Abstract

The invention discloses a USB-TYPE-C-based charging device with a HUB function. The charging device comprises a power supply module, a BC1.2 protocol module, a DC-DC converter circuit, a TYPE-A interface, a TYPE-C female seat interface, a TYPE-C USB3.1 interface, a main control MCU and a switch. The main control MCU is connected to the TYPE-C female seat interface and the TYPE-C USB3.1 interface; and the switch is controlled by the main control MCU. When the charging device charges an external electrical device, the USB2.0 / 3.0 / 3.1 data transmission with the electrical device can be realized.

Description

technical field [0001] The invention belongs to the technical field of charging consumer electronic products, and in particular relates to a USB-TYPE-C combined with HUB function charging device and method. Background technique [0002] In 2015, after the laptop MacBook released by Apple changed to USB Type-C interface and removed the original Thunderbolt interface, USB Type-C immediately became the focus of public attention. Because of the powerful function of the TYPE-C port, the whole MacBook has only one port, which makes the MacBook thinner and simpler, and has won the favor of countless users. The practice of having only one TYPE-C interface for the whole machine has also attracted many manufacturers to follow suit. [0003] Because of the powerful TYPE-C interface, TYPE-C products only need one interface to realize all functions, and it is also because TYPE-C products only have one TYPE-C interface, which makes their versatility worse. A very simple example, assumin...
