Abstract

The invention provides a charging circuit and a control method and a control device thereof. The charging circuit is used for charging mobile equipment in different brands. The control circuit comprises a general interface which is connected with the mobile equipment to be charged, a charging adaptive unit which comprises at least two types of charging circuits, is connected with the general interface and is used for providing the corresponding charging circuits to the mobile equipment, a voltage converting unit which is connected with a charging source and is used for adjusting the output voltage of the charging source to the charging voltage of the mobile equipment, and a current detecting unit which is connected between the voltage converting unit and the charging adaptive unit, and is used for detecting the charging current which is used for confirming the charging circuit corresponding to the mobile equipment. By adopting the technical solution of the invention, the mobile equipment in different brands can be charged through one general interface, and can be charged through the mobile equipment, thus the use of the mobile equipment is convenient.

Description

technical field [0001] The invention belongs to the field of mobile equipment products, and more specifically relates to a charging circuit and a control method and device thereof. Background technique [0002] UFI products and PAD products are more and more favored by consumers, and the battery capacity of these two types of products is also increasing. In the future, the mainstream will be above 4500mAh. With plenty of electricity, consumers want to charge other mobile devices, such as smartphones. Smartphones are limited by their size, and their batteries are often below 2000mAh, so they will run out of electricity soon. If there is no mains power, it will be similar to outdoor charging. , you can charge your smartphone through UFI or PAD products for emergency use. [0003] At present, different brands of mobile terminals on the market have slightly different charging detection methods. Some mobile terminals add different voltage values ​​to the data lines DP and DM. Wh...
