Features

1) Two comparators built-in: Two general-purpose voltage comparators are built-in. 2) Two channels are voltage-type BTL drivers for actuators of tracking and focus. Two channels are voltage-type BTL driver for sled and spindle motors. It is also built-in one channel bi-direction DC motor driver for tray. 3) Wide dynamic range [9.0V (typ. ) when Vcc1= Vcc2= 12V, at RL=8Ω load]. 4) Separating power of Vcc1 and Vcc2 is to improve power efficiency by a low supply voltage for tracking, focus, and spin.
