Problems solved by technology

In other words, even if the OTG host has a strong load capacity, it cannot provide a larger charging current.
However, in the case that the current battery capacity generally exceeds 3000mAh, charging with a current specification of 500mA is extremely slow, and basically has no practical value.
[0011] To sum up, when the existing terminal equipment supplies power externally, the power supply current is small and the charging speed is extremely slow

Abstract

The invention discloses a terminal device and a control method thereof. The terminal device comprises a USB interface and a USB controller. The USB interface comprises two signal pins. The control method comprises the following steps of receiving a switching instruction, switching the connection states of the two signal pins between a USB standard downstream port SDP state and a dedicated charging port DCP state according to the switching instruction, wherein the SDP state is a state that the two signal pins and a USB controller are connected, and the DCP state is a state that the two signal pins are in a mutual short connection. The connection state of the two signal pins of the USB interface are switched between the SDP state and the DCP state, the switching of the USB interface between SDP and DCP types is realized, when switching to the DCP type, terminal equipment can supply power outward with large current, the charging speed is raised, and the technical problem of a slow charging speed in outward charging of the terminal equipment is solved.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a terminal device and a control method thereof. Background technique [0002] Universal Serial Bus (USB) powering portable devices has become a standard application along with its serial communication function. Today, USB power delivery has been extended to battery charging, wall adapters and other forms of power applications. A notable effect brought by the popularization of applications is that the charging and power supply of portable devices can be interchanged with plugs and adapters. As a result, current solutions allow multiple power sources to be used for charging, as opposed to past architectures that used dedicated adapters for each device. [0003] Taking USB2.0 as an example, there are 5 pins (PIN) in the USB2.0mini interface, including: [0004] A pair of power pins: VBUS / GND [0005] A pair of signal pins: D+ / D- [0006] One master-slave identificat...
