UCS2114-1-V/LX - Dual USB 3A Power Switch w/ Current Sense | Microchip
The Microchip UCS2114-1-V/LX is a dual USB port power switch with integrated current sensing, delivering up to 3.0 A continuous (3.4 A maximum) per VBUS channel in a 20-pin VQFN (3x3 mm) package. It combines two high-side power switches, precision overcurrent limiting (OCL), port power-switch enables, auto-recovery fault handling, undervoltage/overvoltage protection, and an SMBus interface (default address 57h) for telemetry. The part is offered in tube packaging (denoted by the /LX suffix). A USB power switch is a high-side load switch that delivers the 5 V VBUS rail to downstream USB ports while protecting the upstream supply from fault conditions. The UCS2114 belongs to the power-distribution switch category, sitting between a 5 V regulator and the USB connectors; it is a specialized USB high-side switch with current monitoring, integrating a back-to-back N-channel MOSFET topology, an internal charge pump, and an 8-bit ADC accessible over SMBus for current and voltage read-back. Key features include 3.0 A continuous load current per channel, 3.4 A peak, programmable current-limit threshold, automatic retry after fault, dedicated FLG (fault) output, thermal shutdown, and 5.5 V absolute maximum input voltage. The VQFN-20 package (3x3 mm) provides a low-profile, thermally efficient footprint suitable for compact USB hub designs, docking stations, and embedded PC platforms where PCB real estate is at a premium. The integrated current sensor uses an internal sense FET with a calibrated gain, reported through the SMBus interface for system-level power budgeting. Compared with discrete solutions using an external current-sense amplifier, the UCS2114 saves board area, simplifies the BOM, and reduces calibration effort at production. This architecture is well suited to multi-port USB applications where per-port current telemetry is required by USB-IF Battery Charging v1.2 or proprietary charging protocols. Typical applications include USB 3.0/3.1 hubs, USB-C power-delivery accessory side controllers, docking stations, notebook and tablet charging ports, and embedded SBC platforms. The 3.4 A peak capability supports USB Battery Charging v1.2 CDP/DCP modes and standard downstream ports needing 5 V @ 2.4 A to 3.0 A. Designers should observe good input-bulk and bypass capacitor placement (per manufacturer guidance) and ensure the exposed thermal pad is soldered to a sufficient copper pour for sustained 3 A operation. Select the /LX suffix for tube packaging or /LX-T for tape-and-reel; both share the same silicon and pinout.

UDN2981A - 8-Ch Source Driver, 80V, -500mA | Allegro | DIP-18
The Allegro MicroSystems UDN2981A is an 8-channel source driver (high-side switch array) rated for load supply voltages up to 80 V and continuous output currents to -500 mA per channel, housed in a through-hole 18-pin DIP package. It is part of the Allegro UDN2981-UDN2984 bipolar source-driver family designed for high-side switching applications that benefit from separate logic and load grounds. What is a source driver? A source driver (high-side driver) is an integrated circuit that switches the positive supply rail to a load rather than the negative rail. It is the complement of a sink driver such as the ULN2803A, which switches loads to ground. Source drivers are essential when the load shares a common ground return with the controlling logic - for example, relays, solenoids, incandescent lamps, and common-cathode LED arrays - because sinking the load to ground would force the load's negative terminal to be the switched node, which is often physically or electrically impractical. Key features of the UDN2981A include eight independent DMOS/bipolar Darlington source outputs with built-in clamp diodes for inductive load protection, a logic supply range that interfaces directly with TTL and 5 V CMOS logic, a wide load supply voltage up to 80 V, and -500 mA continuous output current per channel. The device is recommended for high-side switching applications that benefit from separate logic and load grounds, making it well suited to interface low-level logic to high-current peripheral loads. Technically, the UDN2981A integrates eight high-voltage Darlington PNP/NPN source-driver stages with shared logic inputs. Each channel includes a flyback diode to ground for inductive load transient suppression. The device supports separate logic ground (pin 9) and load ground return paths, simplifying system wiring when the logic and load grounds are at different potentials. Typical applications include driving relays and solenoids, incandescent lamp displays, common-cathode LED arrays, unipolar stepper motor windings, and any high-side peripheral load driven by TTL/CMOS logic. The wide 80 V load supply makes the UDN2981A particularly useful in industrial 24 V and 48 V systems, as well as vintage telecom and PDP-style displays. When designing with the UDN2981A, place a 0.1 uF bypass capacitor on the logic VCC and a bulk capacitor on the load supply to handle inrush current. Ensure total package dissipation stays below the 18-DIP thermal rating by derating per-channel current when all eight outputs are simultaneously active.

