Beschreibung
Zusammenfassung:	A semiconductor device includes a power supply circuit which generates an output voltage to be supplied to a USB device connected to a USB connector, a sensing circuit which senses an output voltage or an output state of the power supply circuit, a control circuit which controls the power supply circuit, and a register which stores an output set voltage value associated with the power supply circuit or various types of information. The control circuit outputs a notification signal based on a result of sensing by the sensing circuit to the outside.
