Overview
Data Sheet 5-CHANNEL MOTOR DRIVER FOR DVD PLAYER General Description The AM5668 is a five-channel BTL driver IC, in which four channels are voltage-type BTL drivers for tracking and focus actuators, sled and spindle motors, the other one channel is DC motor driver for tray which supports forward/reverse control.
This IC also contains two general-purpose independent precise voltage comparators.
The AM5668 is available in standard HSOP-28 package.