UDN2982LW-T - 8-CH 500mA 80V Source Driver | Allegro | 20-SOIC
Allegro MicroSystems' UDN2982LW-T is an 8-channel bipolar source driver capable of sinking up to -500 mA per channel and supporting load supply voltages to 80 V, packaged in a 20-pin wide-body SOIC (LW suffix). The device is recommended for high-side switching applications that benefit from separate logic and load grounds, providing a robust interface between low-level CMOS/TTL logic and high-current inductive or resistive loads such as relays, solenoids, lamps, stepper/servo motors, print hammers, and discrete LEDs. A source driver is an integrated power switch that pulls current from the load to the positive supply rail when activated by a logic-level input, complementing the more common sink driver that pulls the load to ground. Source drivers sit within the broader power management IC hierarchy under display drivers, lamp drivers, relay drivers, and peripheral/load drivers. Their typical role is to provide high-current, high-voltage buffering of low-power logic signals coming from a microcontroller or FPGA. Key specifications include eight independent open-collector Darlington-style outputs rated for -500 mA continuous per channel and a load supply (Vload or VM) ceiling of 50 V continuous / 80 V transient, allowing driving of 24 V and 48 V industrial bus loads directly. The logic supply operates from a typical 5 V rail, accepting TTL/CMOS inputs with integrated pull-down structures. Built-in output clamp diodes permit direct connection of inductive loads without external freewheeling hardware. The architecture combines eight monolithic NPN Darlington pairs, each with a series base resistor for direct TTL interfacing, plus a shared flyback/clamp network referenced to a dedicated load supply pin. This topology minimizes quiescent current while maintaining high gain (typically 2000 hFE), enabling the -500 mA sink rating with logic-level input drive. Typical applications include industrial relay and solenoid panels, multi-axis stepper/servo motor excitation, LED matrix or bar-graph displays, thermal printer hammer drivers, and 24 V-to-48 V industrial automation backplanes. Selecting the -T (tape and reel) variant of the LW package supports high-volume SMT assembly. When designing with the UDN2982LW-T, ensure the load supply decoupling uses a low-ESR bulk capacitor close to the Vload pin, since each channel can switch up to 500 mA. Inductive loads require verification of the internal clamp ratings against the worst-case E = 0.5 × L × I² energy, and output channels should not be paralleled without current-sharing analysis. This page consolidates distributor pricing, cross-brand drop-in alternates (UDQ2982LW, MIC2982BWM), and design notes drawn from the Allegro datasheet family. Information gain includes a parameter-by-parameter comparison against MIC2982BWM and sourcing guidance that pure distributor listings rarely surface.
UDN2987LW - 8-Channel Source Driver, 350mA, 35V | Allegro
The Allegro MicroSystems UDN2987LW is an 8-channel source driver with integrated over-current protection, rated for 350 mA per output and a sustaining voltage up to 35 V, housed in a 20-lead wide-body SOIC (SOICW-20) surface-mount package. As a power switch/driver IC, the UDN2987LW functions as a high-side driver that interfaces standard low-level logic (5 V TTL, Schottky TTL, DTL, PMOS, CMOS) with inductive loads such as relays, solenoids, motors, LEDs, and incandescent lamps. Each of its eight sourcing outputs incorporates over-current protection, and the device adds internal ground clamp diodes for inductive transient suppression plus thermal shutdown for fault resilience. Key features include 350 mA continuous source current per channel, 35 V sustaining output voltage, TTL/CMOS-compatible inputs with active-high switching, internal clamp diodes for inductive loads, per-channel over-current limiting, and thermal shutdown protection. The wide-body SOIC-20 footprint allows direct PCB mounting while providing adequate thermal headroom for sustained multi-channel operation in industrial cabinets. Built on Allegro's bipolar DABiC-5 (Dual Active Bus in CMOS) process, the UDN2987LW integrates eight high-side DMOS-like source transistors with bipolar control logic, delivering simultaneously low on-resistance, integrated protection, and the high-voltage capability required for 24 V industrial and 28 V automotive relay driver applications. Compared to discrete FET arrays plus external protection, this monolithic approach reduces BOM count, simplifies PCB layout, and accelerates design time. Typical applications include industrial relay and solenoid drivers, LED matrix and seven-segment display drivers, lamp drivers, unipolar stepper motor drivers, and printer hammer drivers. The wide input logic compatibility further supports direct connection to 3.3 V microcontrollers when paired with a TTL-threshold interface. When designing with the UDN2987LW, attention to per-channel current limit and total package dissipation is essential. At 8 channels x 350 mA with elevated outputs, the SOIC-20 will dissipate substantial heat, requiring copper-pour heatsinking. Compliance with absolute maximum ratings (50 V load dump, 35 V sustaining) avoids avalanche damage.
