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 providedwwbw.yDatianShpeuet4tU.OcomPs.
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
HSOP-28
*Pb-free plating product number: UA8888SL
