Abstract

The invention discloses a multi-split wire for realizing data transmission of any path, and the circuit comprises a USB input interface which is used for receiving input data; at least two switch control circuits connected with the USB input interface; wherein the switch control circuit comprises a power switch circuit and a data switch circuit; at least two load detection and data reading units,wherein the load detection and data reading units are respectively connected with an output interface so as to complete the output of a detection result and data reading; and a main control module isconnected with each load detection and data reading unit and each switch control circuit. According to the invention, the power supply and data output by a certain branch of the wire rod can be closedor opened as required to realize control; meanwhile, a multi-port output current detection circuit is arranged, so that whether each path has data connection, removal, full charging and closing of acorresponding output port or not can be judged; the functionality allows multi-branch free data transmission and selection of whether to charge.

Description

technical field [0001] The invention relates to a data transmission circuit, in particular to a multi-channel data transmission control circuit of a USB interface. Background technique [0002] Now the USB interface is widely used to realize device charging, data transmission and transfer equipment, but most of the existing transfer cables are one out of two, that is, one uplink C port and two downlink A ports. ; or one out of three, that is, one uplink C-port and three downlink A-port data lines, the charging mode can only be switched by connecting to the device status of the uplink port, bidirectional charging is not supported, and data transmission is also one-way transmission. To sum up, there are currently two main methods for data transmission and charging: 1) One-to-one wires, the input and output of the wires are only one way, which can realize data transmission and fast charging, but the wire interface is single and requires multiple 2) One-to-many cables, generall...