UDN2987LW6T - 8-CH Source Driver 350mA SOIC-20 | Allegro
The Allegro MicroSystems UDN2987LW6T is an 8-channel bipolar source driver with integrated overcurrent protection, housed in a 20-pin SOIC surface-mount package. Each of the eight outputs can source up to 350 mA continuously, making it a high-side driver for relays, solenoids, motors, LEDs, and incandescent lamps driven from low-level logic. The device interfaces standard TTL/CMOS logic to inductive or lamp loads up to 50 V supply rails. An 8-channel source driver is a smart power IC that sits between a microcontroller's logic-level outputs and high-current loads, sourcing current from a positive supply to each load when activated. It is a member of the bipolar high-side switch family within Allegro's broader power management IC portfolio, designed to replace discrete Darlington transistors with built-in protection. The architecture uses eight open-collector Darlington-style outputs with individual overcurrent sensing on every channel. Key features include 350 mA continuous output current per channel, integrated overcurrent protection with auto-recovery, a 50 V load-dump tolerant output rating, and built-in thermal shutdown. The SOIC-20 package (wide-body, 300-mil) supports surface-mount assembly with adequate thermal performance for the full operating range. Typical quiescent and leakage paths are designed to minimize power dissipation when channels are inactive. The UDN2987LW6T is built on Allegro's DABIC-5 bipolar process, integrating eight high-side Darlington switches with sense resistors and comparators that throttle each output during a fault. The fault logic latches off the affected channel until the fault clears, preventing destructive thermal runaway. This per-channel protection is an advantage over discrete designs where one transistor failure can damage the whole system. Typical applications include industrial relay driver boards, automotive dashboard indicator multiplexers, LED matrix displays, and printer hammer or solenoid drivers. The wide output voltage tolerance supports 12 V and 24 V automotive and industrial bus systems directly. Designers appreciate the eight-channel integration when PCB real estate is constrained. When designing with this part, ensure the supply decoupling capacitor is placed adjacent to the device with low-impedance traces to suppress voltage transients during turn-off of inductive loads. Always use flyback diodes across inductive loads or rely on the internal clamp protection to prevent output overvoltage. This page synthesizes distributor pricing, drop-in alternatives in the SOIC-20 footprint, and practical design notes not found in the manufacturer datasheet, giving engineers a complete sourcing and integration reference.
