking-time circuit masks inrush transients during startup so the current limiter does not false-trip on capacitive loads. The autoretry behaviour restarts the output after the retry period, which simplifies recovery from transient faults. Typical applications include USB-C PD and 5 V/12 V/24 V industrial rail protection, PLC I/O protection, load-dump protection in 24 V automotive systems, battery hot-swap, and protection of downstream point-of-load (POL) converters and microcontrollers. The MAX14571EUD/V+ variant is the automotive-grade (-40°C to +125°C) over the base MAX14571EUD+; for latched-off behaviour use MAX14572; for continuous-current limiting only use MAX14573. All three share the same 14-TSSOP-EP pinout. This page synthesizes distributor pricing (as of 2026-10-20), drop-in TSSOP-EP alternatives, and practical design notes that are not reproduced in the manufacturer datasheet.
MAX14606EWL+T - 36V OVP Protector 54mΩ WLP-9 | Maxim Integrated
The Maxim Integrated (Analog Devices) MAX14606EWL+T is a 36V overvoltage protection (OVP) IC with reverse bias blocking, housed in a 9-bump 1.29 mm × 1.29 mm WLP package. It features a 54 mΩ (typical) internal FET RON, supports an input operating range of 2.3 V to 36 V, and protects downstream low-voltage systems against voltage faults up to +36 V on the IN pin. An OVP protector is a specialized power-path protection IC that sits between a system input (such as a USB-C VBUS, charger, or hot-swap supply) and the downstream DC-DC converter or battery charger. When VIN exceeds the user-programmed overvoltage threshold, the internal MOSFET turns off within microseconds, isolating the load from the fault. The MAX14606 is part of the broader OVP IC family within Maxim's Battery Management portfolio, sitting hierarchically as OVP IC → load switch → power-path protection → power management IC → semiconductor. Compared with discrete P-FET protection schemes, an OVP IC integrates the FET, threshold detection, and thermal protection into one part. Key features include: ±50 mΩ RON typical (path loss reduction at high load current), automatic internal trip threshold selection (eliminates external resistor divider), thermal-shutdown protection against overcurrent events, reverse bias blocking (when disabled, OUT does not feed back into IN), and a CB pin for the protected downstream rail. The 9-bump WLP occupies 1.29 mm × 1.29 mm of PCB area, enabling compact designs in smartphones, wearables, and IoT modules where board real estate is critical. The MAX14606/MAX14607 family uses an integrated N-channel MOSFET architecture with internal charge-pump drive and precision bandgap-based threshold comparators. The reverse-bias blocking feature is unique to this Maxim family: when the device is disabled (CB asserted), current cannot flow backward from OUT to IN, preventing parasitic charging through the body diode of the protection FET. Thermal shutdown engages at approximately +150 °C junction temperature. Typical applications include smartphone USB charging port protection, wearable device VBUS rails, IoT sensor node power inputs, hot-swap supplies up to 36 V, and battery charger front-end protection in portable electronics. The wide 2.3 V to 36 V input range suits both 5 V USB and 12 V/24 V industrial bus systems. A key design consideration is that the MAX14606 and MAX14607 differ only in their default overvoltage threshold — confirm your application requires the MAX14606's specific trip level before substituting. The exposed-die WLP package requires careful PCB pad design and underfill consideration in high-vibration environments. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
MAX14701EWC+ - 5.9V OVP Protector with Surge | Maxim Integrated
The Maxim Integrated MAX14701EWC+ is a high-accuracy overvoltage protector (OVP) with integrated surge protection housed in a 12-pin WLP package. It features a 5.915V fixed overvoltage threshold, ultra-fast response time, and integrated TVS surge protection up to ±100V, making it a complete front-end protection IC for USB-C, PD, and 5V rails. An OVP (overvoltage protector) is a type of power management IC that sits between an upstream power source and a downstream load, disconnecting the path when the input voltage exceeds a programmed threshold. OVP ICs sit inside the broader protection IC family (OVP, OCP, OTP, reverse-polarity) and are critical for systems that must survive faulty adapters, hot-plug transients, and inductive load transients on their power inputs. Key features include ±1% accurate overvoltage trip threshold, ultra-low on-resistance internal MOSFET, integrated back-to-back TVS for surge robustness, and minimal quiescent current. The MAX14701EWC+ is specifically designed for systems that need to survive non-compliant USB Type-C adapters and 5V rails where accidental application of high voltage could damage downstream components. Typical applications include USB Type-C/PD port protection, smartphones and tablets, IoT devices powered from 5V adapters, and any system that must survive up to 28V on a 5V rail. The 12-pin WLP package allows compact placement near the input connector. When designing with this part, place the device as close to the input connector as possible to maximize surge clamping effectiveness. The integrated TVS reduces external component count compared to discrete FET + TVS solutions.
