3-phase Sensor-less Fan Motor Driver
AM2355N
The AM2355N is a 3-phase sensor-less DC fan motor driver IC. It senses the BEMF (Back
Electro-Motive Force) of the motor in rotation and provides corresponding commutation current to
the motor. Rotation speed can be controlled by PWM input signal. The drivers include Lock
Detection, Thermal Shutdown, and Over-current Protection. Forward and Reverse control.
