TEA2096T/1J - GreenChip Dual SR Controller | NXP | LLC Power
The NXP TEA2096T/1J is a GreenChip dual synchronous rectifier (SR) controller IC for the secondary side of switched-mode power supplies, housed in an 8-pin SO (SO-8) package. It is a dedicated SR controller for resonant converters such as LLC topologies, with two driver stages for driving two SR MOSFETs and an adaptive gate drive method for maximum efficiency at any load. A synchronous rectifier controller replaces the rectifier diodes on the secondary side of an SMPS with MOSFETs driven by a dedicated controller, dramatically reducing conduction losses. Within the power management hierarchy, the TEA2096T sits in the secondary-side controller category of switching controller ICs. Where a diode drop of 0.5 V to 0.7 V wastes power at high output currents, a synchronously driven MOSFET with low RDS(on) can cut that loss by a factor of 5 to 10, which is why SR controllers are standard in high-efficiency adapters and server power stages. Key characteristics of the TEA2096T include its dual-channel architecture (two SR MOSFET drivers in one SO-8 package), an adaptive gate drive scheme that optimizes conduction time and dead-time at any load, and GreenChip design principles targeting high efficiency and low standby power. The dual-driver integration reduces external component count versus single-channel SR controllers in center-tapped secondary windings. Technically, the TEA2096T senses the drain-source voltage of the SR MOSFETs to detect current direction, turning the gates on when the body diode conducts and off before reverse current flows. This adaptive control prevents cross-conduction and reverse-current losses that reduce efficiency in fixed-timing SR schemes, especially at light load where fixed-delay controllers typically mis-time gate transitions. Typical applications include LLC resonant converters in AC-DC adapters, USB-PD fast chargers, and server/telecom power supplies with center-tapped or full-bridge secondary rectification. High-current 5 V and 12 V rails benefit most, where diode losses dominate. Design consideration: proper placement of the sense lines close to the SR MOSFET drains is critical; long sense traces pick up switching noise and can cause false turn-on, degrading efficiency or damaging the MOSFETs.

TEA2376BT-1Y - Digital Interleaved PFC Controller | NXP
The NXP Semiconductors TEA2376BT/1Y (TEA2376BT-1Y) is a digital configurable two-phase interleaved Power Factor Correction (PFC) controller for high-efficiency power supplies, operating in discontinuous conduction mode (DCM) or quasi-resonant (QR) mode with valley switching over a switching frequency range of 40 kHz to 130 kHz, housed in a 14-pin SOIC (SO-14, 3.90 mm width) surface-mount package. A PFC controller is a power management IC that shapes the input current waveform of an AC-DC power supply so that it follows the input voltage, maximizing power factor and minimizing harmonic distortion. Within the power-supply control hierarchy, the PFC stage sits between the input rectifier and the downstream DC-DC converter, ensuring compliance with harmonic-current regulations such as those applied to TVs, servers and industrial equipment. Key features include digital configurability that reduces external component count, two-phase interleaving that halves input ripple current and spreads thermal stress across two boost stages, and valley switching that minimizes switching losses for high efficiency. For light-load conditions the controller supports phase shedding and burst mode operation, improving standby and low-load efficiency in modern energy-regulated designs. Technically, the TEA2376 family implements its control loop digitally, allowing configuration of protection thresholds, frequency ranges and phase management without resistor-capacitor tuning. Discontinuous conduction and quasi-resonant operation avoid hard-switching turn-on losses, while interleaving cancels ripple currents at the PFC input, simplifying EMI filter design. Typical applications include TV power supplies, computing and server power supplies, and industrial power systems where a regulated DC bus (typically around 380-400 V from a boost PFC stage) feeds a downstream flyback or LLC converter. The interleaved topology suits power levels where a single boost phase would be thermally or ripple limited. When designing with the TEA2376BT/1Y, verify the supply voltage range (22 V per distributor data) and configure the switching-frequency window so that valley switching remains valid across the full mains and load range. This page synthesizes distributor pricing, lifecycle data, and practical design guidance for the TEA2376BT/1Y not consolidated in the manufacturer datasheet.

