Product details
Overview
VN7050AS-E from STMicroelectronics is an evaluation board pre-assembled with the VN7050AS single-channel smart high-side driver in SO-8 package, designed for 12 V automotive grounded loads. It supports 4–28 V operating voltage, delivers 30 A current limiting, features 50 mΩ on-state resistance, and provides proportional analog current sense (MultiSense) with diagnostic enable/disable control.
For engineers reviewing the VN7050AS-E datasheet, VN7050AS-E pinout, VN7050AS-E application, or VN7050AS-E equivalent, this board enables rapid prototyping of automotive load driving with integrated protection, thermal shutdown, open-load detection, short-to-VCC/ground diagnostics, and CMOS-compatible 3 V/5 V interface control.
Technical Context
The EV-VN7050AS board implements ST's VIPower® M0-7 technology via the VN7050AS IC, integrating high-side switching, real-time current sensing, and multi-fault diagnostics into a single SO-8 device. It operates across 4–28 V supply range and withstands up to 40 V transient voltage.
Diagnostic functions include OFF-state open-load detection (via optional IN_PullUP), active short-to-ground indication, thermal shutdown flag, and output short-to-VCC detection - all accessible through dedicated pins (IN, S_EN, MultiSense) and configurable via external sense resistor selection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

FAQ
What is the purpose of the S_EN pin on the VN7050AS-E board?
The S_EN pin is an active-high diagnostic enable input compatible with 3 V and 5 V CMOS logic. When asserted, it activates the MultiSense current-sense output; when deasserted, it disables OFF-state open-load detection to reduce system power consumption during sleep mode.
Can the VN7050AS-E drive inductive loads such as solenoids or relays?
Yes - the VN7050AS-E supports resistive, inductive, and capacitive automotive loads. Its integrated clamp diode, fast thermal transient limiting, and overvoltage protection (40 V transient rating) make it suitable for solenoid and relay driving with flyback energy management.
How is current sensing implemented on the VN7050AS-E board?
Current sensing uses the MultiSense pin, which outputs a proportional current (typically 1:2000 ratio) referenced to PGND. Users select RSENSE value (through-hole or SMD) across TP1–TP2 to set full-scale sense range and resolution per application requirements.
Does the VN7050AS-E require external components to operate?
No - the board includes all recommended external components per the VN7050AS datasheet: decoupling capacitors (C1, C2), pull-up resistors (R7, R8), and header connectors (J1–J4). Only the load, VBAT, and MCU control signals need connection for basic operation.
