AM8959 Motor Driver ICs 3-phase Sensor-less Fan Motor Driver AM8959 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 commutation 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.  Features 1) Operation voltage 3.
