The MC13892VK uses a programmable architecture based on a hardware state machine augmented by an I2C interface, allowing designers to tailor output voltages, sequencing order, fault behavior, and charger parameters to the specific i.MX platform. On-chip ADC inputs monitor battery, current, and die temperature for accurate fuel gauging and thermal management across the -40C to +85C industrial range. Typical applications include portable / handheld terminals, industrial HMI panels, single-board computers, point-of-sale devices, mobile medical electronics, and any i.MX35 or i.MX51-based product needing a compact, fully integrated power tree. The 139-PBGA 7x7 mm package reduces board area by eliminating multiple discrete regulators. For board layout, place input and output ceramic capacitors as close as possible to the buck and LDO pins to minimize switching-node ringing and reduce EMI. Ensure the thermal pad is tied to a continuous ground plane with sufficient vias to support peak battery-charger dissipation.

MC13892VL - 5/28V PMIC for i.MX | NXP Semiconductors
The NXP Semiconductors (formerly Freescale) MC13892VL is a highly integrated 5 V/28 V buck/boost Power Management and User Interface IC (PMUIC) designed as a companion chip for the NXP i.MX51, i.MX37, i.MX35, i.MX27 application processors. It is housed in a 186-pin LFBGA (12x12 mm) package and targets handheld, battery-powered mobile platforms. What is a PMIC? A Power Management Integrated Circuit (PMIC) is a single-chip regulator that consolidates multiple DC-DC converters, LDOs, charge controllers, and power-sequencing logic into one device, simplifying portable designs by replacing dozens of discrete components and enabling programmable multi-rail start-up. PMICs sit in the power management hierarchy above discrete voltage regulators, and below the SoC they supply, acting as the intelligent power backbone for an application processor. The MC13892VL provides a programmable buck switching regulator core for the processor Vcore, multiple LDOs for peripherals, a USB-OTG compliant boost, an LED driver array, a touch-screen interface, a 10-bit ADC for battery monitoring, and an SPI/I2C interface for host control. According to the manufacturer datasheet, it directly supports the power-rail requirements of the i.MX51 family with hardware-programmable output voltages and sequence timing. Although the device is now classified as EOL (End of Life), it remains valuable as a reference design for legacy i.MX-based smartbooks, eBooks, portable navigation systems, smartphones, and ultrasound medical equipment. The wide 5 V to 28 V input range covers both single-cell Li-ion USB supplies and 2-cell industrial battery stacks, making it attractive for tablet and rugged-handheld use cases. Designers integrating this part should verify the latest NXP product-change notifications and consider the pin-compatible MC13892JVL variant or newer PF0100 series for new designs.

The NXP MC13892VLR2 is a power management unit (PMU) companion IC designed to power NXP's i.MX51, i.MX37, i.MX3, and i.MX27 application processors in a 186-pin LFBGA (12x12) package. It integrates multiple buck and boost switching regulators along with linear regulators, LED drivers, battery charging, and a real-time clock supply, delivering a complete system power solution from a single IC. A power management IC (PMIC/PMU) is a highly integrated mixed-signal device that consolidates the multiple voltage rails required by an application processor and its peripherals into one package. The PMIC sits between the battery or DC adapter and the SoC, replacing dozens of discrete DC-DC converters and LDOs with a programmable, sequencable solution that improves efficiency, reduces PCB area, and simplifies power-up sequencing. Within the broader taxonomy, the MC13892 belongs to the application-processor-specific PMIC class, sitting between general-purpose multi-rail PMICs and discrete point-of-load regulators. Key features of the MC13892VLR2 include four synchronous buck converters operating from a 5V/28V input range, multiple LDO outputs, a backup battery charger, programmable startup sequencing via I2C, and integrated LED drivers for display backlighting. The device supports dynamic voltage scaling (DVS) to extend battery life in portable applications by adjusting core voltages to match processor load. According to NXP product documentation, the part targets handheld and mobile devices such as personal media players and GPS navigation units. The MC13892 uses a mixed-signal architecture combining hysteretic and PWM buck controllers with linear post-regulators, optimized for fast transient response to the variable loads created by modern application processors. Its I2C-programmable output voltages and enable timing allow seamless co-design with the i.MX51/37/35/27 power-on sequence, eliminating the need for external sequencer logic. Typical applications include portable media players, GPS navigation devices, handheld industrial terminals, and other battery-powered embedded systems based on the supported i.MX processors. The wide input voltage range (5V to 28V boost-capable) also enables designs powered from multi-cell battery packs or 12V automotive rails. When designing with the MC13892VLR2, pay close attention to the 186-ball LFBGA layout - controlled-impedance routing is needed for the high-current buck inductor nodes. Thermal management requires adequate copper under the exposed die area because the internal MOSFETs dissipate several hundred milliwatts to several watts depending on load and input/output voltage differential. This page synthesizes distributor stock levels, package-level alternative equivalents, and application reference designs that go beyond the bare datasheet, helping engineers source, second-source, and qualify the MC13892VLR2 more efficiently.
