Product details

Overview

VN750S from STMicroelectronics is a high-side power switch IC designed for driving grounded loads in automotive and industrial control systems. It features 60 mΩ R_DS(on), 6 A continuous output current, 36 V supply voltage rating, CMOS-compatible input, and integrated open-load detection in both on- and off-states. It is commonly used in body electronics such as lamp and solenoid control where robust fault diagnostics and reverse-battery protection are required.

For engineers reviewing the VN750S datasheet, VN750S pinout, VN750S application, or VN750S equivalent, key selection criteria include its active current limiting (6–15 A), thermal shutdown with 150°C trip point, SO-8 package thermal resistance (R_thj-amb = 93°C/W on minimal copper), and dual-state open-load detection capability.

Technical Context

The VN750S implements VIPower® M0-3 technology to integrate power MOSFET, protection logic, and diagnostic circuitry in a single monolithic die. Its architecture includes an active VCC clamp for low-energy spike suppression, ground-loss detection that forces automatic shutdown upon GND disconnection, and bidirectional open-load sensing using internal current comparators and status pin feedback.

Electrical behavior is defined by three critical protection thresholds: undervoltage shutdown at 4 V (±0.5 V hysteresis), overvoltage shutdown at 36 V, and thermal shutdown at 150°C with 135°C reset. The device operates across -40°C to 150°C junction temperature and supports load dump transients per ISO 7637-2 Pulse 5a.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	60 mΩ max at 2 A, 25°C - ensures <150 mW conduction loss at rated load
I_OUT continuous	6 A - supports automotive lamps, valves, and small motors without external heatsink
V_CC range	5.5–36 V - compatible with 12 V and 24 V vehicle electrical systems
Open-load detection	On-state: 50–200 mA threshold; Off-state: 1.5–3.5 V threshold - enables diagnostics without external components
Thermal shutdown	150°C trip, 135°C reset - prevents latch-up during sustained overload or short-circuit
Standby current	10–25 µA at 13 V - minimizes battery drain in always-on vehicle modules
Reverse battery protection	Integrated GND network - eliminates need for external series diode in battery-reversal-prone environments

Pinout & Package

The VN750S is housed in a standard SO-8 surface-mount package with exposed pad for thermal enhancement. Pin 1 is marked by a notch or dot; pins are numbered counterclockwise from top-left when viewed from top.

Pin/Terminal	Circuit Role	Design Meaning
1 (INPUT)	Digital control input	CMOS-compatible; accepts 3.25 V high / 1.25 V low; 10 µA max input current
2 (GND)	Power ground reference	Ground-loss detection node; device shuts down if disconnected from system ground
3 (OUTPUT)	High-side switched output	Drives load between OUTPUT and system ground; supports inductive demagnetization clamping
4 (STATUS)	Fault and diagnostic output	Open-drain output indicating open-load, overtemperature, overvoltage, or undervoltage conditions
5–8 (VCC)	Power supply input	Multiple VCC pins share current and reduce trace inductance; internal clamp protects against 41 V spikes

Key Features

Feature	Design Value
On/Off-state open-load detection	Enables full-cycle diagnostics without external sense resistors or microcontroller polling overhead
Active current limitation	6–15 A foldback limit prevents destructive energy buildup during short circuits
Undervoltage & overvoltage shutdown	Prevents erratic switching during battery faults (e.g., alternator failure or jump-start surge)
Reverse battery protection	Eliminates need for external series diode, reducing BOM cost and forward voltage drop
Very low standby current	≤25 µA allows use in always-on vehicle modules without compromising battery life

Applications

Automotive Lighting Control

Industrial Solenoid Driver

Use Scenario: Controlling headlamp, fog lamp, or interior lighting circuits in 12 V vehicle platforms.

IC Role / Device Role / Timing Role: High-side switch providing load isolation, PWM dimming support, and real-time fault reporting via STATUS pin.

Use Value: Integrated open-load detection replaces external current-sense amplifiers; reverse-battery tolerance avoids fuse blowouts during service errors.

Use Scenario: Driving 24 V DC solenoids in factory automation valves and pneumatic actuators.

IC Role / Device Role / Timing Role: Robust power interface with fast turn-off (<30 µs) and inductive kick clamping up to VCC − 55 V.

Use Value: Eliminates need for external flyback diodes and reduces PCB area; thermal shutdown prevents coil burnout during jammed actuator conditions.

Body Control Module (BCM)

Truck & Bus Auxiliary Power

Use Scenario: Managing seat heater, mirror defogger, or window lift motor outputs in centralized BCM units.

IC Role / Device Role / Timing Role: Protected high-side driver with diagnostic feedback for ECU-level error logging and CAN message generation.

Use Value: STATUS pin provides direct hardware-level fault classification (open-load vs. short-to-VCC vs. overtemp), reducing software diagnostic complexity.

Use Scenario: Switching auxiliary 24 V loads (e.g., refrigeration units, air horns) in commercial vehicles with wide supply variation.

IC Role / Device Role / Timing Role: Wide-input (5.5–36 V) high-side driver with load-dump immunity per ISO 7637-2 Pulse 5a.

Use Value: Internal VCC clamp and 41 V absolute max rating withstand generator load-dump events without external TVS diodes.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-side driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STVN751S	Higher R_DS(on) (100 mΩ), same SO-8 package, identical pinout	Lower current capability (4 A) and reduced thermal margin; suitable only for lighter loads	Select when lower cost is prioritized and peak load current remains ≤4 A
INFINEON BTS716G	60 mΩ R_DS(on), 6 A, but requires external pull-down on IN pin; no off-state open-load detection	Lacks integrated off-state diagnostics; STATUS functionality limited to overcurrent/overtemp only	Choose only if board space permits external resistor network and diagnostics are handled solely in firmware

Compared with VN750S, STVN751S trades current capability for cost, while BTS716G sacrifices diagnostic completeness for broader supplier availability-neither offers the same combination of SO-8 footprint, dual-state open-load detection, and reverse-battery protection.

FAQ

What is the maximum inductive load energy the VN750S can safely demagnetize?

The VN750S supports up to 100 mJ of demagnetization energy in SO-8 package at V_CC = 13.5 V, T_jstart = 150°C, and I_L = 9 A. This value is validated per test condition L = 1.8 mH, R_L = 0 Ω, and defines the upper bound for safe inductive turn-off without external snubbers.

Does the VN750S require an external pull-up resistor on the STATUS pin?

Yes - the STATUS pin is open-drain and must be pulled up externally (typically 4.7 kΩ to V_CC) to generate valid logic-high fault signals. Without this pull-up, the pin cannot indicate normal operation or distinguish between open-circuit and active-low fault states.

Can the VN750S drive capacitive loads directly?

No - the VN750S is not characterized for direct capacitive load switching. Large capacitive loads may cause excessive inrush current exceeding the 15 A current limit, triggering repeated thermal shutdown. External current-limiting resistors or soft-start circuitry are required for such applications.

How does the VN750S detect loss of ground connection?

The device monitors internal GND path integrity via dedicated sensing circuitry. If the GND pin disconnects from system ground, the IC immediately disables the output and asserts the STATUS pin low within 20 ms, preventing uncontrolled floating output voltage and ensuring fail-safe behavior.
