Embodiment Construction

[0030] The design concept of the present invention is: to solve the problem that the electronic equipment in the prior art cannot manage the power supply of the USB interface according to the application scene of the USB interface, the USB_ID pin and the USB_ON pin of the USB interface are detected by the MCU, and sorted out After the corresponding logical relationship, send control commands to the charging management chip, so as to control the charging management chip to control the USB interface to output the corresponding voltage and input the corresponding current according to the different USB devices connected to the USB interface. The configuration of the input and output states of the USB interface is adaptively completed, thereby saving system power consumption, improving the performance of electronic equipment, and optimizing user experience.

[0031] figure 1 It is a flow chart of a charging management method for a USB interface according to an embodiment of the pre...

Abstract

The present invention discloses a charging management method of a USB interface, and an electronic device. The method comprises that a micro control unit MCU of the electronic device detects level status of a USB_ID pin and a USB_ON pin of the USB interface of the electronic device, when the level status of the USB_ID pin or the USB_ON pin are detected to be changed, the MCU transmits a corresponding control instruction to reconfigure an operating mode of a charging management chip of the electronic device, so that the charging management chip controls the USB interface to output corresponding voltage or input corresponding current. According to the technical scheme, the USB interface is controlled to output the corresponding voltage or input the corresponding current according to different scenes of USB interface application, performance of the electronic device is improved, and user experience is optimized.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a charging management method of a universal serial bus (USB) interface and electronic equipment. Background technique [0002] At present, many electronic devices are equipped with standard USB interfaces for charging, information interaction and OTG (On-The-Go). When the USB interface is connected to different USB devices (eg, USB charging adapter, computer), there are corresponding requirements for the power supply of the USB interface. For example, when connecting a charging adapter, a large current is required for charging input; when connecting to a computer or other host computer, it is necessary to limit the small current charging input and activate the USB communication function; when connecting an OTG device, it is necessary to provide external DC power; Turn off the power output, etc. However, in the prior art, there is no solution for managing the power ...