Its primary function is to level-shift logic-level PWM signals to the higher voltages required to fully enhance the power MOSFET, provide high peak current to rapidly charge and discharge the gate capacitance for fast switching, and protect the controller from the high-voltage switching transients present on the half-bridge. In the broader taxonomy, gate drivers belong to the power management family, sit alongside low-side drivers, high-side drivers, and isolated gate drivers, and serve as critical building blocks in motor-control, DC-DC, and inverter subsystems. Key features of the TLE7181EMXUMA1 include four independent half-bridge outputs capable of configuring as two full H-bridges, integrated charge pump for 100% duty-cycle high-side drive, programmable dead-time generation, short-circuit and over-current detection via dedicated current-sense comparator, under-voltage lockout (UVLO) on both VCC and VBS rails, overtemperature shutdown, and a serial peripheral interface (SPI) for fault read-back and configuration. The exposed thermal pad (PG-SSOP-24-4) provides a thermal resistance of approximately 31 C/W, allowing continuous operation at moderate switching frequencies in sealed automotive environments. Typical applications include brushed DC motor control in EPS systems, brushless DC (BLDC) motor pre-drivers, electric coolant and oil pumps, HVAC blower fans, transmission solenoids, and general-purpose automotive H-bridge inverters up to several hundred watts. A PWM/DIR interface allows direct connection to a microcontroller's timer peripherals for closed-loop current or speed control. The device's 12V support and integrated protection features reduce external component count, simplifying the design of ISO 26262-compliant motor drive subsystems. When designing with the TLE7181EMXUMA1, attention must be paid to PCB layout around the bootstrap capacitors, gate-drive loop minimization, and thermal management of the exposed pad. Designers should follow Infineon's reference design and application notes to achieve robust short-circuit detection and reliable operation across the automotive -40C to +150C temperature range.

The Infineon TLE7244SLXUMA2 is an 8-channel low-side power switch in PG-SSOP-24-7 package, delivering 290 mA per channel and designed specifically as a relay driver in automotive body and chassis applications. It operates from a supply range of 5 V to 28 V (3 V to 5.5 V logic supply), provides an SPI control and diagnostic interface, and offers four direct input pins for parallel control and PWM operation. Each of the eight outputs is protected against over-current, over-temperature, and short-circuit to ground and to battery. What is a low-side SPI relay driver? A low-side power switch is a type of power distribution IC that sits between the load (typically a relay coil, solenoid, or lamp) and ground, sinking current to switch the load on or off. When controlled by an SPI (Serial Peripheral Interface) link, a single microcontroller can manage many outputs with latched commands, while the driver handles the heavy current and protective functions locally. Low-side drivers belong to the broader category of power management ICs and, more specifically, intelligent load drivers / smart power switches used in automotive electronic control units. Key features of the TLE7244SLXUMA2 include eight open-drain N-channel outputs rated at 290 mA continuous, integrated protection with current limiting and thermal shutdown per channel, an SPI interface for diagnostics and configuration, four dedicated input pins for direct control or PWM generation, a limp-home function to maintain operation under microcontroller fault, and very low quiescent current in standby. The PG-SSOP-24-7 exposed-pad package provides excellent thermal dissipation and is qualified to Infineon's automotive reliability standards. Architecturally, the device pairs eight N-channel DMOS output stages with a digital control core that decodes SPI frames, drives fault flags, and arbitrates between direct-input and SPI commands. The embedded protective functions - over-current, open-load, over-temperature, and reverse battery - are designed to satisfy OEM body-controller module requirements, while the diagnostic word returned over SPI supports ISO 26262 functional-safety development at the system level. Typical applications include automotive body control modules driving relays and solenoids, junction box power distribution, lighting drivers (especially where PWM dimming is required), HVAC flap motors, and other inductive loads where protective switching and diagnostics are essential. The four input pins make it equally suitable as a stand-alone relay driver without MCU intervention during limp-home. When designing with this part, keep output flyback diodes or use relays with built-in freewheeling diodes because the low-side switch cannot clamp inductive kickback on its own. The exposed thermal pad must be soldered to a sufficient copper area on the PCB to keep junction temperature within ratings when driving multiple inductive loads simultaneously.

