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.
