Motor driver ICs

Reversible motor driver

BA6285FS / BA6285FP

The BA6285FS and BA6285FP are reversible-motor drivers 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) Logic and power sections have separate ground

pins; this allows the IC to drive speed-variable, re-

versible motors by connecting an electronic governor

circuit.

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.