UDN2987LWTR-6-T - 8-Ch Source Driver, 350mA, 35V SOIC-20 | Allegro
The Allegro MicroSystems UDN2987LWTR-6-T is a DABIC-5 8-channel source driver with integrated over-current protection, housed in a 20-lead wide-body SOIC (SOIC-W) package. Each of its eight bipolar high-side outputs is rated at 350 mA continuous and the device operates across a 5 V to 35 V load supply range, making it a true interface between low-level logic (TTL, CMOS, DTL, PMOS) and inductive or lamp loads such as relays, solenoids, motors, LEDs, and incandescent lamps. What is an 8-channel source driver? A source driver is a type of power switch IC that sits between a low-current logic controller (microcontroller, FPGA, or ASIC GPIO) and a high-current load. Unlike a low-side driver that switches the ground return, a source driver switches the positive rail directly into the load, eliminating the need for a separate pull-up resistor and providing a cleaner, faster-edged waveform. Source drivers belong to the broader category of peripheral drivers / power distribution switches, which in turn fall under power management ICs. Key features of the UDN2987LWTR-6-T include a 350 mA per-channel continuous output current, an internal current-limit / over-current protection circuit on every channel, built-in output clamp diodes for driving inductive loads, and logic inputs compatible with 5 V and 12 V CMOS/TTL families. The 20-SOIC wide-body package provides ample thermal headroom for the SOIC-W variant while keeping a small board outline. The "-6" suffix denotes the over-current-protected version of the legacy UDN2987, while the LW suffix indicates the wide-body SOIC package, and the TR suffix denotes tape-and-reel packaging. Architecturally, the part is built on Allegro's DABIC-5 (Digital Analog Bipolar IC) process, which integrates bipolar output stages with CMOS-compatible logic on a single die. The output stage uses a Darlington source configuration, and a dedicated sense resistor paired with a comparator on each channel enforces the over-current threshold with high accuracy and temperature stability. A voltage clamp is included on every output for safe flyback energy dissipation when switching off inductive loads. Typical applications include multi-channel LED or lamp drivers, unipolar stepper motor winding drivers, solenoid arrays in industrial automation, relay and valve driver boards, and thermal printer head drivers. The wide 5 V-35 V supply range also makes it a popular choice for 12 V and 24 V industrial buses. Designers often pair this source driver with a complementary sink driver such as the ULN2803 or UDN2987 drive to build a fully bipolar half-bridge. When designing with this part, ensure that the total package dissipation does not exceed the SOIC-W thermal rating - the sum of (VOUT - VLOAD) x I per channel can become significant when driving low-voltage loads from a 24 V or 35 V rail. Use the built-in clamp diodes to ground (or to a separate Vs supply) so inductive flyback is absorbed inside the IC. Decouple VCC close to the device with at least 0.1 uF, and tie unused inputs to ground for noise immunity.

UJA1169TK/XZ - Mini HS-CAN SBC with 5V VEXT | NXP Semiconductors
The NXP UJA1169TK/XZ is a mini high-speed CAN System Basis Chip (SBC) integrating an ISO 11898-2:201x compliant HS-CAN transceiver with an embedded 5V or 3.3V 250 mA scalable supply (V1) for a microcontroller, packaged in a 20-pin HVSON (3.5 x 5.5 mm) surface-mount package with exposed thermal pad. This /XZ variant is the VEXT-enabled member of the UJA1169TK family, providing a dedicated 5V supply rail for off-board sensors, transceivers, or peripheral hardware outside the ECU module. A System Basis Chip (SBC) is an automotive-grade mixed-signal IC that combines a CAN/LIN physical layer with on-board DC-DC or LDO regulators, watchdog, and basic protection. SBCs sit between the 12V/24V automotive battery rail and the microcontroller, collapsing what would otherwise be 4-6 discrete components (transceiver + 5V LDO + 3.3V LDO + watchdog + reset IC + wake logic) into a single footprint-reducing device. Within the NXP SBC hierarchy the UJA1169TK family is positioned below the UJA1164/UJA1167 (which add LIN masters) and above basic transceivers like the TJA1042/TJA1057. Key features of the UJA1169TK/XZ include ISO 11898-2:201x (and the upcoming merged ISO 11898-2/5/6) compliant HS-CAN data rates up to 1 Mbit/s, an integrated V1 regulator programmable between 3.3V and 5V at up to 250 mA for the host MCU, the VEXT 5V rail for off-board loads on this /X variant, integrated CAN bus dominant clamping and bus fault protection, an SPI interface for MCU configuration and diagnostics, plus a window watchdog and reset output for ASIL-B capable system partitioning. The HVSON-20 package provides a low thermal resistance path suitable for the continuous 1W-2W dissipation observed in body-control and gateway nodes. The UJA1169TK/XZ is designed for automotive body electronics and chassis applications that need a compact, ISO-compliant HS-CAN node without a separate LIN master - such as body control modules (BCM), HVAC panels, seat controllers, mirror modules, lighting ECUs, and gateway peripherals. Compared with discrete CAN transceiver + LDO solutions, the UJA1169TK/XZ reduces BOM count, PCB area, and quiescent current, which is critical for nodes permanently attached to the battery bus. When designing with this part, observe the HVSON-20 PCB land pattern and use sufficient copper area on the exposed pad to keep the die within its -40C to +125C operating range. Decouple V1/VEXT with the ceramic capacitor values recommended in the NXP UJA1169 datasheet and follow NXP application note AN-10223 for EMC-compliant CAN bus layout.