MC14489BDWE - 5-Channel LED Display Driver, CMOS | NXP
The NXP MC14489BDWE is a CMOS multi-character LED display/lamp driver that interfaces directly to individual lamps, 7-segment displays, or combinations of both, packaged in a 20-pin SOIC (SOG-20) with 7.5 mm body width. The device supports 15 high-level outputs at 5.4 V / 17.5 mA with multiplexed-by-5 common-cathode LED driving across 4.5 V to 5.5 V supply rails. Communication with an MCU/MPU is established through a synchronous serial port, retaining display data between updates to minimize host overhead. An LED display driver is a type of display driver IC that converts serial or parallel data from a microcontroller into the time-multiplexed current waveforms required to illuminate discrete LEDs, 7-segment numerals, or dot-matrix arrays. The MC14489BDWE sits in the broader hierarchy of display driver -> PMIC (Power Management IC) -> semiconductor, providing a single-chip bridge between low-power logic and the higher-current requirements of LED clusters. By integrating the multiplex scan, segment decoding, and constant-current sinks, the part removes discrete transistor arrays and reduces MCU pin count. Key features include five digit/character driver outputs (a, b, c, d, e) sourcing up to 17.5 mA per segment, fifteen programmable low-side sink paths supporting common-cathode topologies, and a synchronous serial interface (clock, data, enable) for daisy-chain expansion. The device provides non-volatile display retention via on-chip latches, eliminating flicker between MCU writes, and supports per-character brightness control through duty-cycle modulation of the multiplex scan. The MC14489BDWE is built on a mature CMOS process, drawing minimal quiescent current from the 4.5 V to 5.5 V supply. The multiplexed-by-5 architecture reduces external wiring: one MC14489BDWE drives five 7-segment digits with only six signal lines (five digit selects plus segment bus), versus the dozens of discrete lines a static-drive design would require. This makes the part especially attractive for legacy industrial HMIs and cost-sensitive consumer appliances. Typical applications include numeric LED readouts on white goods, industrial control panels, point-of-sale terminals, instrumentation displays, and automotive dashboard sub-assemblies. It is also used in status indicator stacks where five discrete lamps convey machine state without requiring a full alphanumeric display. When designing with the MC14489BDWE, observe the 5.5 V absolute-maximum supply rating and provide adequate bulk decoupling near the VCC pin. The serial interface timing must respect the datasheet's setup-and-hold margins to avoid display corruption. For multi-character strings exceeding five digits, cascade additional MC14489B devices via the serial-enable line. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, providing a single reference for engineers evaluating LED driver replacements for legacy NXP/Motorola designs.

Typical applications include i.MX 7-series and i.MX RT wearable platforms, Bluetooth/Zigbee/LoRa IoT sensor hubs, smart-home controllers, portable medical monitors, and low-power industrial IoT gateways. When designing in the PF1510, follow NXP's reference schematic and PCB layout guidelines, paying particular attention to the exposed pad soldering, input bulk-capacitor placement, and the I2C pull-up values to ensure robust PMIC-to-SoC communication.
