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.

8) 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 1.25V ~ 4V

12) A free comparator

For spindle motor back emf detection