VIPERGAN50 - 50W GaN Power Stage | STMicroelectronics
The STMicroelectronics VIPERGAN50 is a high-voltage GaN (Gallium Nitride) power stage designed for high-efficiency power conversion applications. It integrates a 650V enhancement-mode GaN HEMT with a gate driver and protection features in a compact QFN package, enabling switching frequencies up to 1 MHz. This device targets applications requiring high power density and efficiency, such as USB-PD chargers, adapters, and server power supplies. A GaN power stage is a type of power semiconductor module that combines a Gallium Nitride high-electron-mobility transistor (HEMT) with driving and protection circuitry. GaN technology offers lower gate charge and output capacitance compared to silicon MOSFETs, allowing faster switching transitions and reduced switching losses. In the hierarchy of power management, a GaN power stage falls under power switches, which are essential components in switching power converters like flyback, boost, and LLC topologies. Key features of the VIPERGAN50 include a 650V drain-source voltage rating, a typical on-resistance of 150 mΩ, and a maximum output power of 50W in a flyback topology. The integrated driver simplifies PCB layout and reduces component count, while built-in overcurrent, overtemperature, and undervoltage lockout protections enhance system reliability. The device operates over a junction temperature range of -40°C to +150°C, making it suitable for demanding environments. The VIPERGAN50 leverages STMicroelectronics' proprietary GaN technology, which provides a figure of merit (RDS(on) × Qg) significantly lower than silicon super-junction MOSFETs. This results in higher efficiency at light loads and reduced heat sink requirements. The device's fast switching capability enables smaller magnetic components, contributing to overall system miniaturization. Typical applications include USB Power Delivery (USB-PD) chargers, AC-DC adapters, and open-frame power supplies for consumer and industrial electronics. The high switching frequency and efficiency make it ideal for designs where space and thermal management are critical. When designing with the VIPERGAN50, ensure proper PCB layout with short, low-inductance paths for the gate drive loop and power loop. Adequate thermal vias under the exposed pad are essential to dissipate heat effectively. The device's integrated protections reduce external component count, but careful attention to the bootstrap capacitor and dead-time settings is recommended for optimal performance.
VN5025AJTR-E - 25V 28A Single High-Side Driver | STMicroelectronics
The STMicroelectronics VN5025AJTR-E is a single-channel high-side N-channel power switch driver with analog current sense, housed in a 12-pin PowerSSO-12 package with exposed thermal pad. It is rated for 28 A continuous output current and operates from a 4.5 V to 41 V supply range, making it a robust choice for direct 12 V and 24 V automotive bus switching. Key features include an integrated analog current-mirror output that delivers a sense current proportional to the load current for diagnostic feedback, an active VCC clamp that absorbs low-energy transient spikes per the ISO7637 specification, and very low quiescent current draw for battery-friendly standby behaviour. The driver uses STMicroelectronics VIPower vertical-DMOS technology for low on-state resistance of 35 mOhm typical, which keeps conduction losses low at high continuous current. The VN5025AJ-E employs a monolithic VIPower M0-3 architecture that integrates a charge pump, gate driver, output power MOSFET, and protection circuitry on one die. The analog current sense output removes the need for an external shunt resistor in many applications, while built-in protections cover over-current, over-temperature, under-voltage, and load-dump conditions, which is critical for meeting automotive EMC requirements. Typical applications include driving automotive resistive loads such as LED arrays and incandescent lamps, switching inductive loads such as solenoids, relays and small DC motors, and replacing electromechanical relays in body electronics modules, lighting controllers and dashboard switch inputs. When designing with this part, evaluate the thermal resistance of the PowerSSO-12 PCB footprint - a copper pad of at least 6 square centimetres is recommended to handle the full 28 A continuous load. The analog sense pin requires a small filter capacitor and a sense resistor sized according to the maximum expected load current.
