| SMART MOTOR DRIVER WITH INTEGRATED HALL SENSOR
The UH255 is a single coil motor driver with integrated Hall
sensor.Lock-shutdown and auto-restart function protects the motor
from being over-heated and restarts the motor after being locked.
The rotation speed function is also integrated in the UH255, the
system could detect the rotation speed of motor when using
UH255 by the ‘FG’ pin.
The UH255 also uses Soft-switch phase-switching technique to
reduce the vibration and acoustic noise.
PWM is used for the speed control for UH255.Two types of
PWM input signals could be used: voltage mode PWM & pulse
* Soft switching output driver.
* Built-in Hall sensor motor driver.
* Motor lock protection and automatic restart.
* Thermal shutdown protection.
* PWM speed control.
