Datasheet Summary
AM8959 Motor Driver ICs
3-phase Sensor-less Fan Motor Driver
The AM8959 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 mutation current to the motor. Rotation speed can be controlled by PWM input signal. The drivers include SLOPE mode, STOP/RMI mode, Lock
Detection and Thermal Shutdown. Maximum output current is 1600mA.
