APX9358P

Three-Phase Sine-wave Sensor-Less Fan Motor Driver

General Description

Features

PWM Quasi-Sinusoidal Driver

The APX9358P provides all the circuitry for sensor-less

speed control of three-phase brushless DC motor. The

Sine-wave Driver Method will be better low-noise. The

controller functions include start-up circuit, back-EMF com-

mutation control, Pulse Width Modulation (PWM) speed

control, lock protection, and thermal shutdown circuit.

The APX9358P is suitable for both game machine and

CPU cooler that need silent drivers. It is available in

VTDFN3x3-10 package.
