2-channel reversible-motor driver

BA6191

The BA6191 is a 2-channel motor driver for CD player changers and electric volume switches, among other applications.
Because it uses a negative power supply, this IC uses the power supply of application products efficiently.

Applications
CD player, etc.

Features

1) Two-channel reversible-motor driver.

2) Four modes - forward, reverse, stop (free rotation)
and brake are output according to control logic input
