| Zusammenfassung: | The utility model discloses a load power supply control circuit and electronic equipment. The load power supply control circuit comprises a switch branch, a detection branch and a controller. The first end of the switch branch is connected with the controller, the second end of the switch branch is connected with the first end of the first power supply, the second end of the first power supply is connected with the first end of the load, the third end of the switch branch is connected with the second end of the load, and the detection branch is connected with the controller. The controller is used for outputting a control signal. The switch branch comprises a coil, the switch branch is used for responding to the control signal to be conducted so as to establish connection between the first end of the first power source and the second end of the load, and the coil is powered on when the switch branch receives the control signal. The detection branch is used for outputting a first level signal to the controller |
