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.

Water recognition system, electronic device including the same, and method of recognizing water thereby

A water detection circuit includes a voltage detector electrically connected to at least one first pin of a connector and configured to detect a first voltage level from the at least one first pin at a first point in time and a second voltage level from the at least one first pin at a second point in time, a detection logic configured to compare the first voltage level with a first threshold and compare the second voltage level with a second threshold and a power controller configured to block current from being supplied to the at least first pin before the second point in time, after the first water detection operation is completed, wherein the detection logic determines that water is present in the connector when water is detected in at least one of a first water detection operation and a second water detection operation.