The device integrates a 16-bit SPI interface for channel control and diagnostic readback, supports 3 V cranking capability for cold-start automotive conditions, and provides a fail-safe (Limp Home) mode that maintains critical outputs when the microcontroller or SPI link fails. A low-side switch is a power distribution topology in which the MOSFET is placed between the load and ground, allowing the load to be tied to a permanent supply rail (e.g., the vehicle battery). This architecture belongs to the broader category of smart power switches (SPS), which combine a power transistor, gate driver, protection circuitry, and a digital diagnostic interface in a single IC. Smart low-side switches have largely replaced discrete MOSFETs + fuses in body electronics because they provide per-channel current limiting, overload shutdown, open-load detection, and thermal protection without external sense resistors. Key features of the TLE75004EPDXUMA1 include per-channel current limiting, open-load detection in both on and off states, over-temperature shutdown with auto-restart, short-to-ground and short-to-battery protection, and reverse battery protection via an external resistor. The SPI interface operates at clock rates up to 5 MHz, allowing fast update of output states and rapid polling of fault registers. An IDLE pin enables the Limp Home mode where input pins directly drive the outputs without SPI intervention. Typical applications include automotive body control modules (BCMs), door modules, seat controllers, and LED lighting drivers where multiple low-current relays, solenoids, or LEDs must be switched under microcontroller supervision. The PG-TSDSO-14-41 package provides an exposed thermal pad that keeps junction temperature low even when all four channels are delivering full current simultaneously. When designing with this part, ensure the SPI lines are pulled up to VCC and the IDLE pin is tied high for normal SPI-controlled operation.

A high-side switch (also called a smart power switch) is a semiconductor device that sits between a load and the positive supply rail. It replaces mechanical relays and discrete MOSFETs by combining a power transistor with protection, diagnostic, and communication circuitry. High-side switches sit in the family hierarchy: high-side switch -> power distribution switch -> power management IC -> semiconductor, and they enable centralized load control in body control modules, BCMs, and zonal architectures. Key features include 8 independently controlled channels, 16-bit SPI daisy-chain capability, integrated reverse-battery protection, open-load detection in on and off states, overtemperature shutdown with per-channel thermal sensors, and a Limp Home mode that allows safe operation at 3.0 V cranking transients. The device operates across a wide 4.5 V to 28 V supply range and withstands load-dump transients up to 40 V. The architecture uses N-channel MOSFETs with charge-pump-driven gates for true low-RDS(on) switching. Each channel includes current-limit set registers, individual fault flags, and PWM generation up to several hundred Hz. The exposed-pad package provides a thermal resistance below 30 C/W on standard 2 oz copper, supporting sustained 330 mA output per channel. Typical applications include automotive body electronics (lighting, HVAC blowers, seat control), industrial PLC relay drivers, and 24 V LED matrix modules. The combination of SPI diagnostics and cranking tolerance makes it well suited for 12 V automotive subsystems that must survive cold-crank events down to 3 V. When designing with this part, allocate PCB area for the exposed thermal pad and connect it to a solid copper pour. The Limp Home feature requires the SPI watchdog to be configured in the application firmware; an unconfigured watchdog defaults to fail-safe behavior. Per-channel current limit registers must be tuned to the load to avoid nuisance trips on inrush loads such as incandescent lamps or DC motors.

TLE75602ESHXUMA1 - 8-Ch SPI Power Switch 330mA | Infineon
The Infineon TLE75602ESHXUMA1 is an 8-channel low-side and high-side SPI-controlled power switch housed in a PG-TSDSO-24-21 package, delivering up to 330 mA per channel for 12 V automotive and industrial loads. Built on Infineon's SPIDER (Smart Power Integration Device with Embedded Regulation) technology, the device integrates eight MOSFET output stages, a 16-bit SPI interface, configurable PWM generators per channel, and comprehensive diagnostic features in a single exposed-pad thermally enhanced surface-mount package. An SPI-controlled power switch (sometimes called a multi-channel high-side switch, low-side switch, or smart solid-state relay) is a power-management IC that replaces discrete MOSFETs, fuses, and relay driver circuitry with an integrated, microcontroller-addressable load driver. It sits hierarchically as a child of power distribution switches, which themselves are a sub-family of power management ICs. By consolidating eight independently controllable outputs behind a serial-peripheral-interface (SPI) command set, the TLE75602-ESH eliminates dozens of discrete components while providing per-channel fault reporting, current monitoring, and PWM dimming that discrete implementations cannot match. Key features include an operating voltage range that supports 3.0 V cranking transients (typical 4.5 V to 28 V with load-dump survivability above this range), per-channel Rds(on) in the sub-200 mΩ class, integrated reverse-battery protection via an external resistor, programmable overcurrent shutdown, open-load detection in both on and off states, and overtemperature pre-warning and shutdown. The 16-bit SPI runs at clock rates up to 5 MHz and allows parallel operation of multiple TLE75602 devices for systems requiring more than eight channels. Architecturally, each of the eight channels combines an N-channel MOSFET output stage with charge pump, gate driver, current-sense amplifier, and fault logic. The on-chip diagnostic block can flag short-to-battery, short-to-ground, open load, and overtemperature events back to the host microcontroller through dedicated SPI status registers, enabling ASIL-aware functional-safety implementations under ISO 26262. Typical applications include automotive body controllers driving lamps, LEDs, relays, and small motors; zone-ECU load switching; industrial 24 V PLC discrete I/O; HVAC blower control; and centralized power distribution modules. The device's AEC-Q100 qualification and 3.0 V cranking capability make it well suited for cold-start conditions. When designing with this part, place at least one 100 nF decoupling capacitor close to the VCC pin and follow the PCB layout recommendations in the Infineon datasheet to keep the exposed thermal pad soldered for low RthJA. Always configure unused channels in a defined OFF state via SPI to avoid floating-output diagnostic noise.

