Device Overview

Summary

A high-temperature H-bridge motor driver designed for DC motor control applications in automotive high temperature environments. With a maximum junction temperature of 200ºC, this driver is suitable for applications with an ambient temperature up to 150ºC. The IC includes four driver stages to control four external power MOSFETs. An external microcontroller provides the direction signal and the PWM frequency.
