| Zusammenfassung: | The invention discloses a charging circuit of terminal equipment, the terminal equipment and a terminal system, and belongs to the field of electronic circuits. The charging circuit of the terminal equipment comprises a first switch, a processing unit, a temperature detection unit and a charging interface, the charging interface comprises a power input pin and a first signal pin, the first switch is connected between the first signal pin and a grounding end, and a control end of the first switch is connected with a first output end of the processing unit; the first input end of the processing unit is connected with the output end of the temperature detection unit; and when the first signal pin is connected and the temperature detection unit detects that the temperature of the charging interface is greater than the preset temperature, the processing unit disconnects the first signal pin and the grounding end by controlling the first switch, so that the power input pin can be powered off. The circuit can solve |