It integrates a 5 V supply output, four low-side drivers, and an SPI control interface for small-engine and motorcycle ECU applications. According to Infineon's product page, the device accepts a wide 6 V to 40 V input voltage range, making it suitable for 12 V and 24 V automotive battery systems. Engine management PMICs are highly integrated power and driver ICs that combine a microcontroller-compatible supply rail, multiple low-side switches, communication interfaces, and protection features in a single package. They sit at the top of the small-engine ECU power tree, replacing discrete regulators plus discrete MOSFETs and reducing BOM count, PCB area, and quiescent losses. The TLE8082ES family is positioned in Infineon's TLE808x small-engine PMIC lineup. Key features include integrated 5 V linear or switching supply, four low-side driver outputs for injector or relay control, SPI-configurable diagnostics, and built-in protection such as thermal shutdown, overcurrent limiting, and reverse-battery robustness. The PG-TSDSO-24 exposed pad provides a thermal resistance path that supports sustained operation of the integrated drivers at engine ambient temperatures up to the AEC-Q100 automotive qualification envelope. Architecturally, the TLE8082ESXUMA1 combines an internal bandgap reference, a pre-regulator, a 5 V post-regulator, four gate drivers for low-side N-channel MOSFETs, and an SPI slave for microcontroller communication. This integration lets a small 32-bit MCU control fuel injection, ignition, and sensor power without auxiliary driver ICs. Typical applications include small-engine ECUs for motorcycles, scooters, mopeds, marine outboards, generators, and handheld power equipment. The wide VIN range and integrated drivers are tailored to single-cylinder and small-displacement powertrains where PCB area and BOM cost dominate the design. When designing with this part, ensure the exposed pad is soldered to a sufficient copper pour for thermal relief; sustained low-side driver currents can dissipate significant power. Use the SPI watchdog to detect MCU lockup, and follow Infineon's small-engine reference design for injector flyback sizing. This page synthesizes distributor stock, parametric specifications, design considerations, and drop-in alternatives that supplement the manufacturer datasheet.

It features a 16-bit Serial Peripheral Interface (SPI) for control, diagnosis, and configuration, plus comprehensive protection including over-current, over-temperature, over-voltage, and open-load detection. A multi-channel low-side driver IC is an integrated circuit that switches multiple resistive or inductive loads to ground using internal MOSFETs, controlled by a digital logic interface. Low-side drivers sit at the bottom of the load path (load connected to supply, switch to ground) and belong to the broader family of power distribution switches, motor/valve drivers, and powertrain switches used in automotive body and engine ECUs. Key features of the TLE9104SHXUMA1 include a 4.5 V to 28 V supply range, very low R_DS(on) per channel for high-efficiency switching, parallel-channel operation up to ~12 A, SPI-configurable dV/dt slew-rate control, and a 5 V VIO logic reference compatible with 3.3 V microcontrollers. The PG-DSO-20-88 exposed-pad package achieves a junction-to-ambient thermal resistance suitable for continuous 3 A per-channel operation with proper PCB copper area. The device is built on Infineon's SMART7 power technology with embedded protection state machine, providing deterministic fault handling required for ASIL-rated systems. The diagnostic block reports per-channel fault status, open-load, short-to-battery, and overtemperature flags through dedicated SPI registers. Typical applications include automotive engine-management loads (solenoid, valve, relay, injector drivers), transmission and gearbox control, body control modules, and 12 V / 24 V industrial switching. When designing, allocate at least 6 cm² of copper area to the exposed pad per channel of continuous current, and respect the SPI timing budget for sequential reads during fault scans.

