UA8888S Description
The UTC UA8888S is a 5-channel BTL driver IC for DVD player. It is developed to driving the motors and actuators and consists of two independent precision voltage regulators with adjustable range from 1.5V~4V. LINEAR INTEGRATED CIRCUIT.
UA8888S Key Features
- Voltage-type BTL drivers
- two channels : actuators of tracking and focus
- two channels : sled and spindle motors
- one channel : bi-direction DC motor driver for tray
- Separating power of VCC1 and VCC2 is to improve power efficiency by a low supply voltage for tracking, focus, and spindl
- Built-in level shift circuit and mute mode
- Thermal shutdown protection
- Differential inputs for signal addition are provided by input OPs. The output structure for dual actuator driver is two
- Spindle driver is a single input linear BTL driver. The output structure is two power OP Amps in bridge configuration
- Tray in-out driver functions as a DC motor driver supports forward/reverse control for tray motor
