Abstract
In an electronic device, a monitoring circuit monitors a voltage change with regard to each of an RX2+ terminal and an RX2− terminal in a state where a charging device is connected to a Type-C connector. A determining circuit determines whether a short-circuit between a VBUS terminal and the RX2+ and RX2− terminals has occurred using the voltage change at each of the RX2+ terminal and the RX2− terminal.
