AM4406/4406F 2-PHASE HALF-WAVE HIGH VOLTAGE MOTOR PRE-DRIVER ADVANCED INFORMATION Description Pin Assignments The AM4406/4406F are 2-phase, half-wave motor predrivers fabricated for fan motors. These ICs are equipped with lock shutdown and automatic restart functions. The lock shutdown function turns off the output current when the motor is under lock condition. And when the motor is unlocked, the ICs will automatically restart and allow DC fan to run.

A motor lock condition is detected when the Hall signal stops switching. The output is ON when CT pin is being charged. C2 is the external capacitor of the CT pin. Output ON time and OFF time are determined by the capacitance of C2. Note 6: RD pin is ON during normal operation, and OFF when the motor is locked. It is an open collector output pin.
