Problems solved by technology

Although various portable devices have solved their own slow charging problem through the fast charging protocol, the following problems have also been introduced: 1. The various fast charging protocols based on the USBA interface are implemented in different ways, so they can quickly charge their own household appliances. The current power supply equipment cannot enable the power consumption equipment that supports other fast charging protocols to also realize the fast charging function.
Due to the different USB hardware interfaces used, the fast charging functions between the two devices cannot be used interoperably, forming a situation where the two fast charging and power supply devices stand on top of each other, resulting in an extreme waste of resources and bringing consumers great inconvenience

Abstract

The invention relates to a charging connection circuit integrated with a plurality of fast charging protocols, a chip and a charging connection device, which can rapidly charge the quick charging device according to the power supply capability of the quick charging adapter and the power demand of the quick charging device, thereby improving the universality of the circuit and the product. The charging connection device can be compatible with different types of fast charging adapters and fast charging devices, so that the fast charging devices can be quickly charged with different adapters.

Description

technical field [0001] The invention relates to the field of fast charging technology, in particular to a charging connection circuit, a chip and a charging connection device integrating multiple fast charging protocols. Background technique [0002] With the large screen of portable devices (such as mobile phones) and the operation of various large-scale software (such as large-scale 3D games), the corresponding battery capacity has also increased from a few hundred mAh in the early days to thousands of mAh now. Battery charging has become a bottleneck restricting the further development of portable devices. The current portable devices basically use the USB port for charging and discharging. Previous USB protocols include [USB1.0], [USB1.1], [USB BC1.2], [USB2.0], [USB3.0], etc., and the charging power of USB has been upgraded from 2.5W to 10.5W. The charging speed of the corresponding mobile phone is generally 5V / 1A, and the charging speed of the tablet computer is gene...
