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 1.25V ~ 4V

12) Under voltage detection
