Classification: CPC H | IPC H

Claim 6:
7. An electronic device, comprising:
a circuit including an input end, a first switch, a diode, an inductor and a capacitor, wherein the capacitor is electrically connected to the input end through the first switch and the first switch is electrically connected to the input end and the inductor; and
a circuit protection device, including:
a second switch;
a first current source electrically connected to the capacitor through the second switch; and
a detection and control unit, which turns on the second switch at a first time point so that the first current source charges the capacitor, detects a stored voltage value of the capacitor at a second time point, and compares the stored voltage value with a reference voltage value,
wherein, when the storage voltage value is greater than or equal to the reference voltage value, the detection and control unit turns off the second switch and turns on the first switch and, when the stored voltage value is smaller than the reference voltage value, the detection and control unit turns off the second switch and keeps the first switch off.
