Single-Phase Full-Wave Motor Driver for Silent Fan Motor

Features

General Description

Single-Phase Full Wave Fan Driver

The APX9275A is a single phase full wave motor driver for

DC fan motors, and can apply to three type speed control

methods. The output signals of this IC are the amplifica-

tions of hall input signals. It is suitable for both game

machine and CPU cooler that need silent fans. The de-

vice is built-in lock protection, when fan is locked, the

device will enter the lockup protection mode. It is also

with thermal shutdown function. In normal operation, the

supply current is less than 8mA. The APX9275A is avail-

able in MSOP-10 and SOP-10 packages.