MC32PF3000A4EP - i.MX7 PMIC, 4 Buck + 1 Boost + 6 LDO | NXP
The NXP Semiconductors MC32PF3000A4EP is a configurable Power Management Integrated Circuit (PMIC) targeting NXP i.MX7 and i.MX6 application processors, integrating 4 buck converters, 1 boost regulator, and 6 LDOs in a single 48-pin QFN (7x7 mm) package with exposed thermal pad. The PMIC is pre-programmed for i.MX7 application processor use and operates from a 2.8V to 5.5V supply input. A PMIC (Power Management Integrated Circuit) is a highly integrated device that consolidates multiple voltage rails, sequencing logic, and supervisory functions for a host processor. Positioned in the system power hierarchy, a PMIC sits between the battery or DC input and the application processor's internal voltage domains. The PF3000 specifically targets battery-powered and low-power applications, providing dynamic voltage scaling (DVS) controlled through an I2C interface to extend battery life on i.MX 6DualLite and i.MX 7-series single-core Cortex-A processors. Key features of the MC32PF3000A4EP include 4 buck converters, 6 LDOs, one boost regulator, an integrated Coulomb counter for battery fuel gauging, and I2C programmability for output voltage, sequencing, and fault behavior. The device supports software-controlled dynamic voltage scaling, allowing the host processor to lower its core voltage during periods of light load. Operating temperature range spans -40C to +85C industrial grade. Architecturally, the PF3000 uses a programmable state machine and OTP (one-time programmable) memory to set default rail voltages, sequence timing, and protection thresholds without external component overhead. Built-in supervisory functions include under-voltage, over-voltage, over-current, and thermal shutdown protection. A built-in watchdog timer and reset generator reduce the bill of materials for processor companion circuits. Typical applications include i.MX7 and i.MX 6DualLite portable handheld terminals, industrial HMI panels, wearables, portable medical devices, point-of-sale terminals, and low-power IoT edge gateways. The integrated fuel gauge and DVS capability make the part especially attractive for battery-powered designs where every milliamp matters. When designing with the MC32PF3000A4EP, follow the NXP reference design schematic closely and use the supplied OTP configuration to ensure proper i.MX7 boot sequencing. Note that the part ships as a consumer-grade variant; for AEC-Q100 automotive qualification, review the MC33PF3000A5ES or MC34PF3000A5EP variants from the same family. This page synthesizes NXP PF3000 family datasheet specifications, drop-in alternate parts verified against the same QFN-48 footprint, and a practical design notes set not aggregated in any single manufacturer document.
MC32PF3001A3EP - PF3001 PMIC for i.MX7, 3 Buck + 6 LDO | NXP
The NXP MC32PF3001A3EP is a Power Management IC (PMIC) purpose-built for the NXP i.MX 7 application processor family, integrating 3 buck (step-down) regulators, 6 LDO regulators, and an always-on domain in a single 48-pin QFN (7x7 mm) exposed-pad package. The device is pre-programmed with the i.MX 7 power sequence and output voltages, eliminating the need for external OTP programming. According to the NXP PF3001 datasheet, the input supply range is 2.8 V to 5.5 V (typically powered from a USB or 1S Li-ion source after a buck boost), and the IC operates over the industrial -40 °C to +85 °C range. A PMIC (Power Management Integrated Circuit) is a specialized class of power-management IC that consolidates multiple voltage rails - typically buck switching converters, low-dropout (LDO) linear regulators, and always-on housekeeping supplies - into a single silicon die. PMICs sit at the top of the power-management hierarchy (PMIC > multi-rail regulator > DC-DC converter + LDO > discrete regulators) and are most often paired with a host processor to reduce BOM count, PCB area, and design time. Compared with discrete power designs, a PMIC also embeds sequencing logic that ensures the host processor's core, memory, and I/O rails come up in the correct order, avoiding latch-up or in-rush faults. Key features of the PF3001 include: 3 synchronous buck converters with output currents up to 3 A, 2750 mA and 1500 mA on SW1/SW2/SW3 respectively; 6 general-purpose LDOs from 100 mA to 500 mA; a low-power always-on LDO/counter for RTC and wake-up; I²C interface for dynamic voltage scaling and fault monitoring; OTP-programmed defaults targeting i.MX 7 power trees; and full protection: over-voltage, under-voltage, over-current, thermal shutdown, and input power-good. The exposed pad keeps the junction-to-ambient thermal resistance low for high-current rails. Architecturally, the PF3001 uses a 1.5 MHz peak-current-mode buck topology that allows small inductors and ceramic-only output capacitors. The 6 LDOs share a common reference and tracking block; the always-on block is powered directly from VSYS so it survives main rail shutdown for RTC and wake-event monitoring. The IC communicates over a standard 100/400 kHz I²C bus and exposes a mask-able interrupt pin to the host processor. Typical applications include i.MX 7 / i.MX 6SoloLite / SoloX / UltraLite based portable medical tablets, IoT gateways, wearables, point-of-sale terminals, industrial HMI panels, and low-power IoT edge nodes. The wide Vin range also makes it usable in USB-powered designs. When designing with the PF3001, the designer should allocate a substantial ground copper pour under the exposed pad and route the 3 switching-node traces with short, wide loops to limit EMI. The I²C lines require pull-ups to the always-on rail so configuration is preserved across sleep. The OTP defaults target i.MX 7; for i.MX 6 variants the engineer must verify many parameters in software or migrate to a sibling part in the PF300x family. This page synthesizes distributor pricing, drop-in alternative PMICs (PF3000, PF8100/PF8200 family variants), and PCB layout/design notes not found in the standalone datasheet, giving the engineer a single-source reference for the MC32PF3001A3EP and its drop-in NXP-family replacements.