The Infineon TLE9180D32QKXUMA1 is a multi-channel gate driver IC for six N-channel MOSFETs designed for 12 V, 24 V and 48 V brushless DC motor control in automotive environments. Housed in a PG-LQFP-64-27 (LQFP-64 with exposed pad) package, the part uses a high-voltage Smart Power technology that lets bridge, motor and supply pins withstand up to 90 V, while motor pins tolerate negative transients typical of inductive switching. The IC integrates three half-bridge drivers plus a charge pump, current-sense amplifier, and SPI diagnostics, making it a near-complete solution for 3-phase BLDC motor control. A gate driver IC (also called a MOSFET driver or predriver) is a power-management building block that translates low-current logic-level control signals from an MCU into the high peak currents required to rapidly charge and discharge a power MOSFET gate. In the system hierarchy, gate drivers sit between the microcontroller and the power stage: MCU -> gate driver -> power MOSFETs -> motor. Compared with discrete bootstrap drivers, an integrated multi-channel gate driver such as the MOTIX TLE9180D-32QK dramatically reduces BOM count, improves timing skew between high-side and low-side channels, and centralizes protection functions. Key features of this part include support for battery voltages from 5.5 V to 72 V, programmable gate drive currents up to 1 A source/sink, integrated current-shunt amplifier with adjustable gain, and ASIL-C functional safety support per ISO 26262.

The wide input range allows a single PCB design to support both 12 V passenger-vehicle platforms and 48 V commercial-vehicle or mild-hybrid systems, reducing platform SKU count for tier-1 suppliers.
TLF11251EPXUMA1 - 2.5A Half-Bridge Gate Driver | Infineon
The Infineon TLF11251EPXUMA1 is an integrated half-bridge gate driver capable of sourcing/sinking 2.5 A, designed for OPTIREG PMIC TLF35584/85 pairing with AURIX TC38x/TC39x 32-bit microcontrollers. Housed in a 14-pin PG-TSDSO-14-5 package, the device drives a PMOS/NMOS output stage with non-inverting logic and a wide 2.35 V to 7 V supply input. The combination of 60 ns typical propagation delay and 2.5 A peak drive makes it the companion driver for the core voltage rails of high-end 2nd-generation TriCore AURIX microcontrollers. A half-bridge gate driver is a power-management building block that combines a high-side and a low-side MOSFET driver in one IC, translating low-current PWM logic signals from a controller into the high-current gate drive required to switch power MOSFETs or, in this case, a PMOS/NMOS bridge. Within the broader IC taxonomy, this places the part in the gate-driver sub-family of power management ICs, itself a subset of PMIC and analog mixed-signal semiconductors. Half-bridge drivers are commonly used as core-supply pre-regulators or post-regulators next to multi-rail PMICs. Key features include 2.5 A peak gate-drive current, 60 ns propagation delay, non-inverting input logic, and 2.35 V to 7 V supply operation. The PG-TSDSO-14-5 thermally-enhanced small-outline package provides a low thermal resistance path for the high peak currents encountered during MOSFET switching transitions, while the non-inverting interface simplifies PWM routing from the host controller. Internally, the TLF11251EP combines a PMOS high-side path and an NMOS low-side path with adaptive drive strength and protection features. The 2.5 A capability allows it to switch large PMOS/NMOS bridges quickly, reducing switching losses and improving transient response on the AURIX core supply rail. The OPTIREG product family designation confirms Infineon qualification for safety-relevant automotive power architectures. Typical applications include AURIX TC38x/TC39x core supply pre-regulation, OPTIREG TLF35584/85 PMIC companion drivers, automotive 12 V ECU power trees, and industrial 24 V buck/boost pre-drivers. The wide supply range and high drive strength also make it suitable as a general-purpose PMOS/NMOS half-bridge in 5 V and 12 V distributed power systems. When designing with this device, observe the absolute maximum supply rating of 7 V and provide a local 100 nF + 1 µF decoupling network directly at the VCC pin. Keep the gate-drive traces short and width-matched to limit parasitic inductance, which can otherwise cause ringing on the PMOS/NMOS gate that may violate the AURIX core supply tolerance window.
