Features
- 1) 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. 2) Wide dynamic range [9.0V (typ. ) when Vcc1= Vcc2= 12V, at RL= 20Ω load]. 3) Separating power of Vcc1 and Vcc2 is to improve power efficiency by a low supply voltage for tracking, focus, and spindle. 4) Level shift circuit built-in. 5) Thermal shut down circuit built-in. 6) M.
