General Description
   The APX9216 is a single phase full wave DC brushless motor driver with PWM variable speed control, current limit, and soft-start features suitable for the fan of personal computer’s power supply, CPU cooler and server. Adequate S-S pin capacitor could reduce the peak current at power on and lock mode. The PWM control system works depending on the comparison among the voltage of SET, MIN, and OSC.