MAX14701EWC+T - 5.915V OVP Protector w/ Surge | Maxim Integrated
The Analog Devices (formerly Maxim Integrated) MAX14701EWC+T is a fast-response, high-accuracy overvoltage (OVP) protector with integrated surge protection in a 12-bump WLP (WLCSP) package. The device clamps VOUT to a factory-set 5.915V threshold when VIN exceeds the threshold, and includes TVS-style surge protection on the input to survive transients typical of USB Type-C, BC1.2, and similar hot-plug ports. An OVP (overvoltage protector) is a power-path protection IC placed between an upstream supply (charger, USB VBUS, external adapter) and a downstream load (PMIC, SoC, battery). Its role is to disconnect or clamp the rail when the input voltage rises above a safe limit, preventing damage to sensitive downstream silicon. OVP protectors sit in the power management hierarchy below TVS diodes (which absorb the energy) and above PMIC input stages (which assume safe input voltage). Fast OVP response (sub-microsecond turn-off) is critical when protecting processors rated only to 5V from mis-wired 12V or 20V USB-PD adapters. Key features include a 5.915V factory-trimmed overvoltage threshold with ±0.5 percent accuracy, sub-microsecond OVP response time, internal 100 mA to 1 A current-limit switch, and built-in surge protection rated for IEC 61000-4-5 (8 kV contact / 15 kV air ESD-style transients). The device operates from a wide 2.4V to 5.5V supply range while monitoring higher-voltage input transients, and provides an open-drain FLAG output to indicate OVP events. The WLP-12 (1.5 mm x 1.8 mm wafer-level package) is approximately 80 percent smaller than SOT-23-6 alternatives, enabling compact mobile and wearable designs. The MAX14701 uses a back-to-back MOSFET architecture with an integrated charge pump for gate drive, achieving low on-resistance and clean turn-off during overvoltage events. Internal blanking timers prevent false trips on capacitive load transients during hot-attach. Typical applications include smartphone and wearable charging path protection, USB Type-C VBUS protection, tablet and ultrabook input protection, Bluetooth and TWS earbud overvoltage protection, IoT sensor node power path, and any 5V rail exposed to user-replaceable cables or adapters. For higher voltage rails (12V / 20V USB-PD), consider the MAX14702 (13.95V threshold) or MAX14703 (23.05V threshold) in the same WLP-12 footprint. Design tip: place the MAX14701EWC+T within 10 mm of the input connector so the internal TVS clamp can absorb surge energy before it propagates downstream; place a 1 uF ceramic bypass cap on VOUT.

MAX14807ECB+ - 220Vpp 2.2A Dual HV Pulser | Analog Devices
Analog Devices MAX14807ECB+ is a dual, high-voltage 2.2 A analog pulser with 220 Vpp waveform output, packaged in a 48-pin LQFP. The device generates high-voltage arbitrary waveforms or pulses for driving piezoelectric transducers in ultrasound systems without requiring an external transformer. It provides selectable analog-mode gain of 28 dB or 40 dB and supports both analog and digital operating modes. An analog pulser is a specialized high-voltage driver that converts low-voltage input signals into bipolar or unipolar waveforms suitable for piezoelectric loads. Within the product hierarchy, the MAX14807 is a high-voltage integrated circuit, analog signal-conditioning IC, ultrasound transducer driver, and power-management interface for piezoelectric systems. Its integrated approach simplifies the signal path between a waveform generator and a high-voltage transducer. The principal specifications include 2.2 A output current, operation to 220 Vpp, a selectable 28 dB or 40 dB differential gain, and an integrated 25 ohm active clamp. The Class AB push-pull analog output stage uses an externally set bias current. These features allow the MAX14807 to produce arbitrary analog waveforms while also providing a controlled low-impedance discharge path to ground during pulse transitions. In digital mode, the device can generate programmed high-voltage pulses rather than continuously amplified analog waveforms. This dual-mode architecture supports imaging systems that need flexible waveform generation for different transducer operating sequences. The gain-selectable differential amplifier, active clamp, and integrated high-voltage output stage reduce the amount of external high-voltage circuitry required, although the datasheet remains essential for correct high-voltage layout and safe operating limits. Typical applications include ultrasound imaging systems, medical diagnostic equipment, industrial nondestructive-testing transducers, acoustic-emission instrumentation, and other piezoelectric drive circuits. The device is particularly relevant where a 220 Vpp waveform and 2.2 A drive capability are required from a compact mixed-signal IC. Board-level implementation requires careful attention to high-voltage creepage, clearance, isolation, return-current paths, output-loop inductance, and transducer protection. Input and output grounding should follow the manufacturer reference layout because rapidly switching high-voltage pulses can produce significant EMI and ground-bounce effects. The 48-LQFP thermal and return-path design also depends on the PCB copper available under the device. This product page consolidates the verified manufacturer specifications, current distributor references, functional alternatives, and application-specific design guidance. It also distinguishes explicitly confirmed drop-in replacements from similarly described devices that have not been demonstrated to be pin-to-pin compatible.
