Abstract
A device for detecting a leakage current generation condition in a universal serial bus (USB) interface including at least one pull-up circuit connected to the at least one power pin, and a port controller configured to detect at least one impedance between a ground pin and at least one power pin, detect a leakage current generation condition in the at least one power pin based on the at least one impedance detected, and activate a detection signal in response to the leakage current generation condition being detected, the port controller configured to detect the at least one impedance by controlling the at least one pull-up circuit to pull up the at least one power pin and detecting a voltage of the at least one power pin may be provided.
