Abstract: A wireless charging circuit wirelessly receives power and includes a power receiving circuit that includes an inductor and a capacitor, a rectifier circuit that rectifies an alternating current voltage received from the power receiving circuit and outputs a rectified voltage, a regulating circuit that outputs a charging voltage that charges a battery using the rectified voltage, an overvoltage protection circuit connected in parallel between the rectifier circuit and the regulating circuit, and a controller that detects the rectified voltage and controls the overvoltage protection circuit. The overvoltage protection circuit includes first and second overvoltage protection circuits. By separating turn-on holding times of the first and second overvoltage protection circuits, the wireless charging circuit is effectively protected from overvoltage and damage to the circuit due to heat generation is prevented.