TLF11251LDXUMA1 - 2.5A Half-Bridge Gate Driver for AURIX | Infineon
The Infineon TLF11251LDXUMA1 is a 2.5 A half-bridge gate driver IC housed in a 10-pin PG-TSON-10-2 (exposed pad) package, designed as a companion driver for the OPTIREG PMIC TLF35584/85 in automotive ECU power architectures. The part uses a PMOS/NMOS output stage that delivers 2.5 A peak source/sink current with 60 ns typical rise and fall times, enabling fast switching of power MOSFETs in 12 V automotive battery rails. A half-bridge gate driver is a power-management IC that translates low-current logic-level PWM signals from a microcontroller into the high-current gate-drive signals required to switch the high-side and low-side MOSFETs of a synchronous buck or boost converter. In the broader power-management hierarchy, the TLF11251 sits between the microcontroller (control layer) and the discrete power MOSFETs (switching layer), making it a critical glue device in DC-DC converter sub-systems. Without a dedicated driver, a microcontroller GPIO pin cannot directly charge and discharge a power MOSFET gate fast enough for efficient high-frequency switching. Key specifications include a 3.5 V to 7 V supply range, 2.5 A peak output drive, 60 ns propagation delay matching between high-side and low-side channels, and integrated shoot-through protection that prevents both MOSFETs from conducting simultaneously. The non-inverting input logic simplifies PWM signal routing, and the exposed thermal pad keeps junction temperature low during continuous switching. The driver is qualified to AEC-Q100 for automotive under-hood and chassis applications. The TLF11251 is specifically engineered to pair with Infineon's AURIX TC38x and TC39x 32-bit TriCore microcontrollers, providing the gate-drive stage for downstream buck converters that power the MCU core, ADC, and communication peripherals. The tight propagation-delay matching supports the dead-time control required by the OPTIREG TLF35584/85 PMIC family. Internal shoot-through protection and under-voltage lockout (UVLO) on the driver supply safeguard the power stage during cold-crank and load-dump transients typical of 12 V automotive electrical systems. Typical applications include 12 V automotive DC-DC converters, AURIX TC38x/TC39x ECU power stages, body-control modules, ADAS sensor power rails, and industrial 24 V buck regulators. The 2.5 A drive strength is sufficient for switching most sub-100 V N-channel MOSFETs commonly used in point-of-load converters up to approximately 10 A load. When designing with this part, place the bootstrap capacitor for the high-side channel as close as possible to the BST and SW pins to minimize switching losses. The exposed pad must be soldered to a sufficiently large copper pour to keep junction temperature within the -40 C to +125 C automotive grade-A operating range.

TPS2054 - Quad 0.5A USB Power Switch 80mOhm | Texas Instruments
The Texas Instruments TPS2054 is a quad-channel power-distribution switch integrating four N-channel MOSFET high-side switches in a single 16-pin SOIC package. Each channel supports 500 mA continuous current with a 0.9 A current limit, operating from a 2.7 V to 5.5 V input range with 80 mOhm maximum on-resistance (5 V input) and active-high enable inputs. A power-distribution switch is a type of load switch within the power management IC hierarchy that sits between a supply rail and its load, providing controlled turn-on, fault protection, and status reporting. USB power switches specifically guard downstream ports against overcurrent and short-circuit faults, preventing host rail collapse in systems that distribute 5 V power to multiple peripheral ports. Key features include 500 mA continuous current per channel for USB compliance, 135 mOhm typical high-side MOSFET resistance, short-circuit and thermal protection, and an overcurrent logic output (nFAULT) that signals fault conditions to the host controller. The device offers logic-level enable inputs, a 2.5 ms typical output rise time that limits inrush current during hot-plug events, and undervoltage lockout for predictable startup behavior. Internally, each switch uses a charge-pumped N-channel MOSFET gate drive with precision current-sense circuitry. When load current exceeds the 0.9 A limit, the device enters constant-current mode; sustained faults trigger thermal shutdown per channel. The open-drain overcurrent output allows direct connection to a microcontroller GPIO with a pull-up resistor. Typical applications include USB hub port power control, self-powered and bus-powered USB peripherals, multi-port charging accessories, hot-plug power switching in embedded systems, and industrial power-rail partitioning requiring per-channel fault isolation. Design tip: the controlled 2.5 ms rise time removes the need for external soft-start circuitry, but ensure PCB traces per channel are rated for 0.9 A fault current and place the input/output bypass capacitors close to the device pins for stable current-limit behavior.
