Reversible motor driver

BA6288FS

The BA6288FS is a reversible-motor driver with a maximum output current of 1.0A. Two logic inputs allow four output

modes: forward, reverse, stop (idling), and brake. A built-in power saving circuit suppresses current consumption when

the motor is in stop mode.

Applications

Compact, low-current DC motors and portable equipment such as camcorders

Features

1) Two logic inputs allow four output modes: forward, re-

verse, stop (idling), and brake.

2) Built-in power saving circuit suppresses the stop

mode current dissipation.

3) Output voltage can be set arbitrarily with the V

REF pin.

4) Interfaces with TTL devices.

5) Built-in thermal shutdown circuit turns off all circuits

when high IC junction temperature is detected.
