Reversible motor driver

BA6287F

The BA6287F 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

VCRs and audio equipment in general

Features

1) Built-in power saving circuit suppresses the stop

mode current dissipation.

2) Output voltage can be set arbitrarily with the V

REF pin.

3) Interfaces with TTL devices.

4) Built-in thermal shutdown circuit.
