說明書
According to various embodiments, the electronic device may maintain a turned-on state without turning off the VBUS function of the booster 142 in consideration of subsequent reconnection with the external device 200 even when turning off the host block. The booster 142 may continuously supply VBUS power to the external device 200. In this case, according to various embodiments, the amount of power of the VBUS supplied from the booster 142 may be less than the amount of power in a state of being connected to the external device 200 for communication. In other words, when the host function is turned off, the electronic device may reduce the amount of power transferred to the VBUS.
According to an embodiment, when a specific event (e.g., a user input event through the input device 270 of
