General Description
The APX9358E 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 APX9358E is suitable for both game machine and CPU cooler that need silent drivers. It is available in VTDFN3x3-10 package.