MC33063AD - 1.5A Buck/Boost/Inverting DC-DC Converter | Texas Instruments
The Texas Instruments MC33063AD is a monolithic switching regulator IC containing all primary functions required for building simple DC-DC converters in buck, boost, and inverting topologies. Housed in an 8-pin SOIC (D) package with 3V to 40V input voltage range, the MC33063AD integrates a temperature-compensated 1.25V reference, a comparator, a duty-cycle-tunable oscillator up to 100 kHz, an active current-limiting PWM controller, a driver, and a high-current 1.5A Darlington output switch. It is specified over the -40C to +85C industrial operating temperature range. A switching regulator is a power management IC that converts one DC voltage to another by repeatedly switching energy through an inductor, then filtering with capacitors. The MC33063AD belongs to the SMPS controller family (switched-mode power supply) -> DC-DC converter -> voltage regulator -> power management IC -> semiconductor. Compared to linear regulators, switching converters like the MC33063AD achieve 70-95% efficiency even at large input-to-output voltage deltas, making them ideal when thermal dissipation must be minimized or when the input voltage is much higher than the output. Key features include a 1.5A peak switch current rating, an adjustable output voltage down to 1.25V, internal current limiting via a single external resistor, and an external resistor-programmable oscillator frequency from approximately 100 Hz to 100 kHz. The 8-SOIC package provides standard surface-mount manufacturability and is footprint-compatible with the MC34063A (commercial 0-70C) and MC33063ADG (onsemi second source). Architecturally, the device uses a bipolar Darlington output switch, a transconductance error amplifier referenced to the internal 1.25V bandgap, and a flip-flop synchronized to the on-chip oscillator. This classic 1970s architecture remains popular because the design requires only a handful of external parts (inductor, capacitor, diode, sense resistor, feedback divider) and provides predictable behavior across a wide input range. Typical applications include cost-sensitive step-down converters for 12V/24V industrial buses, boost converters for battery-powered systems needing 5V or higher rails, and negative-voltage inverters for op-amp and analog signal-chain supplies. The internal switch and current limit also make it suitable for LED drivers and simple motor speed controllers operating from single-cell Li-ion or multi-cell lead-acid sources. When designing with the MC33063AD, ensure the inductor saturation current exceeds the internal current-limit threshold, and verify that the catch diode reverse voltage rating exceeds the maximum input supply. PCB layout should keep the switch-current loop (pin 1, inductor, catch diode) compact to minimize switching noise. This page synthesizes distributor pricing, drop-in alternatives from TI and onsemi, and practical design notes not consolidated in the manufacturer datasheet.
