Preliminary Datasheet 5-CHANNEL MOTOR DRIVER FOR DVD PLAYER General Description
The AM5665 is a 5-channel BTL driver IC, in which two channels drive DC motor, two channels with current feedback drive the coils, such as the focus and the tracking actuator of DVD player, and the other one channel drives the bi-direction DC motor for tray. The AM5665 is available in standard HSOP-28 package.
