2-PHASE HALF-WAVE HIGH VOLTAGE MOTOR PRE-DRIVER
General Description
Features
Data Sheet
AM4406/4406F
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.

Note 1: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.
These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated
under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Maximum Ratings" for extended periods
may affect device reliability.
Note 2: Reduced by 5.5mW/oC when TA is over 25oC.
