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

Features

General Description

Single-Phase Full Wave Fan Driver

The APX9277 is a single-phase full wave motor driver for

DC fan motors, and speed controlled by PWM input signal.

The output signals of this IC are the amplifications of hall

input signals. It is suitable for cooler DC fan that needs

silent drivers. The device has a built-in lock protection

function. When the fan is locked, the device will enter the

lockup protection mode. It also has the thermal shut-

down protection function. In normal operation, supply

current is less than 5mA, but in standby mode

(PWM=Low), it is just around 3mA. Moreover, this feature

will shut down the amplifiers and FG. The APX9277 is

available in MSOP-8 package.
