Abstract: An ORing FET control circuit and method are provided. The circuit includes an ORing FET, a comparator, first, second and third resistors, a first capacitor, a diode and a driving unit. The positive and negative input terminals of the comparator are electrically connected to the input and output voltages. The first resistor, the second resistor, the first capacitor, and the third resistor are electrically connected in series between a reference voltage and a ground terminal sequentially. The reference voltage is lower than a voltage at the positive input terminal. When the input voltage is lower than the output voltage, if a voltage across the ORing FET is larger than a threshold, the comparator outputs a driving signal at low level, and correspondingly the driving unit turns off the ORing FET. The threshold depends on resistances of the first and second resistors.
