Diagnostic feedback (open-load, thermal, short) is multiplexed through a single STATUS pin for microcontroller monitoring. Typical applications include automotive body control units driving door-lock motors, window lifters, mirror adjusters, seat motors, lighting relays, and HVAC flap actuators. The wide supply range tolerates cranking transients on 12 V automotive rails while the 9 A continuous rating supports high-inrush loads such as DC motors at startup. The IC also suits industrial relay and solenoid driver boards and small appliance motor control where multiple half-bridges per package reduce BOM count and PCB area. When designing with the VN771KP-E, ensure adequate copper pour on all source pins to share the high ground-return current and to keep RDSon losses within thermal limits.

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.
