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) Mute mode built-in.
7) Dual actuator drivers:
A general purpose input OP provides differential input for signal addition.
The output structure is two power OPAMPS in bridge configuration.
8) Sled motor driver:
A general purpose input OP provides differential input for signal addition.
The output structure is one power OPAMP in bridge configuration.
9) Spindle driver:
Single input linear BTL driver. The output structure are two power
OPAMPS in bridge configuration.
10) Tray in-out driver:
The DC motor driver supports forward/reverse control for tray motor.
11) 2 Built-in regulator controllers
Adjustable range 1.5V ~ 4V
