Description
VN751S is a single-channel automotive high-side switch (smart switch) used to drive a load from a vehicle power bus under MCU control. It combines a power MOSFET, control logic, and protection/diagnostic features in one package to simplify ECU hardware.
Key points:
- Control: a logic input enables/disables the switch; diagnostic/status feedback is available to the MCU.
- Protections: overcurrent/short to supply or ground, undervoltage, thermal shutdown, reverse polarity, and load-dump tolerance (varies by model).
- Applications: drives DC actuators, lamps, solenoids, etc., from 12–24 V automotive systems.
- Variants: different current ratings and protection options; check the exact VN751S datasheet for precise electrical specs (voltage range, current limit, timing, latch behavior).
In short: a compact, protected interface between the vehicle power line and a single load, controlled by a microcontroller.

Equivalent
VN751S is STMicroelectronics’ VIPower automotive high‑side switch. For exact substitutes, please share its specs (max supply voltage, continuous current, package, protections). As starting cross‑references, check TI TPS1Hx series and similar automotive high‑side switches from On Semiconductor, Renesas, and NXP. With your specs, I can give precise cross‑reference part numbers.
Pinout
VN751S isn’t unique to a single device—several manufacturers use that designation. Pin count and pin functions depend on the exact part (manufacturer and package). Please provide the manufacturer or a datasheet/link for VN751S you’re referring to. I can then give the exact pin count and each pin’s function.
Manufacturer
- Manufacturer: STMicroelectronics (ST).
- What kind of company: A global (multinational) semiconductor company that designs, develops, and manufactures integrated circuits and electronic components for automotive, industrial, consumer, and other markets.

Application
VN751S is a high‑side switch IC for DC loads (with current limit, fault/diagnostics). Typical application areas:
- Automotive body electronics: exterior/interior lighting, pumps, fans, wipers, door modules
- Industrial/automation: DC motors, actuators, solenoids, valve drivers
- General 12–24 V load switching in ECUs with protection/diagnostics
- LED driver and lighting control (constant‑current loads)
Provides overcurrent, overtemperature/undervoltage protection and diagnostic feedback for reliable load switching.
