Zusammenfassung:An electronic device including a connector having a plurality of pins, and a detection circuit having at least one of a pull-up circuit and a pull-down circuit, and a connection circuit between a first pin and a second pin of the plurality of pins, the detection circuit is configured to select the first pin and the second pin, measure an impedance between the selected first pin and second pin by controlling a connection of the connection circuit and the at least one of the pull-up circuit and the pull-down circuit, and generate a detection signal indicating a presence or an absence of a foreign object on the connector based on the measured impedance.
