AM4406/4406F

2-PHASE HALF-WAVE HIGH VOLTAGE MOTOR PRE-DRIVER

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.

In addition, the AM4406 and AM4406F have RD and FG functions

respectively. The RD function is to detect the motor status and FG

function enables frequency generation.
