SA5888
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.

The design of 6,7 pin, consider the driver upper and lower unable ducting at the same time, be sure to do it, the
motor forward and reverse input by the open mode, and the interval of the open mode is more than 10ms.
