WATER RECOGNITION SYSTEM, ELECTRONIC DEVICE INCLUDING THE SAME, AND METHOD OF RECOGNIZING WATER THEREBY
First Claim
1. An electronic device comprising:
- a connector configured to connect to an external cable external to the electronic device, the connector comprising a plurality of pins;
a first water detection circuit connected to at least one first pin of the plurality of pins, the first water detection circuit configured to generate a first detection result based on a detected resistance of the at least one first pin; and
a second water detection circuit connected to at least one second pin of the plurality of pins, the second water detection circuit configured to,enter a water detection mode when the first detection result indicates the presence of water at the at least one first pin,generate a second detection result based on a detected resistance of the at least one second pin, anddetermine whether there is water in the connector based on the second detection result.

Abstract
An electronic device includes a connector connected to a cable external to the electronic device and including a plurality of pins; a first water detection circuit connected to at least one first pin of the plurality of pins and generating a first detection result by detecting whether there is water in the connector based on resistance of the at least one first pin; and a second water detection circuit connected to at least one second pin of the plurality of pins, entering a water detection mode when the first detection result indicates the presence of water, and detecting whether there is water in the connector based on resistance of the at least one second pin.

12. A method of recognizing water by an electronic device, the method comprising:
-
generating, by a first integrated circuit, a first detection result based on a resistance detected from at least one first pin of a connector of the electronic device, the connector comprising a plurality of pins; generating, by a second integrated circuit, a second detection result based on a resistance detected from at least one second pin of the connector, when the first detection result indicates that water is detected in the connector; and generating a first recognition result indicating that there is water in the connector, when the first and second detection results both indicate that water is detected. - View Dependent Claims (13, 14, 15)

21. A water recognition system comprising:
-
a configuration channel (CC) integrated circuit connected to a CC1 pin and a CC2 pin of a connector defined in a universal serial bus (USB) Type-C interface; and the CC integrated circuit configured to, receive, from outside of the CC integrated circuit, a first water detection result through a first pin of the connector, enter a water detection mode based on the first water detection result, and detect, through a second pin of the connector, whether water is present in the connector when in the water detection mode. - View Dependent Claims (22, 23, 24, 25)
