Problems solved by technology

However, this kind of power supply security countermeasure requires both the interface port of the power supply end and the interface port of the power receiving end to support the USB power transfer specification to operate, but in the Type-C USB specification, it is not mandatory for the interface port to support the USB power transfer specification; if If one of the interface port of the power supply end and the interface port of the power receiving end does not support the USB power transfer specification, this power supply security mechanism cannot be implemented at all

Abstract

The present invention provides an electronic marker and related cables and methods. The electronic marker is applied to a cable electrically connected between a first interface port and a second interface port. The cable includes a configuration channel wire. The electronic marker includes: a first electronic marker arranged at the first interface port and electrically connected with a first powersupply pin of the first interface port and a second power supply pin of the second interface port; a second electronic marker arranged at the second interface port, wherein the first and second electronic markers comprise first and second active protection modules coupled to the configuration channel wire, any one of the first and second active protection modules can change the electrical features of the configuration channel wire when a preset event is generated to allow the first interface port to detect that the second interface port is not mounted.

Description

technical field [0001] The present invention relates to an electronic marking device and a related cable and method, in particular to a type-C USB (USB type C; USB type C; USB is the abbreviation of Universal Serial Bus, and the Chinese translation is called: Universal Serial Bus) electronic marker and related cables and methods. Background technique [0002] The USB Type-C specification is an emerging and widely used interface standard. It can not only support typical USB data interconnection (interconnection), but also develop a variety of power transmission options to supply power from one electronic product to another electronic product, such as Powered by a mobile power supply to a mobile phone, or from a computer host to a display, etc. USB Type-C power delivery options include: USB Specification Version 2.0 5V x 0.5A, USB Specification 3.1 5V x 0.9A, USB Battery Charging Version 1.2 5V x 1. 5A power supply (Type A USB connector), 5V x 1.5A power supply (Type C USB c...
