Problems solved by technology

In this way, when the TYPEC interface is in use, the double-sided wires are short-circuited, and the other unused usb2.0 communication line will cause the signal branch to be too long and affect the signal, resulting in usb2.0 communication failure
But there is currently no public solution

Abstract

The invention discloses a control circuit and a control method for shorting the front and back sides of a TYPEC. The control circuit includes: a comparator module and a switch module connected to each other; the switch module includes a first USB switch U3 and a second USB switch U4 The first USB switch U3 is connected between the positive plug communication lines of the TYPEC interface, and the second USB switch U4 is connected between the reverse plug communication lines; the input terminal of the comparator module and the positive plug of the TYPEC interface The CC1 line is connected, and the first USB switch U3 and the second USB switch U4 are controlled according to the output of the comparator module, so as to control the on-off of the forward-plug communication line and the reverse-plug communication line. The present invention controls the opening and closing of the first USB switch U3 and the second USB switch U4 according to the voltage of the positively inserted CC1 line, and then controls the on-off of the positively inserted communication line and the reversely inserted communication line, so that one of the USB2.0 Branch line cut.

Description

technical field [0001] The invention relates to the technical field of electronic equipment interfaces, in particular to a control circuit and a control method for short-circuiting the front and back sides of a TYPEC. Background technique [0002] At present, TYPEC has become the mainstream interface of consumer electronic products, and TYPEC of electronic products on the market has become the mainstream interface of electronic products. There are two sets of usb2.0 in the TYPEC, and some electronic products will connect both sets of usb2.0. In this way, when the TYPEC interface is in use, the double-sided lines are short-circuited, and the other unused usb2.0 communication line will cause the signal branch to be too long, which will affect the signal and cause the usb2.0 communication to fail. But there is currently no public solution. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the above shortcomings of the prior art, and to pr...
