A power supply management circuit manages transfer of power that is supplied to a peripheral device from a power supply device. The power supply management circuit includes a current limiter and one or more capacitors. The current limiter limits intensity of first current received from the power supply device through an input terminal to be smaller than or equal to limitation intensity, and outputs second current having intensity limited to be smaller than or equal to the limitation intensity through an output terminal connected to the peripheral device. When the intensity of the first current exceeds the limitation intensity, the capacitors output third current through the output terminal.