MAX15024AATB+T - 8A Single MOSFET Gate Driver | Analog Devices
The Analog Devices MAX15024AATB+T is a high-speed single low-side MOSFET gate driver capable of sinking and sourcing 8A peak current, packaged in a 10-pin TDFN-EP (3x3 mm) with exposed pad. The device operates from a wide 4.5V to 28V supply rail and accepts TTL input logic levels, achieving a typical propagation delay of 16 ns and supporting switching frequencies up to 1 MHz with large capacitive loads. A low-side MOSFET gate driver is a power-management IC that sits between a low-power control signal (from a microcontroller, PWM controller, or logic gate) and the gate of a power MOSFET or IGBT. It provides high peak source/sink current to quickly charge and discharge the MOSFET gate capacitance, enabling fast switching transitions. Gate drivers belong to the broader category of power MOSFET drivers within power management ICs, and they are essential building blocks in switch-mode power supplies (SMPS), motor drives, Class-D amplifiers, synchronous rectifiers, and DC-DC converters where direct logic-level drive is too weak. Key features of the MAX15024 include independent source and sink output transistors, internal logic to prevent shoot-through, and a thermally enhanced exposed-pad package that dissipates switching losses efficiently. The TTL input thresholds make it compatible with 3.3V and 5V microcontrollers without level shifters, while the wide 4.5V to 28V operating range suits 5V, 12V, and 24V industrial bus rails. The driver can deliver 8A peak (typical) into the gate of large power MOSFETs, dramatically reducing switching loss and improving power-conversion efficiency at high frequencies. Internally, the MAX15024AATB+T uses a BiCMOS process to combine low-power CMOS logic with high-current bipolar output stages. The split source/sink output paths allow designers to independently tune rise and fall times by inserting series resistors between the IC outputs and the MOSFET gate, providing fine-grained control of EMI and switching loss trade-offs. The exposed thermal pad connects to the driver ground and serves as the primary heat-dissipation path, allowing the part to sustain high-frequency switching without thermal shutdown. Typical applications include synchronous rectification in isolated DC-DC converters, high-current Class-D audio amplifiers, motor-driver H-bridges, and power-ORing circuits. The MAX15024 is also widely used as an auxiliary gate driver in telecom brick converters, industrial 24V-input power modules, and digital-control systems requiring fast, high-current MOSFET switching. When designing with this part, place input and bypass capacitors close to the VDD pin and route the high-current gate-drive traces as short and wide as possible to minimize parasitic inductance. The exposed pad must be soldered to a sufficiently large copper pour (typically 1 square inch) to keep junction temperature within the -40C to +125C operating range during continuous 1 MHz switching.

MAX15024AATB/V+T - 8A Single Low-Side MOSFET Driver | Analog Devices
The Analog Devices (formerly Maxim Integrated) MAX15024AATB/V+T is a single-channel, high-speed, high sink/source current low-side gate driver IC in a 10-pin TDFN (3x3 mm) exposed-pad package. The part delivers 8 A peak output current, a 16 ns typical propagation delay, and is capable of switching at frequencies up to 1 MHz with large capacitive loads such as power MOSFETs and IGBTs. A gate driver is a power-management IC that sits between a low-power control signal (from a microcontroller, FPGA, or analog controller) and the gate of a discrete power switch (typically a MOSFET or IGBT). Because microcontrollers cannot source or sink the multi-ampere currents required to charge and discharge a power MOSFET's gate quickly, the gate driver acts as a high-current buffer. Within the broader IC hierarchy, the MAX15024 belongs to the PMIC (Power Management IC) category, specifically the MOSFET/IGBT gate driver sub-family, often called power MOSFET drivers or low-side drivers. Its role is essential in any switched-power topology where switching losses, dead-time control, and dv/dt immunity matter. Key features include 4.5 V to 28 V supply range (VDD), 8 A peak sink/source current, internal source-and-sink output transistors with independent source and sink pins for rise/fall-time control, 16 ns typical propagation delay, inverting and non-inverting logic inputs, TTL/CMOS-compatible inputs, and a -40 C to +125 C automotive-grade operating temperature range (the /V suffix denotes the automotive-qualified version). The architecture uses a BiCMOS push-pull output stage with separate SOURCE and SINK pins that connect to the gate via small gate resistors, allowing the designer to tune rise and fall times independently. This dual-path topology reduces switching losses and EMI by controlling the trade-off between dv/dt, ringing, and cross-conduction. The internal logic accepts inverting or non-inverting inputs selected via a single pin, eliminating the need for an external inverter stage. Typical applications include synchronous-rectifier MOSFET driving in isolated DC-DC converters, low-side drive for buck and half-bridge topologies, motor-driver pre-drivers, Class-D audio amplifier output stages, and high-frequency switch-mode power supplies (SMPS) where fast edges minimize switching loss. When designing with this part, place the TDFN exposed pad over a continuous ground copper pour to dissipate the internal switching losses, and keep the gate-loop return path tight (gate resistor -> driver -> source -> back to ground) to limit parasitic inductance.

