Overview
EUM6801 3-Phase Sensorless Fan Motor Driver DESCRIPTION EUM6801 is a 3-phase sensorless fan motor driver.
It senses the BEMF (Back Electromotive Force) of the motor in rotation and provides corresponding commutation current to the motor.
The sensorless technology doesn’t need Hall sensors.
The absence of the Hall sensor makes the fabrication of the motor easier, especially suitable for ultra-small motors.
EUM6801 integrates PWM speed control, soft switching, lock protection, auto restart, fan tachometer and forward/reverse functions.
As applying 3-phase driver method, PWM mode controls fan speed by adjusting duty cycle of PWM signal.
Internal soft switching function drives fan motor in low n...
