Electronic device supporting USB interface and control method for USB interface
First Claim
1. An electronic device comprising:
- a housing;
a display device exposed through a first part of the housing;
a recess formed in a second part of the housing;
a receptacle formed in the recess;
a plurality of conductive contacts disposed inside the receptacle and including a first contact;
a first circuit configured to supply and/or receive a current of a first level or larger to and/or from the first contact when an external connector is inserted into the receptacle;
a first switching device comprising switching circuitry configured to electrically connect the first circuit with the first contact or to interrupt an electrical connection between the first circuit and the first contact;
a second circuit configured to detect existence of a foreign object comprising moisture contacting the first contact while the external connector is inserted into the receptacle; and
a control circuit configured to control the first switching device based at least in part on information regarding the detected existence of the foreign object comprising moisture, wherein the control circuit is a toggling circuit, and wherein the control circuit is configured to control the first switching device so as to toggle between allowing the first circuit to apply, and not apply, a current or a voltage to the first switching device.

Abstract
An electronic device includes a housing, a display device exposed through a first part of the housing, a recess formed in a second part of the housing, a receptacle formed in the recess, a plurality of conductive contacts disposed inside the receptacle and including a first contact, a first circuit that supplies and/or receives a current of a first level or larger to and/or from the first contact when an external connector is inserted into the receptacle, a first switching device that electrically connects the first circuit with the first contact or to interrupt a connection between the first circuit and the first contact, a second circuit that detects existence of a foreign object contacting the first contact while the external connector is inserted into the receptacle and a control circuit that controls the first switching device based at least in part on information regarding the detected existence of the foreign object.

15. A method of controlling an operation of an electronic device, the method comprising:
-
detecting existence of a foreign object comprising moisture contacting a first contact disposed inside a receptacle if an external connector is inserted into the receptacle including a USB interface; controlling a switching device based at least in part on information regarding the detected existence of the foreign object comprising moisture; applying a current of a first level or larger to the first contact under control of the switching device; and wherein the controlling the switching device comprises controlling, by a control circuit, the switching device so as to toggle between applying, and not applying, a current or a voltage to the switching device. - View Dependent Claims (16, 17, 18, 19)
