AM5669 Datasheet | BCD Semiconductor

Description The AM5669 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 independent precise voltage regulators with adjustable range from 1.5V to 4V and a free parator for spindle channel motor direction detection. The AM5669 is available in standard HSOP-28 package.
