UA8888S
LINEAR INTEGRATED CIRCUIT
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.
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.) when VCC1= VCC2= 12V, at RL= 20Ω load.
4.0V (typ.) when VCC1=12V,VCC2=5V,at RL=15Ω load
* Separating power of VCC1 and VCC2 is to improve power
efficiency by a low supply voltage for tracking, focus, and spindle.
* 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 power OP
Amps in bridge configuration, and one OP Amp for Sled Motor
Driver.
* 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.
* Built-in regulator controllers: Adjustable range 1.5V ~ 4V
