2-channel reversible-motor driver

BA6193

The BA6193 is a 2-channel motor driver for CD player changers and electric volume switches, and other applications

as well. Because it uses a negative power supply, this IC uses the power supply of application products efficiently.

FApplications

CD players and CD-ROM drives with loading features, etc.

FFeatures

1) Reversible-motor driver with dual independent chan-

nels.

2) Four modes forward, reverse, stop (free rotation)

and brake are output according to control logic input

(two inputs).

4) Internal power supply voltage drop mute circuit.

5) Internal thermal shutdown circuit.

6) Negative power supply.
