Motor driver ICs

Reversible motor driver

BA6289F / BA6417F

The BA6289F and BA6417F are reversible-motor drivers, with an output current of 600mA for the former and 1A for the

latter. 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.