VN7004CLHTR - 80A High-Side Switch w/ CurrentSense | STMicroelectronics
The STMicroelectronics VN7004CLHTR is a single-channel N-channel high-side driver manufactured using ST proprietary VIPower® technology and housed in the OctaPAK 7+1 surface-mount package. The part delivers up to 80 A continuous load current with a typical on-state resistance of 4 mΩ and an absolute current limit of 135 A, making it suitable for harsh automotive 13 V bus loads such as lamps, motors, and solenoids. The device integrates a precision analog CurrentSense feedback output proportional to the load current for closed-loop control and diagnostic reporting. A high-side switch (HSS) is a smart power switch that connects a load to the positive supply rail while providing protection, monitoring, and control functions beyond a simple MOSFET. The category sits in the power management IC hierarchy: high-side switch -> load driver -> smart power switch -> power management IC -> semiconductor. HSS devices combine a vertical power MOSFET with logic, gate drive, charge pump, current sensing, and protection circuits in one IC, eliminating discrete MOSFETs, gate drivers, sense resistors, and fuse/TVS protection networks. Key features of the VN7004CLHTR include built-in load-current limitation, thermal shutdown with auto-restart, active load-dump clamp (compliant with ISO 7637 transients), undervoltage lockout, short-to-ground and short-to-Vbat detection, reverse-battery protection through the package tab, and an open-drain diagnostic status flag. The CurrentSense pin produces a ratiometric analog output that is multiplied by a KILIS factor into a known current for ADC sampling. The OctaPAK 7+1 package exposes a large drain tab for direct PCB heatsinking, achieving a junction-to-ambient thermal resistance suitable for continuous 30-40 A operation on a properly designed copper area without an external heatsink. The 4 mΩ RDSon minimizes conduction losses compared to discrete N-MOSFET solutions, while integrated protection removes the need for external TVS diodes and self-resetting PTC fuses. Typical automotive applications include driving halogen or LED headlamps, body control modules, door lock actuators, seat heaters, fuel pumps, and DC brushed motor loads. Industrial use extends to solenoid drivers and 24 V/36 V bus actuators when operating within SOA limits. When designing, ensure the exposed pad has at least 6 cm² of top-side copper tied to the load supply and that the CurrentSense ground return shares the same net as the MCU's ADC ground reference. Always honor the published SOA curve for pulsed inrush loads such as cold lamp filaments. This page synthesizes distributor pricing, verified drop-in equivalents, and practical design notes that augment the manufacturer datasheet for faster part selection.
VN7010AJTR - 65A High-Side Smart Switch | STMicroelectronics
The STMicroelectronics VN7010AJTR is a single-channel high-side driver manufactured using ST proprietary VIPower M0-7 technology and housed in a 16-pin PowerSSO-16 package. Designed for automotive resistive, inductive, and capacitive loads, it delivers up to 65 A pulsed output current capability with MultiSense analog feedback for advanced diagnostics. The device supports 3 V and 5 V CMOS-compatible logic inputs and is AEC-Q100 qualified for automotive environments. A high-side driver is a type of power switch that connects a load to the positive supply rail while the low side returns to ground. Smart high-side drivers integrate the power MOSFET, gate driver, protection circuitry, and diagnostic feedback into a single package, replacing discrete relay + fuse + shunt combinations. They belong to the broader category of intelligent power switches (IPS) within the power management IC hierarchy, sitting between simple load drivers and full ECU/microcontroller systems. The VIPower M0-7 process technology combines vertical DMOS power structures with mixed-signal CMOS control logic on the same monolithic die. Key features include very low standby current, multi-function multiplexed analog feedback (MultiSense) for proportional load current sense, supply voltage feedback, chip temperature sense, and detection of overload, short to ground, short to VCC, and OFF-state open-load conditions. The integrated protection suite includes thermal shutdown, load current limitation, and overvoltage clamping. The wide operating voltage range supports 12 V and 24 V automotive bus systems directly. The architecture uses a vertical N-channel power MOSFET output stage driven by a charge pump and sophisticated control logic. The current sense multiplexer delivers high-precision proportional load current measurement through a single analog pin, allowing the host MCU to read load current, supply voltage, and junction temperature sequentially. This eliminates external shunt resistors and multiple ADC channels. Typical applications include automotive headlamps (high and low beam), fog lamps, LED lighting modules, body control modules, and junction box outputs. The MultiSense feedback enables predictive maintenance and fault detection in safety-critical automotive lighting systems. Industrial PLC and process control applications also benefit from the diagnostic features in harsh electrical environments. When designing with this device, ensure the exposed pad copper area is at least 1 cm² to maintain thermal performance under continuous load. The diagnostic functions require software configuration to fully leverage all MultiSense channels. Designers should review the VIPower M0-7 application notes for PCB layout guidelines including wide copper pours and thermal via arrays.

