APX9281

APX9281 Single-Phase Full-Wave Motor Pre-Driver for Fan Motor Features Single Phase Fan Pre-Driver Low Supply Current Soft-Start Function Built-in Variable Speed Control Function Minimum Speed Setting Built-in Current-Limit Built-in Lock Protection and Auto Restart Function FG (Rotation Speed Dectection) Output Built-in Thermal Protection Circuit Lead Free and Green Devices Available (RoHS Compliant) General Description The APX9281 is a single phase, DC brushless motor pre-driver with features of PWM variable speed control, soft-start, and current-limit, which is suitable for fans, blowers, and pump motors. Adequate S-S pin capacitor could reduce the peak current at power on and Lock mode. PWM control system works depending on the comparison among the voltage of SET, MIN, and OSC. The device is equipped with built-in lock protection; when fan is locked, the device will enter the lockup protection mode. It is also with rotation detection output...
