Abstract

The invention provides a charging control circuit and a chargeable and dischargeable electronic equipment; the charging control circuit comprises a first interface, an analog switch circuit, a controlmodule and a second interface, and the control module controls the analog switch circuit through outputting a level signal; when the analog switch circuit is in a first level signal control state, the control module is in communication connection with the first interface and the second interface. When an external power supply is connected to the first interface and electric equipment is connectedto the second interface, the analog switch circuit is switched from the state controlled by the first level signal to the state controlled by the second level signal, and at the moment, the control module disconnects the communication connection with the first interface and the second interface. And a data port in the first interface is directly communicated with a data port in the second interface, so that the external power supply can quickly charge the electric equipment when the electric equipment sends a quick charging request. The problem that the charging time is too long when chargingand discharging are carried out at the same time in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a charge control circuit and a chargeable and dischargeable electronic device. Background technique [0002] The mobile power supply is a commonly used electronic device. The existing mobile power supply 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 and discharging means that the charging device charges the mobile power supply at the same time as the mobile power supply. Charge electrical devices. [0003] Existing mobile power supply, when charging and discharging, the mobile power supply always charges the electrical equipment with a lower voltage (such as 5V). , resulting in longer and longer charging ...
