5-CHANNEL BTL DRIVER FOR DVD PLAYER
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
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.
* Wide dynamic range: 9.
0V (typ.
