Power Management IC Series for Automotive Body Control
Motor Driver
BD6941FM
No.09039EAT02
●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)
●Applications
Onboard devices(Vehicle equipment etc)
●Absolute Maximum Ratings（Ta=25℃）
