Abstract

The invention provides a charging control circuit and charging circuit of a mobile terminal and electronic equipment. The mobile terminal comprises a peripheral interface and a charging controller, the peripheral interface comprises two charging terminals, and the charging controller comprises an output end and two input ends. The charging control circuit comprises a terminal detection circuit anda switching circuit, the input end of the terminal detection circuit is connected with the output end of the charging controller, the switching circuit is positioned between the two input ends of thecharging controller and the two charging terminals, and each charging terminal is connected any one input end of the charging controller; and the output end of the terminal detection circuit is connected with the control end of the switching circuit. The charging control circuit is additionally arranged between the peripheral interface and the charging controller, and the problem that a Type-C interface cannot be plugged in two directions is solved.

Description

technical field [0001] The embodiments of the present invention relate to the charging field, and in particular to a mobile terminal charging control circuit, a charging circuit and electronic equipment. Background technique [0002] Smartphones have become an indispensable tool in daily life, and their importance is increasing day by day. The power consumption of smart phones has become a common problem in the industry, and the convenience of charging has increasingly become one of the directions that users care about. [0003] Due to the single direction of the common Micro-USB interface type charging interface earlier, the user needs to align the direction to successfully insert the charging head into the mobile phone, which brings great inconvenience to the user. In order to change this situation, the Type-C interface came into being. The biggest feature of the Type-C double-sided pluggable interface is that it supports double-sided insertion of the USB interface, which...
