APX9211

Single-Phase Full-Wave Motor Driver for Fan Motor

Features

General Description

Single Phase Full Wave Fan Driver

Low Quiescent Current (6mA Typical)

The APX9211 is a single phase full wave DC brushless

motor driver with PWM variable speed control, current

limit, and soft-start features suitable for the fan of per-

sonal computer’s power supply, CPU cooler and server.

Adequate S-S pin capacitor could reduce the peak cur-

rent at power on and lock mode. The PWM control sys-

tem works depending on the comparison among the volt-

age of SET, MIN, and OSC. The device is equipped with

a built-in lock protection, which protects the fan when it is

locked. It also has rotation speed detection output and

thermal protection function. The APX9211 is available in

SSOP-16 and TSSOP-16P packages (see Pin

Configuration).
