Abstract

The invention relates to a TYPE-C interface one sub-two conversion circuit. The TYPE-C interface one sub-two conversion circuit comprises a TYPE-C male plug, a first TYPE-C female plug, a second TYPE-C female socket, a power switch control circuit, a control circuit and an earphone control circuit, wherein the TYPE-C male plug is connected with a mobile terminal, the first TYPE-C female socket isconnected with a charging adaptor, the second TYPE-C female socket is connected with an earphone, the control circuit is used for controlling the charging adaptor to charge the mobile terminal by thepower switch control circuit and also controlling the mobile terminal or the charging adaptor to supplying power to the earphone, and the control circuit is further used for controlling an A6 end andan A7 end of the TYPE-C male plug to be circuit-shorted or circuit-opened by the earphone control circuit so as to perform DP and DM control. By the TYPE-C interface one sub-two conversion circuit, the mobile terminal can be charged by the charging adaptor as well as the earphone is inserted, and the circuit is simple and is low in cost and small in size.

Description

technical field [0001] The invention relates to the technical field of TYPE-C, and more specifically relates to a TYPE-C interface one-to-two conversion circuit. Background technique [0002] TYPE-C interface is the latest generation interface released by the USB Association. The highlights of the new version interface are slimmer design, faster transmission speed (up to 10Gbps) and more powerful power transmission (up to 100W), Type-C double-sided The biggest feature of the pluggable interface is that it supports double-sided insertion of the USB interface, which officially solves the worldwide problem of "USB can never be plugged in correctly", and can be plugged in at will. [0003] At the same time, the USB data cable used with it must also be thinner and lighter, and can be used to transmit audio, video, and power signals. After years of development, TYPE-C earphones are becoming more and more popular in electronic equipment. With the popularity of the C port, more and...