MAX15103EWL+T - 3A LDO Regulator 1.7-5.5V | Analog Devices
The Analog Devices (formerly Maxim Integrated) MAX15103EWL+T is a small, low-dropout linear regulator delivering up to 3A of output current from a 1.7V to 5.5V input supply, housed in a 15-ball WLP (Wafer Level Package) measuring 2.7 mm x 1.6 mm. The device provides an adjustable output from 0.6V to 5.2V with an output accuracy of ±1.6%, and it includes a guaranteed dropout voltage of less than 200 mV at full load. An LDO (Low-Dropout) linear regulator is a type of voltage regulator that maintains a stable output voltage even when the input voltage is very close to the output voltage. LDOs are widely used as a final post-regulation stage after switching converters, where they attenuate high-frequency ripple and noise that the switching converter cannot fully suppress. Within the power management hierarchy, the MAX15103 belongs to the category of linear regulators, which sit under power management ICs in the broader semiconductor taxonomy. Because LDO regulators dissipate (VIN - VOUT) x IOUT as heat, they are best suited to low-voltage, high-current rails where the input-to-output headroom is small. Key features of the MAX15103EWL+T include a foldback current limit for output-stage protection, internal p-channel pass transistor architecture for low dropout operation, thermal shutdown protection, and a power-good output for sequencing in multi-rail systems. The device requires only small input and output capacitors and is designed for minimal external component count. The internal architecture uses an advanced BiCMOS process with a p-channel MOSFET pass device, which permits true low-dropout operation and minimizes ground-pin current. The ±1.6% output accuracy is maintained across line, load, and temperature variations, ensuring tight regulation for downstream digital loads such as ASICs, FPGAs, and high-speed SerDes. The foldback current limit protects the regulator by reducing the output current during short-circuit or overload events rather than abruptly latching off, allowing recovery when the fault clears. Typical applications include networking and datacom systems, server point-of-load regulation, DDR memory VTT termination, FPGA and ASIC core supplies, and distributed power architectures in telecom equipment. The wide input range of 1.7V to 5.5V makes the device directly compatible with both 3.3V and 5V intermediate bus voltages. When designing with the MAX15103, ensure that PCB layout provides adequate copper thermal relief on the WLP land pads. Although the part is rated for 3A, thermal dissipation is highly layout-dependent; using a 4-layer board with thermal vias beneath the WLP balls is recommended for continuous full-load operation.

MAX15300ETI+ - Auto-Comp Digital PoL Controller, QFN-28 | Maxim Integrated
The Maxim Integrated MAX15300ETI+ is an Auto-Comp digital point-of-load (PoL) controller IC designed for non-isolated DC-DC step-down converter topologies in distributed power architectures. The device integrates a PMBus-compatible digital interface for adaptive voltage positioning, telemetry, and adaptive compensation, and it delivers switching controller functions across an input range suitable for nominal 3.3 V, 5 V, and 12 V intermediate bus converters commonly found in servers, telecom, and embedded computing platforms. A point-of-load controller is a device category that sits between a board-level DC intermediate bus and a load IC (CPU, SoC, FPGA, ASIC) and uses external MOSFETs to deliver a tightly regulated low-voltage, high-current rail. Auto-Comp controllers like the MAX15300 belong to the switched-mode power supply (SMPS) controller family, which in turn falls under the broader power management IC hierarchy. Adaptive digital compensation eliminates the manual loop-tuning step required by traditional analog PWM controllers, reducing engineering time across multiple output voltages on a single board. Key features of the MAX15300ETI+ include programmable output voltage via PMBus commands, automatic loop compensation, current and voltage telemetry for monitoring, fault protection with configurable thresholds, synchronization to an external clock, and a power-good indicator. The controller supports multi-rail sequencing and margin testing through the digital interface, which is essential in systems where downstream rails must come up in a deterministic order. The exposed pad on the QFN package improves thermal conduction from the internal driver stages to the PCB copper pour. The MAX15300ETI+ uses a peak-current-mode control architecture with an internal ADC sampling the output voltage, and adjusts compensation parameters automatically based on the output filter characteristics, switching frequency, and load transients. The digital core can log fault events and report them via the PMBus STATUS registers, simplifying board-level diagnostics during factory test and field operation. Programmable switching frequency supports trade-offs between inductor size, switching loss, and transient response. Typical applications for the MAX15300ETI+ include core and I/O voltage rails for networking ASICs, FPGA and SoC auxiliary rails in industrial embedded systems, server memory and processor point-of-load regulators, and base-station digital signal processing card supplies. The PMBus interface also enables remote firmware updates and adaptive voltage scaling in energy-aware data center designs. When designing with this controller, choose external MOSFETs with adequate SOA margin at the programmed switching frequency, and place the current-sense network as close to the inductor as PCB layout allows to minimize noise pickup on the feedback path. The exposed pad must be soldered to a continuous ground copper pour. This page synthesizes distributor pricing, drop-in alternative candidates, and practical design notes not found in the manufacturer datasheet, supporting faster component selection by power and digital hardware engineers.
