| 11-FD216 Version : A.010 Issue Date : 2006/12/28 File Name : SP-FD216-A.010.doc Total Pages : 6 Brushless Vibrator Driver Built-in Hall Sensor 9 7 1 SILICON TOUCH TECHNOLOGY INC. 9-7F-1, Prosperity Road I, Science Based Industrial Park, Hsin-Chu, Taiwan 300, R.O.C. Tel886-3-5645656 Fax886-3-5645626 11-FD216 Brushless Vibrator Driver Built-in Hall Sensor General Specifications The device is designed specifically for brushless DC motor applications without any external components, such as vibrator, ultra-small blushless motor. Each device includes a HALL sensor, a lock detection circuit to shut down the driver output for the lock prevention, and complementary bi-directional drivers for driving and sinking coil load. If the motor rotation is stall by external forces or obstacles, the drivers will shut down roughly 0.5 to 2 seconds after the motor is locked. When the drivers shut down, the automatic self-restart circuit will try to power up the drivers every 0.5 to 2 seconds till the motor locking is released.
