AM5868S Features
1) Two comparators built-in:
Two general-purpose voltage open collector output comparators are built-in.
2) Two channels are voltage-type BTL drivers actuators of tracking and focus. Two channels 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= 20 load].
4) Separating power of Vcc1 and Vcc2 is improve power efficiency by a low supply voltage for tracking, focus, and spindle.
5) Level shift circuit built-in.
6) Thermal shut down circuit built-in.
7) Mute mode built-in.
8) Dual actuator drivers:
A general purpose input OP provides differential input for signal addition. The output structure is two power OPAMPS in bridge configuration.
9) Sled motor driver:
A general purpose input OP provides differential input for signal addition. The output structure is one power OPAMP in bridge configuration.
10) Spindle driver:
Single input linear BTL driver. The output structure are two power OPAMPS in bridge configuration.
11) Tray in-out driver:
The DC motor driver supports forward/reverse control for tray motor.
AM5868S Typical Application
BTL driver for CD, CD-ROM and DVD.
