STMicroelectronics VN750-E

Overview

VN750-E from STMicroelectronics is a monolithic high-side power switch fabricated in VIPower® M0-3 technology, designed to drive grounded loads in automotive and industrial systems. It features 60 mΩ R_DS(on), 6 A continuous output current, 36 V maximum supply voltage, on/off-state open-load detection, and integrated short-circuit, overtemperature, undervoltage, and overvoltage protection.

For engineers reviewing the VN750-E datasheet, VN750-E pinout, VN750-E application, or VN750-E equivalent, this device is selected for robust load control in 12 V/24 V battery-powered systems requiring diagnostic feedback, reverse-battery immunity, and ISO 7637-2 transient resilience.

Technical Context

The VN750-E implements a CMOS-compatible input interface with 0.5 V hysteresis and active status pin reporting (low-voltage logic output with 0.5 V max drop at 1.6 mA). Its internal current limiter activates at 6–15 A depending on V_CC, and thermal shutdown triggers at 150–200 °C with 7–15 °C hysteresis.

Protection architecture includes active V_CC clamping for low-energy transients (ISO 7637-2 pulses 1–3b), loss-of-ground detection via GND pin disconnection monitoring, and dual-mode open-load sensing: current-based during ON-state (50–200 mA threshold) and voltage-based during OFF-state (1.5–3.5 V threshold).

Key Specifications

Pinout & Package

The VN750-E is supplied in the PENTAWATT (in-line) package - a 5-pin, through-hole, thermally enhanced plastic package with exposed metal tab for heatsinking. Pin 1 is INPUT, Pin 2 is GND, Pin 3 is OUTPUT, Pin 4 is STATUS, Pin 5 is V_CC.

Equivalent & Alternatives

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

Compared with VN750PT-E, the VN750-E offers superior mechanical serviceability and legacy compatibility but higher thermal resistance; versus TPS27081A, it delivers complete automotive fault coverage at the expense of higher R_DS(on) and cost - making it the preferred choice for safety-critical, diagnostic-enabled systems.

Availability

VN750-E is available at Aetrix Electronics and suitable for body control modules, engine management systems, commercial vehicle telematics units, and industrial power distribution panels requiring stable component supply across extended product lifecycles.

Supply support for VN750-E includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

FAQ

What is the maximum inductive load energy the VN750-E can safely demagnetize?

The VN750-E supports up to 138 mJ of demagnetization energy when mounted on a standard FR-4 board with 0.5 cm² copper (PENTAWATT package, V_CC = 13.5 V, I_L = 9 A). This value is validated per ST's test conditions in Section 2.9 and assumes proper PCB thermal design - exceeding it risks voltage overshoot beyond the internal clamp limit.

Does the VN750-E require an external pull-up resistor on the STATUS pin?

Yes - the STATUS pin is an open-drain output and requires an external pull-up resistor (typically 4.7 kΩ to V_CC or microcontroller I/O rail) to generate a valid high-level logic signal. Without it, the pin remains floating during normal operation and cannot indicate fault-free status reliably.

How does the VN750-E detect loss of ground connection?

The device monitors current flow through its GND pin using an internal sense network. If GND is disconnected while the output is active, the resulting imbalance triggers immediate shutdown and asserts the STATUS pin low. This function operates independently of V_CC level and is specified to respond within milliseconds per ST's protection timing diagrams.

Can the VN750-E be used in 48 V mild-hybrid automotive systems?

No - the absolute maximum V_CC rating is 41 V DC, and overvoltage shutdown activates at 36 V. While brief transients up to 41 V are tolerated, sustained operation above 36 V will cause shutdown. For 48 V systems, ST recommends the VNQ7E100AJ or similar 80 V-rated high-side drivers from the VIPower M0-7 family.
