The AM308 is a single phase full-wave fan motor driver IC with built-in hall sensor. Rotation speed can be controlled by PWM input signal. The device contains rotating speed pulse detection output (FG), output soft switching, lock protection and thermal shutdown protection. Maximum output current is 1A. The device is available in TSOT26-FL package.  
Single Phase DC Motor.
