VNH7070ASTR
Overview
The VNH7070ASTR is an integrated H-bridge motor driver designed for driving bidirectional brushed DC motors in automotive and industrial applications. It operates from a wide 4V to 28V supply range and can deliver up to 15A of output current, featuring a fully integrated control and power stage in a compact SO-16N package.
Why Choose This Part
This driver integrates comprehensive diagnostics, including analog motor current feedback and detection for short-to-ground or short-to-Vcc conditions. Its cross-conduction protection and undervoltage shutdown ensure system robustness, while the low 1uA standby current maximizes battery life in idle states.
Applications
Key Specifications
Getting Started
Designers should interface the INA, INB, and PWM pins with a microcontroller to manage direction and speed control. Use the CS pin to monitor the analog current feedback and ensure appropriate thermal sinking on the SO-16N package for high-current operation up to 15A. STMicroelectronics provides the EV-VNH7070AS evaluation board to expedite prototyping and thermal validation.
