Description
The UTC UA8888S is a 5-channel BTL driver IC for DVD player.
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 shu.
