GENERAL DESCRIPTION
FEATURES
Data Sheet AM4406/4406F 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. In addition, The AM4406/4406F are available in SOIC-8 package.● Hall Inputs with a Hysteresis
