Abstract
A system and method for emulating an ideal diode for use in a power control device is provided. In one embodiment, the invention relates to a circuit for emulating an ideal diode, the circuit including at least one field effect transistor including a source, a drain, a gate, and a body diode, an input; an output coupled to the drain, a control circuit including a current sensor coupled between the input and the source, and a control circuit output coupled to the gate, wherein the control circuit is configured to activate the at least one field effect transistor based on whether the current flowing into the source is greater than a predetermined threshold, and wherein the body diode comprises an anode coupled to the source and a cathode coupled to the drain.
