Abstract

The invention provides a charging control circuit and electronic equipment capable of charging and discharging. The charging control circuit includes a first interface, an analog switch circuit, a control module and a second interface. The control module controls the analog switch circuit by outputting a level signal; when the analog When the switch circuit is in the state controlled by the first level signal, the control module is connected to the first interface and the second interface respectively; The switch circuit is switched from the state controlled by the first level signal to the state controlled by the second level signal. At this time, the control module disconnects the communication connection with the first interface and the second interface, and the data port in the first interface is connected to the second interface. The data ports in the second interface communicate directly, so that when the electric device sends a fast charging request, the external power source can charge the electric device quickly. The invention can solve the problem of too long charging time in the prior art when discharging while charging.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a charging control circuit and electronic equipment capable of charging and discharging. Background technique [0002] Mobile power is a commonly used electronic device. The existing mobile power usually has three functions: charging, discharging, and discharging while charging. Charging refers to charging the mobile power supply with a charging device (such as a fast charging adapter), discharging refers to charging the mobile power supply to an electrical device (such as a mobile phone), and charging while charging means that the charging device is charging the mobile power supply at the same time. Charge electrical devices. [0003] The existing mobile power supply, when charging and discharging at the same time, the mobile power supply always charges the electric device with a lower voltage (such as 5V). As the battery capacity of the current electric device (suc...
