Product details
Overview
VN750PS-E from STMicroelectronics is a high-side power switch IC designed for automotive-grade load driving with one side grounded. It delivers 6 A continuous output current, features 60 mΩ on-state resistance at 25°C, supports 36 V supply voltage, and integrates on/off-state open-load detection, short-circuit protection, and reverse-battery protection - used in body control modules for controlling lamps, solenoids, and relays.
For engineers reviewing the VN750PS-E datasheet, VN750PS-E pinout, VN750PS-E application, or VN750PS-E equivalent, key selection criteria include its AEC-Q100 compliance, integrated status feedback via dedicated STATUS pin, thermal shutdown with automatic restart, ISO 7637-2 transient immunity, and SO-8 package suitability for space-constrained automotive PCBs.
Technical Context
The VN750PS-E implements a monolithic VIPower™ M0-3 process high-side driver architecture with CMOS-compatible input logic and active clamp circuitry on the VCC pin to absorb low-energy transients per ISO 7637-2 Pulse 1, 2a, 3a/b, and 5a. Its internal current limiter dynamically adjusts threshold (6–15 A) based on junction temperature and supply voltage.
Protection logic includes dual-mode open-load detection: during ON-state, it monitors output current below 50–200 mA; during OFF-state, it senses output voltage above 1.5–3.5 V. Ground disconnection triggers immediate shutdown, and reverse-battery events are mitigated by an external GND network (resistor or diode-based).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Operating Range | 5.5 V to 36 V - supports full automotive battery range including cold-crank (5.5 V) and load-dump (36 V) |
| RDS(on) | 60 mΩ max at IOUT = 2 A, Tj = 25°C - enables low conduction loss and minimal self-heating under 6 A load |
| IOUT Continuous | 6 A - rated output current with thermal derating above 25°C ambient per SO-8 thermal data |
| Open-Load Detection | ON-state: 50–200 mA threshold; OFF-state: 1.5–3.5 V threshold - enables diagnostics without external components |
| Protection Features | Undervoltage (4 V), overvoltage (36 V), thermal shutdown (150–200°C), short-circuit, reverse-battery - autonomous fault response without MCU intervention |
| Status Pin Output | Open-drain, 0.5 V low-level voltage at 1.6 mA - provides real-time diagnostic feedback compatible with 3.3 V/5 V microcontrollers |
| ISO 7637-2 Immunity | Pulse 1/2a/3a-b/C pass; Pulse 4/E fail - validated against automotive electrical transients except sustained negative supply dips |
Pinout & Package
The VN750PS-E 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; device orientation follows JEDEC MS-012AC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1, 2) | Power supply input | Dual-pin connection improves current handling and reduces trace inductance; clamped internally to ~41 V for transient suppression |
| GND (Pin 3) | Power ground reference | Primary return path for load current and internal bias; requires low-impedance PCB copper pour |
| INPUT (Pin 4) | CMOS-compatible control input | Accepts 1.25 V low / 3.25 V high logic; 0.5 V hysteresis prevents noise-induced switching |
| OUTPUT (Pin 5, 6) | High-side switched output | Drives loads connected between OUTPUT and ground; pins paralleled for lower RDS(on) and higher current capability |
| N.C. (Pin 7) | No-connect terminal | Internally unconnected; must remain floating or tied to GND per ST recommendation for EMI stability |
| STATUS (Pin 8) | Diagnostic open-drain output | Asserts low during faults (overtemp, overload, open-load); pulled up externally to monitor health in real time |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 (−40°C to +125°C ambient), certified per ST's automotive quality program |
| Integrated diagnostics | Single-pin STATUS output reports open-load (ON/OFF), overcurrent, overtemperature, undervoltage, and overvoltage - eliminates need for external sense resistors or comparators |
| Robust transient immunity | VCC pin withstands ISO 7637-2 Pulse 1 (−100 V), Pulse 2a (+100 V), Pulse 3a/b (±150 V), and Pulse 5a (+86.5 V) without latch-up or damage |
| Low-power standby | 20 µA max supply current at 13 V, 25°C - suitable for always-on vehicle systems requiring ultra-low quiescent consumption |
| Reverse-battery resilience | Supports external GND protection network (RGND ≤ 600 mV/IS(on)max or DGND + 1 kΩ) to prevent damage during −12 V battery reversal |
Applications
| Lamp Control Module | Engine Management Solenoid Drive |
|---|---|
Use Scenario: Driving 12 V halogen or LED headlamps in modern BCMs with PWM dimming and diagnostics.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STVN7008AJTR | Lower RDS(on) (30 mΩ), 8 A rating, same SO-8 package, but no off-state open-load detection | Preferred for higher-current resistive loads where diagnostic depth is secondary to conduction efficiency | Select when peak load exceeds 6 A and STATUS diagnostics are handled externally |
| Infineon BTS7008-1EPA | Higher quiescent current (60 µA), identical protection set, but requires external pull-up on INH pin for enable control | Better suited for systems using dedicated enable signals rather than direct GPIO drive | Choose when board layout allows extra routing for enable control and STATUS is monitored via separate ADC channel |
Compared with VN750PS-E, STVN7008AJTR offers higher current capacity but sacrifices off-state diagnostics, while BTS7008-1EPA trades lower standby power for added control complexity - VN750PS-E uniquely balances integrated diagnostics, AEC-Q100 compliance, and SO-8 thermal performance in a single GPIO-driven device.

FAQ
What is the maximum safe operating temperature for VN750PS-E?
The VN750PS-E features internal thermal shutdown triggered at 150–200°C junction temperature, with reset occurring at 135°C. Under typical SO-8 mounting (2 cm² copper), it sustains 6 A continuous output up to 85°C ambient; derating is required above that per Figure 29's Rthj-amb = 82°C/W curve.
Does VN750PS-E require external components for basic operation?
Yes - a pull-up resistor (typically 10 kΩ) on the STATUS pin is mandatory for open-drain output functionality, and external RC filtering on INPUT may be needed in noisy environments. For reverse-battery protection, ST recommends either a series resistor (≤600 mV/IS(on)max) or Schottky diode in the GND line per Section 2.5.
How does the open-load detection work in OFF-state?
In OFF-state, the VN750PS-E applies a small test current through the output and measures resulting voltage: if VOUT > 1.5–3.5 V (depending on temperature), it indicates an open circuit. This occurs within 1000 µs of turn-off and asserts STATUS low, enabling immediate firmware response without polling.
Can VN750PS-E drive inductive loads like fuel injectors?
Yes - it supports inductive loads up to 6 mH with VCC-clamped demagnetization (Vdemag = VCC−41 V to VCC−55 V). ST specifies maximum turn-off energy of 100 mJ at 13.5 V; external flyback diodes are not required, but PCB copper area must meet thermal guidelines in Section 3.1.
