SA5810 Datasheet, PDF (5/8 Pages) Silan Microelectronics Joint-stock – 5CHANNAL CD/DVD MOTOR DRIVER WITH POWER DOWN CONTROL

SA5810
The design of 1,2 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.
Output high level voltage (VOL+, VOL-), varied with the motor controller, it can output 3 times voltage of 3
pin, and in high level. In this time, the low level voltage input power pipe as the output saturation voltage.