MAX15300ETI+T - Auto-Comp Digital PoL Controller | Maxim Integrated
The Maxim Integrated MAX15300ETI+T is an auto-compensating digital Point-of-Load (PoL) controller IC housed in a 28-pin TQFN-EP (5x5 mm) package designed for non-isolated DC-DC step-down converter applications. It supports input voltages from 4.7V to 24V and drives external MOSFETs to deliver output voltages from 0.6V to 5.25V at up to 30A+ depending on external component selection, with PMBus 1.2/1.3-compliant digital telemetry for voltage, current, temperature, and fault status. A digital Point-of-Load controller is a power-management IC that regulates a low-voltage, high-current DC rail directly at the point where the load (CPU, ASIC, FPGA, memory) consumes it, replacing traditional analog PWM controllers. PoL controllers sit one tier below an intermediate bus converter (typically 12V) and one tier above the load device in the distributed power architecture. The 'Auto-Comp' feature refers to the controller's ability to autonomously measure the output filter characteristics and compute optimal PID loop compensation, eliminating the manual design step normally required for buck converters. Key features include adaptive dead-time control, cycle-by-cycle current limiting, pre-bias monotonic startup, and four selectable switching frequencies (600/800/1000/1200 kHz). The internal 8-bit ADC digitizes output voltage, current, and temperature for closed-loop regulation and PMBus reporting, and fault events trigger configurable responses including retry, latch-off, or warning-only behavior. The PMBus interface enables remote margining, sequencing, and real-time telemetry across a 2-wire SMBus-compatible serial bus. Typical applications include powering FPGAs, ASICs, and DSPs from 12V intermediate bus architectures, telecom and networking line cards, server motherboard DC-DC VRM stages, base-station power modules, and any distributed-power PCB where adaptive compensation simplifies design-in. The TQFN-EP package provides a low thermal-resistance path for the controller itself, although most thermal dissipation is in the external MOSFETs it drives. Designers should pair the MAX15300ETI+T with a current-sense element (Rsense or DCR sensing) and follow the manufacturer's inductor and capacitor selection guidelines to achieve the desired ripple and transient response. The PMBus device address is set by an external resistor, allowing multiple controllers on the same bus. Programmable soft-start and output-voltage margining make the device especially attractive for multi-rail systems that require coordinated sequencing.
MAX1558HETB+ - Dual 1.2A USB Power Switch | Analog Devices
The Analog Devices MAX1558HETB+ is a dual, programmable-current, current-limited USB power switch with autoreset, providing up to 1.2A per channel in a 10-TDFN 3 mm x 3 mm package. Each channel includes current limiting and automatic fault recovery for downstream USB ports, cables, and connected loads. A USB power switch is a power-distribution interface IC placed between a system supply and a USB port. It regulates current delivered to a downstream device, isolates faults, and protects the host when a cable or load causes excessive current. The MAX1558 family is designed for compact USB power-distribution systems where limited board area, fault recovery, and controlled current behavior are important. The MAX1558HETB+ supports a 2.7V to 5.5V operating range and offers programmable current limiting. The manufacturer describes the MAX1558 and MAX1558H as dual switches with autoreset that latch the channel off when a short persists for more than 20ms, then test the output and automatically restart after the short is removed. The MAX1558H designation also indicates the temperature-grade variant described in the manufacturer documentation. Each channel is intended to deliver up to 1.2A, making the device suitable for USB power-distribution designs requiring independent two-channel protection. The 10-TDFN package is a compact no-lead surface-mount format with an exposed pad used for thermal management and PCB layout considerations. Exact continuous-current limits, current-limit accuracy, and thermal ratings should be confirmed against the manufacturer datasheet for the selected production variant. Typical applications include USB hubs, USB battery-charging ports, portable-device power rails, industrial USB controllers, and dual-rail USB distribution boards. Designers should account for the voltage drop across the switch when calculating downstream power and verify current-limit settings, startup behavior, and thermal performance under worst-case load conditions. The key design consideration is fault containment: the autoreset mechanism protects the system by removing a shorted channel after the specified delay, but the source rail must still have adequate protection for repeated fault events. Placement near the USB connectors can reduce trace resistance and improve fault-current behavior. This page summarizes verified product positioning, package information, and sourcing data, while highlighting design checks that should be completed against the manufacturer datasheet and the completed board layout.