MC33063ADG4 - 1.5A Buck/Boost/Inverting Switching Regulator | TI
The Texas Instruments MC33063ADG4 is a monolithic DC-DC switching regulator controller IC rated for 1.5 A peak switch current, supporting buck, boost, and inverting topologies in an 8-pin SOIC package. It integrates a temperature-compensated 1.25 V reference, a duty-cycle-controlled oscillator (up to 100 kHz), a comparator, an active current-limit circuit, a driver, and a high-current output switch on a single die. The wide 3 V to 40 V input range and adjustable 1.25 V to 40 V output make it a versatile single-chip solution for non-isolated point-of-load conversion. A switching regulator is a power-conversion IC that uses an energy-storage element (inductor or transformer) and a switching transistor to transfer energy from input to output at high efficiency, unlike a linear regulator which dissipates the VIN-VOUT differential as heat. The MC33063 family belongs to the SMPS (Switched-Mode Power Supply) controller hierarchy: switching regulator -> DC-DC converter -> power management IC. Within that hierarchy, the MC33063 occupies the 'all-in-one controller + internal switch' tier that lets engineers build a complete converter with a handful of external passive components and one Schottky rectifier. Key features include a 2% internal reference, 100 kHz maximum oscillator frequency, short-circuit protection via the current-sense comparator, and a guaranteed 1.5 A output switch. The exposed thermal pad (DAP) on the SOIC-8 package lowers thermal resistance versus a standard SOIC-8, allowing continuous operation near the 1.5 A switch limit at moderate ambient temperatures. The same silicon die is offered across the MC33063 (industrial -40C to +85C), MC34063 (commercial 0C to +70C), and MC33063A (extended voltage tolerance) families, giving designers direct drop-in migration paths. The architecture is built around a current-mode control loop: the internal comparator monitors the output voltage via a resistor divider, the oscillator sets the switching period, and the on-time is modulated to keep VOUT in regulation. The integrated Darlington output switch drops about 1.5 V at full load, so for 5 V outputs from a 12 V rail, efficiency reaches roughly 80 percent. Compared with newer TI WEBENCH-targeted controllers, the MC33063 is a low-cost, well-documented legacy part that remains in service due to its simplicity, broad input range, and second-source availability. Typical applications include non-isolated point-of-load converters in industrial controls, 24 V to 5 V auxiliary rails in factory automation, negative bias supplies for op-amps and LCDs, battery chargers with current limiting, and distributed 12 V buss regulators in telecom and automotive subsystems. Its 40 V input tolerance also suits automotive load-dump-protected rails. When designing with this part, select the timing capacitor CT to set the oscillator near 30-50 kHz for typical buck or boost designs; lower frequencies improve efficiency but require larger inductors. Place the catch diode and inductor close to the switch pin to minimize parasitic inductance, and use a low-ESR output capacitor to limit ripple. The current-sense resistor RS determines peak switch current and therefore the converter's load capability. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in a single manufacturer document.
MC33063ADR - 1.5A Buck/Boost/Inverting Switching Regulator | TI
The Texas Instruments MC33063ADR is a 1.5 A peak switching regulator controller IC implementing all primary functions needed for step-down (buck), step-up (boost), and inverting DC-DC converters in a single 8-pin SOIC package. The device operates from a 3 V to 40 V input range, delivers an adjustable output voltage from 1.25 V to 40 V, and supports switching frequencies up to 100 kHz, addressing cost-sensitive industrial, automotive, and consumer power designs. An SMPS controller (switched-mode power supply controller) is an IC that drives an external power switch (typically a BJT or MOSFET) at a programmed duty cycle to convert one DC voltage to another. The MC33063A family belongs to the SMPS controller -> DC-DC converter -> power management IC hierarchy, and is among the longest-lived TI part numbers, serving as a baseline for thousands of cost-optimized designs since its original bipolar 34063 release. Key features include a precision 2 % internal bandgap reference, duty-cycle-controlled pulse-width modulator, internal current limiting, and an internal output switch rated at 1.5 A peak. The adjustable output uses a single external resistor divider, and the oscillator timing capacitor sets the switching frequency. The integrated switch and short-circuit protection simplify BOM count to as few as five external components. Architecture-wise, the MC33063ADR combines a temperature-compensated reference, a duty-cycle comparator, an oscillator with active-high output, a current-limit comparator with 250 mV threshold, and a Darlington output driver. The bipolar process delivers robust SOA but at lower efficiency than CMOS alternatives, making the part best suited to moderate-power applications rather than battery-critical portable loads. Typical applications include non-isolated point-of-load converters, 12 V to 5 V automotive accessory rails, LCD bias supplies, and simple inverting supplies for op-amp negative rails. The wide 3 V-40 V input range allows direct connection to industrial 24 V buses. When designing with this device, choose inductor value to keep peak switch current below 1.5 A and use a Schottky catch diode to maximize efficiency. The timing capacitor CT should be selected to keep switching frequency between 30 kHz and 100 kHz to balance efficiency and EMI. This page synthesizes distributor pricing, drop-in pin-compatible alternatives, and practical design notes not consolidated in the manufacturer datasheet, providing an AEO-optimized reference for engineers sourcing the MC33063ADR.
