description A pre-charging circuit and an electronic device are characterized in that the pre-charging circuit comprises a switch module, the switch module comprises a first switch, and when the first switch is switched off, a power supply module outputs a first voltage to a load module through the pre-charging circuit; when the first switch is closed, the power supply module outputs a second voltage to the load module through the pre-charging circuit, and the first voltage is smaller than the second voltage; the switch control module comprises a first comparator, the output end of the first comparator is electrically connected with the first end of the first switch and the first input end of the first comparator, the first comparator outputs a first level signal after a first time period, and the first level signal is used for controlling the first switch to be closed. According to the utility model, the output end of the first comparator is connected with the input end of the first comparator, and the first comparator
