Embodiment Construction

[0039]In order to illustrate the foregoing and other purposes, features and advantages of the invention, the embodiments and figures of the invention will be described in detail as follows.

[0040]Certain terms are used throughout the description and following claims to refer to particular components. As one skilled in the art will appreciate, manufacturers may refer to a component by different names. This document does not intend to distinguish between components that differ in name but not function. In the following description and in the claims, the terms “include” and “comprise” are used in an open-ended fashion, and thus should be interpreted to mean “include, but not limited to . . . ”. The term “substantially” means the value is within an acceptable error range. One skilled in the art can solve the technical problem within a predetermined error range and achieve the proposed technical performance. Also, the term “couple” is intended to mean either an indirect or direct electric...

Abstract

An electronic device for communicating with an external device includes a connector, a controller, a first switch element, a second switch element, a first voltage source, a second voltage source, a third voltage source, and a fourth voltage source. When the external device is coupled to the connector, the connector receives a device existence voltage from the external device. The controller generates a first control signal and a second control signal according to the device existence voltage. The first switch element couples the first voltage source or the second voltage source to the connector according to the first control signal. The second switch element couples the third voltage source or the fourth voltage source to an output node according to the second control signal.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This Application claims priority of Taiwan Patent Application No. 107109048 filed on Mar. 16, 2018, and further claims priority of Taiwan Patent Application No. 107114861 filed on May 2, 2018, the entirety of which is incorporated by reference herein.BACKGROUND OF THE INVENTIONField of the Invention[0002]The disclosure generally relates to an electronic device, and more particularly, to an electronic device for communicating with an external device.Description of the Related Art[0003]Current electronic devices can be coupled with a variety of external devices. However, since these external devices have different standards, they may not be compatible with some electronic devices, and this limits the uses and applications thereof. Accordingly, there is a need to propose a novel solution for solving the problems of the prior art.BRIEF SUMMARY OF THE INVENTION[0004]In an exemplary embodiment, the invention is directed to an electronic device ...
