Embodiment 1

[0077] see image 3 , which shows an OTG function implementation device provided by an embodiment of the present invention, the device includes:

[0078] The receiving part is used to receive the first input signal and the second input signal according to the set receiving mode;

[0079] The conduction part is used to conduct the first input signal and the second input signal according to the conduction mode corresponding to the receiving mode to obtain the first output signal and the second output signal, and the first The first output signal is used for data transmission, and the second output signal is used for providing electric energy.

[0080] It should be noted that the two input signals and the two output signals are differential signals.

[0081] Further, such as Figure 4 As shown, the receiving part specifically includes: a first receiving port and a second receiving port for receiving the first input signal and the second input signal.

[0082] It can be unders...

Embodiment 2

[0110] Based on the same inventive concept of the foregoing embodiments, see Figure 9 , the present embodiment provides a method for implementing an OTG function, the method may include:

[0111] Receive the first input signal and the second input signal according to the set receiving method;

[0112] Conducting the first input signal and the second input signal according to the conduction mode corresponding to the receiving mode to obtain the first output signal and the second output signal, the first output signal is used for data For transmission, the second output signal is used to provide electric energy.

Abstract

Embodiments of the invention disclose an OTG function realization device. The device comprises a reception part and a breakover part, wherein the reception part is used for receiving a first-path input signal and a second-path input signal according to a set reception manner; the breakover part is used for breaking over the first-path input signal and the second-path input signal according to a breakover manner corresponding to the reception manner so as to obtain a first-path output signal and a second-path output signal; the first-path output signal is used for data transmission; and the second-path output signal is used for providing electric energy. The embodiments of the invention furthermore disclose an OTG function realization method.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of power supplies, and in particular to an OTG (On The Go, ongoing) function realization method. Background technique [0002] OTG technology is to realize data transmission between devices without a host. For example, a digital camera is directly connected to a printer, and through OTG technology, connects the USB ports between the two devices, and prints the photos taken immediately; the data in the digital camera can also be sent to a mobile hard disk with a USB interface through OTG Therefore, there is no need to carry an expensive memory card or carry a portable computer for field operations. [0003] With the development of science and technology, smart phones have become the center of personal information, and the functions of individual smart phone products are becoming more and more powerful, and OTG function is also a basic requirement. In the prior art, when the smart phone...
