General Description\nThe APX9270 is a single phase, DC brushless motor driver with PWM variable speed control and current limit features suitable for the fan of personal computer’s power supply and CPU cooler. The PWM control system includes thermistor input signal and direct PWM input signal, enabling highly silent and low vibration speed control. 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.
