Abstract

An electronic device with a universal serial bus (USB) interface with an integration function comprises the USB interface, a processing unit, a power module, a main and auxiliary responding module and a power supply control module. The main and auxiliary responding module is connected between the USB interface unit and the processing unit and used for generating corresponding triggering signals according to the type of the electronic device connected with the USB interface. The processing unit is in communication connection with the electronic device through the USB interface. The power supply control module is connected between the power module and a voltage pin of the USB interface. When the processing unit receives a first triggering signal, the processing unit controls the power supply control module to forbid energy, and voltage connected into the voltage pin of the USB interface is used for charging the power module. When the processing unit receives a second triggering signal, the processing unit controls the power supply control module to output voltage to supply power to the electronic device connected with the USB interface. By means of the electronic device, only one USB interface is required to achieve data transmission and charging and discharging of the electronic device as a main device or an auxiliary device.

Description

technical field [0001] The invention relates to an electronic device, in particular to an electronic device with an integrated function USB interface. Background technique [0002] As we all know, general portable electronic devices, such as mobile phones, digital cameras, and tablet computers, all have USB (Universal Serial Bus, Universal Serial Bus) interfaces. The current portable electronic device can perform data communication with a host computer through a USB interface and charge at the same time. With the development of technology, USB OTG (USB On-The-Go) technology has gradually become popular. USB OTG technology allows two portable electronic devices to perform USB data transmission without going through the computer host, and one of the portable electronic devices is the main device. , another portable electronic device is the slave device. However, currently, when a portable electronic device is used as a master device or a slave device for data transmission wi...
