Overview

UNISONIC TECHNOLOGIES CO.
, LTD UH255 SMART MOTOR DRIVER WITH INTEGRATED HALL SENSOR CMOS IC  DESCRIPTION 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 mode PWM.
 FEATURES * Soft switchi...