MAX16011TAA+T - Overvoltage Protector, 5.5–72V, 2-Channel Supervisor TDFN-8 | Maxim Integrated
The Maxim Integrated (Analog Devices) MAX16011TAA+T is an ultra-small, low-power overvoltage protection/detection IC with two independent comparators for monitoring undervoltage and overvoltage conditions simultaneously. The device operates over a wide 5.5V to 72V supply voltage range, making it suitable for high-voltage, high-transient telecom and industrial systems. The MAX16011TAA+T is housed in an 8-pin TDFN-EP (3x3 mm) surface-mount package with exposed pad for improved thermal performance. What is a voltage supervisor IC? A voltage supervisor (also called a reset or monitor IC) is a power management device that continuously observes a supply rail and asserts a reset or fault signal when the voltage moves outside a programmable window. Supervisors sit at the bottom of the power management hierarchy: PMIC -> supervisor/monitor -> discrete comparators, providing system-level protection that simpler regulators cannot. The MAX16011TAA+T extends this concept to high-voltage rails by integrating two window comparators in a single 3x3 mm package. Key features include open-drain outputs rated to 72V, an active-high enable input for power sequencing, a selectable active-high/low OUTB output polarity, and a built-in 1.245V/1.223V reference. The two comparators are designed for monitoring both undervoltage and overvoltage events independently, enabling window-watchdog-style supervision in compact form factor. The TDFN-8 EP package is specified for -40C to +125C automotive temperature grade operation. The MAX16011 uses an internal bandgap reference driving two window comparators whose trip points are set by external resistor dividers on the IN1/IN2 inputs. Open-drain outputs swing to the system voltage rail, allowing direct interface to downstream controllers, FPGAs, or upstream disconnect FETs without level translation. According to the manufacturer datasheet, the device maintains stable trip-point accuracy across the full 5.5V to 72V input range. Typical applications include telecom equipment overvoltage protection, industrial 24V/48V rail monitoring, battery stack management, notebook and server power rails, and automotive load-dump protection. The wide input range also makes it suitable for protecting downstream circuits from transients on long cable runs. Design consideration: choose the external resistor divider values so that undervoltage and overvoltage trip points fall inside the input common-mode range of the comparators, and place decoupling close to the supply pin to handle high-voltage transients. This page synthesizes distributor pricing from DigiKey/Mouser/LCSC, drop-in alternative pin-compatible parts, and practical supervisor design notes not found in the standalone datasheet, giving engineers a single page to evaluate the MAX16011TAA+T against functional equivalents.
MAX16016LTBS+T - Low-Power μP Supervisor with Battery Backup | Maxim Integrated
The Maxim Integrated MAX16016LTBS+T is a low-power microprocessor supervisory circuit that monitors power supplies, provides battery-backup control, and chip-enable (CE) gating for memory write protection in microprocessor-based systems, housed in a 10-pin TDFN (3x3 mm) package with an exposed pad. The device operates over the industrial temperature range of -40°C to +85°C and integrates multiple supervisory functions in a single IC to improve system reliability in space-constrained designs. A microprocessor supervisory circuit (also called a voltage supervisor, reset IC, or power monitor) is a dedicated IC that watches one or more system supply rails and asserts a reset signal whenever the rail falls outside a valid window. It sits between the power supply and the host MCU or CPU as part of the broader power management hierarchy (supervisor -> power monitor -> power management IC -> mixed-signal semiconductor), providing deterministic boot behavior, brownout protection, and orderly recovery from power-loss events that a generic voltage regulator cannot guarantee. Key features include a single supervisor channel with push-pull, totem-pole reset output, an integrated battery-backup switchover path, chip-enable gating for SRAM/EPROM write protection, and a nominal supply monitor threshold of 1.62 V. The compact 10-pin TDFN package measures only 3 mm × 3 mm with a maximum seated height of 0.8 mm, making the part suitable for handheld, portable, and densely populated industrial boards where board area is at a premium. Internally, the MAX16016 family uses a precision bandgap reference and comparator chain to detect undervoltage conditions, combined with a low-on-resistance MOSFET for transparent battery-backup switching. The chip-enable gating logic prevents spurious write cycles to external memory during power transitions, which is critical for deterministic firmware behavior in 1.8 V, 2.5 V, 3.0 V, 3.3 V, and 5 V logic systems. Compared with discrete reset solutions, the MAX16016 reduces external component count, simplifies PCB layout, and improves long-term reliability. Typical applications include supervisory control in portable battery-backed equipment, point-of-sale terminals, industrial controllers, and any μP system that requires power-on reset (POR), brownout reset, battery switchover, and memory write protection. The part is particularly suited to designs that must retain SRAM contents through primary power loss. When designing with the MAX16016LTBS+T, place the decoupling capacitor (per datasheet typical application) as close as possible to the VCC pin and verify the exposed pad is soldered to a sufficient copper pour for thermal and electrical performance. Carefully review the battery-backup current path and confirm the backup supply voltage is within the device's specified range to ensure proper switchover behavior. This page synthesizes distributor pricing, drop-in supervisor alternatives from the same product family, and practical design notes for portable and battery-backed systems - content that complements rather than duplicates the manufacturer datasheet.
