AT5654 4-Channel BTL Motor Driver for CD-ROM

The AT5654 is a 4-channel BTL driver IC for driving the motors and actuators in products such as CD-ROM/DVD-ROM/DVD-Player drives. Two of the channels use current feedback to minimize the current phase shift caused by the influence of load inductance. Applications CD-ROM drives, DVD drives, DVD-ROM drives.
