The invention discloses a charging circuit and a mobile terminal. The charging circuit comprises a wireless communication module, a wireless charging control module and a wired charging control module. The wireless communication module is electrically connected with an external charging module through the wireless charging control module. The wired charging control module is electrically connected with the charging module and the wireless communication module. The wireless charging current flows into the wireless communication module and then the wireless communication module controls the wireless charging control module to be conducted and the wireless charging current flows into the charging module so as to establish a wireless charging circuit. The wired charging current flows into the wired charging control module and then the wired charging control module is conducted and the wired charging current flows into the charging module so as to establish a wired charging circuit. Meanwhile, the wired charging control module controls the wireless communication module to be off so that the wireless charging circuit is enabled to be off. Priority selection of wired charging and wireless charging can be realized by controlling on / off of the wireless communication module so that the circuit is simple in structure and convenient to implement.
Description
technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a charging circuit and a mobile terminal. Background technique [0002] At present, the applications of various mobile terminals such as mobile phones and tablet computers are becoming more and more popular, and have become necessities of people's life. The rapid development of mobile terminals in recent years has accelerated people's demand for battery life. This demand undoubtedly stimulates the development of wireless charging technology and promotes the rapid development of the wireless charging product market. Its prospects are widely recognized in the industry. look good. [0003] Although wireless charging has the advantage of not needing to plug and unplug the charging cable, it also faces the limitation of charging distance. Therefore, based on the advantages of the wired charging and the wireless charging, the mobile terminal usually adopts a configuration in...
