摘要
A power supply detection circuit detects power feeding to a VBUS terminal from the outside. A charger detection circuit detects the kind of charger by monitoring voltages of a DP terminal and a DM terminal. A control unit adjusts timing and instructs the charger detection circuit to start a charger kind detection process after a notification of detection of power feeding is received from the power supply detection circuit.
