APX9280

APX9280 Single-Phase Full-Wave Motor Pre-Driver For Fan Motor Features General Description Single Phase Fan Pre-Driver Low Supply Current Built in Variable Speed Control Function Hall Bias Circuit included Minimum Speed Setting Built-in Current-Limit Built-in Lock Protection and Auto Restart Function FG (Rotation Speed Detection) and RD (Lock Detection ) Output Built-in Reactive Current Cut Circuit Built-in Thermal Protection Circuit Lead Free and Green Devices Available (RoHS Compliant) The APX9280 is a single phase, DC brushless motor pre-driver with features of PWM variable speed control and current-limit, which is suitable for fans, blowers, and pump motors. The right ROFF resistor value could tune the adequate soft switch time to cut reactive current before phase changes. PWM control system works depending on the comparison between the voltage of SET, MIN, and OSC. The device is equipped with built-in lock protection; when fan is lo...
