Abstract

The invention provides a charging protocol handshake circuit and electronic equipment. The charging protocol handshake circuit comprises a controller, a delay circuit, a fast charging protocol circuit and a power access circuit, wherein the input end of the power access circuit is used for being electrically connected with an adapter, the first output end of the power access circuit is electrically connected with the signal end of the fast charging protocol circuit, and the second output end of the power access circuit is electrically connected with the input end of the delay circuit. The output end of the delay circuit is electrically connected with the power supply end of the fast charging protocol circuit, and the output end of the controller is electrically connected with the control end of the delay circuit. The problem that in the prior art, when a fast charger is connected to electronic equipment, handshake is not successful is solved.

Description

technical field [0001] The invention relates to the field of fast charging, in particular to a charging protocol handshake circuit and electronic equipment. Background technique [0002] In the market, there are various fast chargers, which can increase the charging current or charging voltage to realize fast charging of mobile phones, tablet computers and other electronic devices. In the existing design, the TYPE-C charging interface, its cable The core structure includes a power core and a signal core. The power core is longer than the signal core, which will cause a handshake failure when the adapter and the electronic device shake hands, so that the electronic device cannot be charged. . [0003] In view of this, propose this application. Contents of the invention [0004] The invention discloses a charging protocol handshake circuit and electronic equipment, aiming to solve the problem in the prior art that the handshake fails when a fast charger is connected to the...
