VNH5019
Overview
The VNH5019 is a high-current full-bridge motor driver designed for a wide range of automotive and industrial applications. It integrates a dual monolithic high-side driver and two low-side switches, providing a compact solution for bidirectional control of brushed DC motors. The device operates from 5.5V to 24V and can deliver up to 30A of continuous output current.
Why Choose This Part
The VNH5019 provides comprehensive protection features including undervoltage shutdown, overvoltage shutdown, and cross-conduction protection. It features an integrated current sense output proportional to the motor current and a charge pump output to facilitate reverse polarity protection. The device is AEC-Q100 qualified and output-protected against shorts to ground and VCC, ensuring high reliability in harsh environments.
Applications
Key Specifications
Getting Started
To evaluate this IC, engineers often use carrier boards from manufacturers like Pololu which break out the MultiPowerSO-30 pins to a standard 0.1 inch header. When designing a custom PCB, ensure large copper planes are connected to the power tabs for effective heat dissipation at high current levels. Control is achieved through standard PWM and CMOS compatible logic inputs for direction and speed.
