ATA6824C数据手册集成电路（IC）的电机驱动器控制器规格书PDF

描述 Description

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.
