Power Management IC Series for Automotive Body Control

Motor Driver

BD6941FM

●

Description

BD6941FM is the reversible motor driver for output 1.25A (1Motor), and can control a DC motor in four modes (Forward,

Reverse, Standby, Brake) corresponding to two control logic inputs.

●

Features

1) １ch DMOS H bridge output

2) Four output states ( Forward,Reverse,Standby,Brake ) by two control logic

3) Built-in surge-absorbing diodes

4) Low standby current

5) Output overcurrent protection with timer.

6) Over voltage detection switch off

7) TSD detects junction temperature and circuitry switches off the outputs at high temperature.

8) Built-in protection monitor pin (PO)
