General Description
The APX9365D/E/F provides all the circuitry for sensorless speed control of three-phase brushless DC motor. The controller functions include start-up circuit, back-EMF commutation control, Pulse Width Modulation (PWM) speed control, lock protection, and thermal shutdown circuit.
The APX9365D/E/F is suitable for both game machine and CPU cooler that need silent drivers. It is available in VTDFN3x3-10 package.