MC33262PG - CRM PFC Controller, 12-28V | onsemi
The onsemi MC33262PG is a critical-conduction-mode power factor correction controller designed for boost-preconverter front ends in electronic ballasts and off-line power converters. The device operates from a 12 V to 28 V supply range, draws 6.5 mA of supply current, provides overvoltage protection, and uses a 50 kHz nominal switching frequency. It is supplied in an 8-pin plastic dual in-line package. The verified distributor listing identifies it as a PFC IC with Critical Conduction Mode operation. A PFC controller is a power-management IC that shapes the input current drawn from an AC source so that current and voltage are more nearly in phase. The MC33262 family places this function in a boost-converter control block placed ahead of a downstream rectifier and regulator. Improving power factor reduces reactive current and can reduce input-current stress, while critical-conduction mode supports controlled operation around the inductor-current transition. The controller is therefore positioned within the hierarchy AC input conversion, power factor correction, boost preconverter, power management IC, and semiconductor. Key verified attributes include an internal startup timer for standalone operation, a one-quadrant multiplier for near-unity power factor, and a zero-current detector for critical-conduction operation. The MC33262PG family is intended for electronic-ballast and off-line power-converter applications. Its 12 V to 28 V operating supply range is suited to rectified auxiliary buses commonly found in such equipment, while the 50 kHz nominal operating point places it in a useful control range for compact boost stages. The controller architecture supports independent sensing of the input and output voltage conditions through its externally connected pins. Designers must still provide the boost-inductor, switching transistor, rectifier, sensing network, timing components, and output-discharge provisions appropriate to the target converter. The zero-current detector and critical-conduction control reduce the risk of uncontrolled switch conduction, but component tolerances, propagation delays, and magnetic design remain important to stable power-factor correction. Typical applications include electronic ballasts, off-line AC-DC converters, switched-mode power supplies with active PFC, and industrial power systems that need reduced input-current distortion. The 8-PDIP package is through-hole and is mechanically convenient for leaded assemblies, repair products, and prototypes. It is not the same as an SOIC-8 package, so PCB or lead-frame substitution must be checked before reuse. For a new design, select the MOSFET, inductor, current-sense resistor, and optical or display feedback components against the required output power and voltage. Confirm the controller's 12 V minimum operating supply, 28 V maximum stated range, and the designer's surge requirements under worst-case mains conditions. Because the verified excerpt does not provide complete maximum ratings, timing values, protection thresholds, or thermal limits, consult the manufacturer datasheet before release to production. This page combines verified distributor identification, official family information, application context, packaging guidance, and a conservative replacement framework. It distinguishes confirmed MC33262PG attributes from parameters that still require full datasheet review, helping engineers identify the correct power factor controller without conflating it with unrelated MC33269 regulator data.
MC33287DWR2 - Dual Low-Side Switch w/ Contact Monitor | NXP
The NXP MC33287DWR2 is a contact-monitoring and dual low-side protected driver IC in a 20-pin SOIC (DW) wide-body package with an on-state resistance of 1.4 Ohm. It combines eight switch-contact sense inputs (switch-to-battery or switch-to-ground) with two internal low-side switches capable of driving inductive or capacitive loads. Supply voltage operates from 7 V to 18 V, and the part is qualified for surface-mount automotive and industrial assemblies. A Power Management IC (PMIC) of the contact-monitor/driver class, the MC33287 sits hierarchically between a microcontroller and physical switch/load interfaces. As a low-side switch it pulls load negative terminals toward ground; as a contact monitor it digitizes up to eight mechanical or electronic switch contacts with debounce and current limiting, replacing discrete resistors, diodes and comparators that previously consumed 100 mm² of PCB area. The device targets body-electronics ECUs, junction boxes, and industrial control panels where multiple wet/dry contacts must be sensed in a compact footprint. Key features include an on-state resistance of 1.4 Ohm per low-side driver, integrated flyback/clamping protection for inductive loads, programmable contact wetting current, switch-to-battery and switch-to-ground sensing in one IC, and built-in fault reporting through a status output. The 20-SOIC wide-body (7.5 mm) package provides adequate pin pitch for high-current PCB traces and standard hand-soldering rework. Architecturally the MC33287 combines an analog sense front-end, an 8-channel multiplexer, a microcontroller-compatible logic interface, and two protected DMOS low-side output stages. Each low-side driver integrates over-current, over-voltage, and thermal shutdown; the sense channels use a bandgap-referenced comparator for stable operation across -40C to +125C. Typical applications include automotive body controllers, junction boxes, HVAC mode-monitor panels, and industrial switch-input PLCs. The wide input range and integrated protection make it a single-chip replacement for dozens of discrete components. A design trade-off exists: the on-resistance of 1.4 Ohm causes ~0.7 W dissipation at 500 mA per channel, so thermal relief on the SOIC pad is required for continuous high-current operation.