MAX16088XS44F+T - 1.2V Voltage Supervisor, SC70-4 | Maxim Integrated
The Maxim Integrated (Analog Devices) MAX16088XS44F+T is an ultra-low-power, single-channel voltage supervisor (reset IC) featuring a factory-trimmed 4.375V threshold in a 4-pin SC70 package. Designed to monitor microprocessor (µP) and ASIC supply rails, this supervisor asserts a reset signal whenever the monitored VCC falls below the threshold, holding it asserted for a minimum timeout period after VCC recovers - preventing code-execution errors during brownouts, power-up, and power-down events. A voltage supervisor is a type of power management integrated circuit (PMIC) that belongs to the supervisors-and-reset IC category. Within the broader system hierarchy, supervisors fall under power management ICs - semiconductors that regulate, monitor, and protect voltage rails. Supervisors specifically ensure deterministic processor behavior by forcing a known reset state whenever the supply rail becomes unreliable. This is critical for embedded systems where uncontrolled code execution during brownouts can corrupt flash memory, registers, or cause mechanical/communications faults. Key features of the MAX16088XS44F+T include a 4.375V ±1.5% threshold accuracy, an open-drain active-low RESET output, an ultra-low 0.7 µA (typical) supply current that makes it ideal for battery-powered applications, and a 200 ms minimum reset timeout. The SC70-4 package occupies only ~2.0 mm × 2.1 mm of PCB area - one of the smallest footprints in the supervisor category - and operates over a -40°C to +85°C extended industrial temperature range. The wide VCC supply range of 1.0V to 5.5V allows monitoring of common 3.3V, 3.0V, 2.5V, 1.8V, and 1.2V rails from the same part. Architecturally, the MAX16088XS44F+T uses a precision bandgap reference and comparator core to compare VCC against the trimmed threshold, combined with an internal timing generator for the reset pulse-width. The design avoids the need for an external timing capacitor - unlike many legacy supervisors such as the MAX809 - by integrating a fixed-factory timeout. Typical applications include battery-powered IoT sensor nodes, wearable health monitors, portable consumer electronics, MCU/SoC rail monitoring, energy harvesting nodes, and industrial sensor endpoints. The low quiescent current (0.7 µA typ.) makes it especially suitable where sleep-mode drain dominates system budgets. Designers should choose a pull-up resistor on RESET (open-drain) sized appropriately for the load capacitance to meet reset rise-time requirements, and verify that VCC ramp time is faster than the device's minimum VCC slew specification. For more margin, consider the MAX16087 variant family with adjustable thresholds. This page synthesizes distributor pricing, cross-brand substitutes, application notes, and design guidance for the MAX16088XS44F+T - information typically scattered across multiple datasheets and distributor pages.
MAX1631EAI+T - Dual Buck PWM Controller 28-SSOP | Maxim
The Maxim Integrated MAX1631EAI+T (now under Analog Devices) is a dual-output, current-mode, step-down DC-DC switching controller IC for notebook and battery-powered systems. Housed in a 28-pin SSOP package, the device operates over a 4.2V to 30V input range and provides two adjustable outputs (selectable to 3.3V and 5V fixed via preset pins) at up to 96% efficiency, with on-chip MOSFET drivers. The switching frequency is programmable from 200 kHz to 300 kHz, and the duty cycle reaches 99%, allowing low-dropout operation on the high-side rail. What is a step-down DC-DC controller? A step-down (buck) controller is a switch-mode power supply IC that regulates an output voltage lower than the input by rapidly switching an external power MOSFET and storing energy in an external inductor. The MAX1631 family belongs to the hierarchy of voltage regulator -> switching regulator -> step-down controller -> PWM current-mode controller -> power management IC, and is widely used where high efficiency at varying battery voltages is required. Key features include on-board power-up sequencing, power-good signaling with programmable delay, digital soft-start to limit inrush current, secondary winding control for auxiliary outputs, low-dropout (LDO) circuitry, and internal frequency-compensation networks. The MAX1631EAI+T supports dual adjustable outputs that can be preset to 3.3V and 5V, making it well-suited for powering system logic, memory, and I/O rails from a single battery or adapter source. The architecture combines current-mode PWM control with an adaptive idle mode that skips switching cycles at light loads, sustaining high efficiency across the entire load range. Internal drivers can directly drive external N-channel MOSFETs without external gate drivers, simplifying the BOM. Housed in a 28-SSOP package (5.30 mm body width, 0.65 mm pitch), the part dissipates moderate thermal load at typical notebook power levels. Typical applications include notebook computer main supplies (CPU core + I/O), battery-powered portable instruments, point-of-load regulators downstream of an AC adapter, and embedded systems requiring 3.3V/5V dual rails from a single 12V or 19V bus. The on-board power-good and sequencing features target multi-rail architectures where CPU, chipset, and peripheral rails must come up in a defined order. When designing with this device, careful inductor selection and output capacitor ESR are critical for stability. The 28-SSOP package has a higher thermal resistance than QFN equivalents, so copper area on the PCB beneath the exposed pad (or wide traces on the SSOP leads) is recommended for sustained full-load operation at high VIN. A well-designed snubber across the external switching MOSFET reduces ringing and EMI. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, giving engineers a single source for selecting, sourcing, and validating the MAX1631EAI+T in new and legacy designs.