TPS2054AD - Quad 500mA USB Power Distribution Switch | TI
The Texas Instruments TPS2054AD is a quad-channel current-limited power-distribution switch integrating four 80 mOhm N-channel MOSFET high-side switches, delivering 500 mA continuous current per channel (0.9 A minimum current limit) from a 2.7 V to 5.5 V input range in a 16-pin SOIC (D) package. A power-distribution switch, also called a high-side load switch or USB power switch, is a power management IC that sits between a supply rail and a load, turning the load on and off with a logic-level enable signal while protecting the upstream supply from faults. Within the power management hierarchy, it belongs to the power-distribution switch and load-driver class, complementing voltage regulators and hot-swap controllers in multi-port systems. Key features include independent enable inputs (CMOS- and TTL-compatible, active-high) for each channel pair, a per-channel current limit with independent thermal and short-circuit protection, and a shared fault-report logic output that flags overcurrent conditions to a host controller. A 2.5 ms typical output rise time limits inrush current when switching heavy capacitive loads, and undervoltage lockout keeps the outputs off until the input rail is valid. Architecturally, each N-channel MOSFET switch is driven by an internal charge-pump gate driver, which keeps on-resistance low at only 80 mOhm and minimizes voltage drop at full 500 mA load. Response to short circuits is fast, protecting the input rail from brownout during fault events. Typical applications include USB host and hub port power switching, hot-plug power distribution in set-top boxes and peripherals, and multi-rail power sequencing in industrial systems where heavy capacitive loads and short circuits are likely. A key design consideration: at 5.5 V input and full load on all four channels, estimate conduction loss as 4 x I^2 x RDS(on) = 4 x 0.25 x 0.08 = 80 mW (estimated), which the SOIC-16 package dissipates without a heatsink, but PCB copper around pins still aids thermal relief. This page adds value beyond the manufacturer datasheet by synthesizing distributor pricing, drop-in same-brand alternatives (TPS2054BD, TPS2054DG4), and practical design notes for power-distribution switching designs.
TPS2062CDGNR - Dual 1A USB Power Switch | Texas Instruments
The Texas Instruments TPS2062CDGNR is a dual-channel, current-limited, power-distribution switch designed for USB and other hot-swap applications where heavy capacitive loads and short-circuits may be encountered.

The device operates over an input voltage range of 2.7V to 5.5V and supports a continuous load current of 1A per channel, with a fixed current-limit threshold of 1.5A (typical) and an accurate ±20% current-limit tolerance. A power-distribution switch is a type of load switch that provides controlled power delivery to downstream circuits, offering protection against overcurrent, short-circuit, and over-temperature conditions. It sits between the power source and the load, acting as a smart switch that can be enabled or disabled via a control signal. In the system hierarchy, a power-distribution switch is a subset of power management ICs, which also include voltage regulators, DC-DC converters, and battery management devices. The TPS2062C family is specifically optimized for USB ports, where it ensures safe power delivery and protects the host controller from fault conditions. Key features of the TPS2062CDGNR include a fast overcurrent response time of 2 µs (typical), which quickly limits fault current to protect upstream components. The device also provides reverse current blocking, output discharge function, soft-start to reduce inrush current, and under-voltage lockout (UVLO) to ensure proper operation during power-up. Built-in over-temperature protection and short-circuit protection further enhance system reliability. The active-low enable inputs allow for simple logic control, and the 70-mΩ on-resistance minimizes power loss and voltage drop across the switch. Technically, the TPS2062CDGNR uses a constant-current limiting scheme that maintains a safe output current during overload conditions, preventing damage to the switch and the load. The output discharge function actively pulls the output to ground when the switch is disabled, ensuring no residual voltage remains on the load. The soft-start feature limits inrush current when driving capacitive loads, which is critical for USB applications where downstream capacitors can be large. The device is specified for operation over the industrial temperature range of -40°C to +125°C, making it suitable for a wide range of environments. Typical applications include USB ports on computers, hubs, and peripherals, as well as general-purpose power switching in consumer electronics, industrial equipment, and set-top boxes. The dual-channel configuration allows two independent loads to be controlled from a single device, saving board space and cost. The TPS2062CDGNR is also ideal for powering downstream devices in systems that require hot-swap capability, such as docking stations and battery chargers. When designing with this device, ensure that the input and output capacitors are placed close to the pins to minimize parasitic inductance and maintain stable operation. The exposed thermal pad should be soldered to a large copper area on the PCB to enhance heat dissipation, especially when operating at high currents. Additionally, the enable pins should be driven with proper logic levels to avoid unintended switching.
