2-PHASE HALF-WAVE HIGH VOLTAGE MOTOR PRE-DRIVER AM4406/4406F

Data Sheet

Nov. 2009 Rev. 1. 5 BCD Semiconductor Manufacturing Limited

General Description

The AM4406/4406F are 2-phase, half-wave motor pre-

drivers 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 automat-

ically 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.

The AM4406/4406F are available in SOIC-8 package.
