APX9358D中文资料Three-Phase Sine-wave Sensor-Less Fan Motor Driver数据手册Anpec规格书

描述 Description

The APX9358D 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 commutation control, Pulse Width Modulation (PWM) speed control, lock protection, and thermal shutdown circuit. The APX9358D is suitable for both game machine and CPU cooler that need silent drivers. It is available in VTDFN3x3-10 package.
