CD5888CB features
- 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.
- Wide dynamic range [9.0V (typ.) when Vcc1= Vcc2= 12V, at RL= 20Ω load].
- Separating power of Vcc1 and Vcc2 is to improve power efficiency by a low supply voltage for tracking, focus, and spindle.
- Level shift circuit built-in.
- Thermal shut down circuit built-in.
- Mute mode built-in.
- Dual actuator drivers: A general purpose input OP provides differential input for signal addition. The output structure is two power OPAMPS in bridge configuration.
- A general purpose input OP provides differential input for signal addition. The output structure is two power OPAMPS in bridge configuration.
- Sled motor driver: A general purpose input OP provides differential input for signal addition. The output structure is one power OPAMP in bridge configuration.
- A general purpose input OP provides differential input for signal addition. The output structure is one power OPAMP in bridge configuration.
- Spindle driver: Single input linear BTL driver. The output structure are two power OPAMPS in bridge configuration.
- Single input linear BTL driver. The output structure are two power OPAMPS in bridge configuration.
- Tray in-out driver: The DC motor driver supports forward/reverse control for tray motor.
- The DC motor driver supports forward/reverse control for tray motor.
- 2 Built-in regulator controllers Adjustable range 1.5V ~ 4V
- Adjustable range 1.5V ~ 4V
