5-Channel BTL Driver - SL
Description
5-CH BTL DRIVER FOR DVD PLAYER WITH DISC BIDIRECTIONAL DRIVER AND TWO VARIABLE REGULATORS
DESCRIPTION
The SA5888 is a five-channel BTL driver IC for driving the motors and actuators in products such as CD - ROM / DVD drivers.
It is also build-in two independent precision voltage regulators with adjustable range from 1.
5V to 4V and one channel bi-direction DC motor driver for tray.
FEATURES
* Wide dynamic range (4.
0V (Typ.
) when VCC = 8V, PVCC =5V, and RL = 8 ).
* Level shift circuit on chip.
* Thermal shutdown circuit on chip.
* Mute mode built-in.
* Two regulator controllers built-in.
* Five drivers build-in: dual actuator drivers, sled motor driver, spindle driver and tray in-out driver.
* CD * CD-ROM * DVD