TPS2062DR - Dual 1A USB Power Switch | Texas Instruments
The Texas Instruments TPS2062DR is a dual-channel, current-limited power distribution switch designed for USB and general-purpose power management applications. It integrates two 70-mΩ high-side N-channel MOSFETs, each capable of delivering up to 1 A continuous current, with an input voltage range of 2.7 V to 5.5 V. The device is housed in an 8-pin SOIC (D) package and features an active-low enable input, making it suitable for power sequencing and hot-swap applications. A power distribution switch is a semiconductor device that controls and protects power delivery to downstream loads. It typically includes a high-side MOSFET, current sensing, and protection features such as overcurrent, thermal shutdown, and undervoltage lockout. In a system hierarchy, the TPS2062DR sits between the main power rail and peripheral devices, acting as a smart switch that can be turned on/off via a logic signal while providing fault protection. Key features of the TPS2062DR include a 70-mΩ high-side MOSFET, 1-A continuous current per channel, accurate current limit (1.1 A min, 2.1 A max), thermal and short-circuit protection, undervoltage lockout, deglitched fault report (OC), and a typical rise time of 0.6 ms. The active-low enable input allows for straightforward control from microcontrollers or logic gates. The device operates over a junction temperature range of -40°C to 125°C, making it suitable for industrial and automotive environments. Technically, the TPS2062DR uses a current-limited architecture that ensures safe operation under overload conditions. The accurate current limit prevents excessive current draw, protecting both the switch and the load. The deglitched fault report (OC) provides a clean signal to the host controller, avoiding false triggers from transient currents. The undervoltage lockout ensures the switch remains off until the input voltage is stable, preventing erratic behavior during power-up. Typical applications include USB port power switching, hot-swap power distribution, and power management in consumer electronics, industrial equipment, and networking devices. The dual-channel configuration allows independent control of two loads, making it ideal for applications requiring multiple power domains. When designing with the TPS2062DR, ensure adequate input and output capacitance to maintain stability and minimize voltage transients. Place the device close to the load to reduce parasitic inductance and improve fault response. The active-low enable pin should be pulled up or driven by a logic signal; do not leave it floating.
TPS22997QRYZRQ1 - 10A, 5.5V Load Switch | Texas Instruments
The Texas Instruments TPS22997QRYZRQ1 is an AEC-Q100 qualified single-channel automotive load switch delivering up to 10A continuous current over an input voltage range of 0.1V to 5.5V, with a bias supply of 1.5V to 5.5V. It integrates an N-channel MOSFET with a typical on-resistance of only 4 mΩ in a compact 10-pin WQFN-HR (RYZ) package measuring just 1.5 mm x 2 mm. A load switch is a power management IC that gates a power rail on and off using an integrated MOSFET controlled by a logic-level enable pin. In the power management hierarchy, load switches sit between the power source (a DC-DC converter or LDO) and the load, providing controlled power-up sequencing, inrush limiting, rail isolation, and fault protection that raw converters do not offer. Key features include adjustable slew-rate control to minimize inrush current during turn-on, an adjustable quick output discharge (QOD) pin that actively pulls the output low when disabled, and a power-good output for rail monitoring and sequencing. The ON pin can interface directly with low-voltage GPIO signals. Thermal shutdown and low quiescent power consumption round out the feature set. Technically, the 4 mΩ RON translates to only 40 mV of drop at 10A and just 0.4W of conduction loss, eliminating the need for a heatsink. The configurable rise time allows designers to trade startup time against inrush current to protect upstream regulators and downstream capacitors. Typical applications include automotive ADAS processor and FPGA power sequencing, infotainment rail gating, sensor module power control, and battery-connected load management in 5V and sub-5V systems. The Q1 qualification supports all AEC-Q100 automotive ambient temperature grades. Design tip: use the CT pin capacitor to set slew rate so that inrush into large downstream bulk capacitance stays within the upstream supply current limit, and verify bias voltage is present before asserting ON.