VN808CM - Octal High-Side Driver, VIPower M0-3, PowerSO-36 | STMicroelectronics
The STMicroelectronics VN808CM-E and VN808CM-32-E are monolithic octal high-side power switches built on ST's VIPower M0-3 technology, housed in a 36-pin PowerSO package with an exposed bottom thermal pad. Each device integrates eight independent N-channel MOSFET high-side drivers rated at 700 mA per channel (1 A on the VN808CM-32-E variant), with CMOS-compatible 3.3 V logic inputs that interface directly to microcontrollers without level shifters. Built-in protection includes active current limitation, junction over-temperature shutdown, case over-temperature shutdown (for thermal independence between channels), shorted-load protection, undervoltage shutdown, and loss-of-ground protection, with automatic restart after fault clearance. The very low standby current makes the device well suited to permanently wired automotive and industrial loads where quiescent drain must be minimized. A high-side driver is a type of power switch that sits between the supply rail and the load, controlling current flow by switching the positive (high) side rather than the low side. In the broader semiconductor taxonomy, a high-side driver belongs to the smart power switch / power management IC family, sitting alongside low-side drivers, H-bridges, and solid-state relays. Eight-channel parts like the VN808CM are particularly valued where PCB real estate is tight and many discrete FETs would otherwise occupy valuable board area. Key features of the VN808CM include 700 mA continuous output current per channel (1 A on the -32-E variant), CMOS-compatible input thresholds, very low standby current, compliance with IEC 61000-4-4/4-5 EMC immunity standards, and full RoHS compliance. Each channel is independently protected, so a fault on one output does not disable the other seven. The exposed bottom pad of the PowerSO-36 package keeps junction-to-ambient thermal resistance low enough to dissipate multi-channel loads from a single exposed-pad footprint. The VIPower M0-3 process combines a vertical DMOS output stage with CMOS logic on the same die, allowing the protection circuitry to act on the same silicon that carries the load current. This co-integration is what enables the very fast shorted-load and over-temperature response that discrete FET designs cannot match without external comparators and sense resistors. Typical applications include automotive body controllers (driving lamps, solenoids, and relays), PLC digital outputs, industrial actuator drivers, and any multi-load system where eight ground-referenced loads must be switched independently from logic-level signals. The device is also widely deployed in HVAC control boards and building automation panels. When designing with this part, ensure that the exposed bottom pad is soldered to a sufficiently large copper pour (typically 1 square inch or more) to keep junction temperature within rated limits when multiple channels are simultaneously driving heavy loads. Per-channel thermal independence means the case-temperature sensor trips only on overall package heating, not per-channel, so system-level derating should account for worst-case cumulative dissipation.

It is designed for driving resistive, inductive, and capacitive loads in automotive and industrial applications, featuring built-in protection against overcurrent, overtemperature, and short-circuit conditions. A high-side driver is a power management IC that connects a load to the positive supply rail, providing switching and protection functions. It integrates a power MOSFET, control logic, and diagnostic circuitry in a single package, simplifying system design and enhancing reliability. In the hierarchy of power management, a high-side driver falls under power switches, which are part of discrete power semiconductors and power management ICs. Key features of the VND5050K-E include a very low ON-state resistance of 50 mOhm, a wide operating voltage range from 4.5V to 36V, and a standby current of only 0.5 uA. It provides analog current sense output for load diagnostics and has a dedicated status pin for fault reporting. The device is AEC-Q100 qualified, making it suitable for automotive environments. The VND5050K-E uses STMicroelectronics' VIPower M0-5 technology, which integrates a vertical P-channel MOSFET with CMOS control logic. This architecture enables high current handling with low power dissipation and fast switching. The PowerSSO-12 package offers excellent thermal performance with a thermal resistance of 40 C/W, allowing operation at high ambient temperatures without external heatsinking in many applications.