MAX17262REWL+T - 5.2µA 1-Cell Fuel Gauge with ModelGauge m5 | ADI
The Analog Devices (formerly Maxim Integrated) MAX17262REWL+T is an ultra-low-power 1-cell fuel-gauge IC implementing the proprietary ModelGauge m5 EZ algorithm, supporting both LiFePO4 and Li-ion battery chemistries in a compact 9-pin WLP (1.47 mm × 1.45 mm) package. Headline parameters include 5.2 µA quiescent current, internal current sensing (no external sense resistor required), and best-in-class accuracy for battery capacities from 30 mAhr to 6 Ahr. What is a fuel-gauge IC? A fuel-gauge IC is a battery-management semiconductor that continuously estimates remaining state-of-charge (SOC), state-of-health (SOH), time-to-empty, and runtime for a rechargeable cell. It belongs to the broader hierarchy of battery management ICs → power management ICs → analog mixed-signal semiconductors. The MAX17262 family specifically uses ModelGauge m5 EZ, which combines the short-term accuracy of a coulomb counter with the long-term stability of a voltage-based ModelGauge algorithm, while eliminating battery characterization requirements through EZ configuration. Key features include ±1% SOC accuracy over the full operating range, I2C/SMBus-compatible interface, on-chip temperature sensing, and built-in battery insertion detection. The internal current sense eliminates the bulky external sense resistor that older coulomb-counter designs required, reducing BOM cost and PCB area while improving noise immunity. The device also includes SHA-256 authentication support for battery-pack security applications requiring anti-counterfeit protection. Technically, the MAX17262 samples battery voltage, current, and temperature at a low duty cycle to minimize quiescent current to 5.2 µA, enabling extended shelf life and runtime in always-on battery applications. The ModelGauge m5 algorithm fuses periodic OCV (open-circuit-voltage) measurements with continuous coulomb-count tracking, providing accurate SOC reporting even during high-dynamic-load conditions where pure coulomb counters drift or pure voltage-based gauges become unreliable. Typical applications include wearables (smartwatches, fitness bands, hearables), IoT sensor nodes, Bluetooth trackers, TWS earbuds charging cases, single-cell medical devices, and ultra-thin portable electronics where PCB real estate is constrained. The 9-WLP package occupies only 2.13 mm², making it suitable for the smallest form-factor designs. When designing with the MAX17262, pay attention to PCB layout for the WLP package — the WLP requires NSMD pads and a clean ground plane under the die for accurate temperature sensing. The I2C lines require 4.7 kΩ pull-ups to the host logic level, and the BAT pin must connect to the cell positive terminal through a low-impedance trace. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the standalone manufacturer datasheet, with cross-validated parameters from Analog Devices, DigiKey, Mouser, and LCSC listings.
MAX17502FATB+T - 60V, 1A Sync Step-Down DC-DC | Maxim/ADI
The Maxim Integrated (Analog Devices) MAX17502FATB+T is a high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated MOSFETs that delivers up to 1 A of load current from a 4.5 V to 60 V input rail and regulates a fixed 5 V output in a 10-pin TDFN exposed-pad (TDFN-EP) package. Housed in a compact 3 mm x 2 mm TDFN-EP footprint, it operates at a 600 kHz switching frequency and uses peak-current-mode control with internal compensation, eliminating the need for an external compensation network. The device maintains ±1.7% output accuracy over the full -40 °C to +125 °C temperature range. A synchronous buck (step-down) DC-DC converter is a switching regulator that uses actively controlled high-side and low-side MOSFETs to convert a higher DC input voltage into a lower, regulated DC output voltage with significantly higher efficiency than a linear regulator. The MAX17502 belongs to the step-down regulator -> DC-DC converter -> power management IC -> semiconductor hierarchy, and is optimized for harsh industrial and automotive environments where wide input transients are common. Key features include a wide 4.5 V to 60 V input range, integrated 180 mΩ high-side and 120 mΩ low-side MOSFETs, internal loop compensation, programmable soft-start, and a power-good (PGOOD) output for rail sequencing. The fixed 5 V output variant eliminates external feedback resistors, while the adjustable variant covers 0.9 V to 92% of VIN. Shutdown current drops below 1 µA for energy-saving standby modes. The internal architecture combines a peak-current-mode controller with a precision reference and adaptive dead-time control, achieving up to 92% efficiency. The 600 kHz switching node allows the use of small ceramic input and output capacitors while keeping fundamental switching noise outside the AM band, which simplifies EMI filtering. Typical applications include industrial 24 V and 48 V bus systems, point-of-load regulators after a PFC stage, distributed supply rails in factory automation, battery-powered portable instruments, HVAC controllers, and eMobility accessories. Designers choose this part when they need a tiny, fully synchronous 1 A regulator that tolerates automotive load-dump events. When designing with this part, keep the input capacitor loop and the high-side MOSFET loop as short as possible to minimize switching-node ringing, and connect the exposed pad to a continuous ground copper plane to keep junction temperature within the 150 °C limit. For high VIN-to-VOUT ratios, derate output current to stay within the SOA shown in the manufacturer datasheet. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical PCB design notes that go beyond what the manufacturer datasheet alone provides, making component evaluation and sourcing faster for engineers.
