Abstract
The present disclosure provides a semiconductor device in which shortening of system rise time is achieved. A power supply system conformed to a USBPD standard includes: a plurality of USB ports; a common power supply unit common to the plurality of USB ports; a plurality of power supply units corresponding to the plurality of USB ports, a plurality of controllers corresponding to the plurality of USB ports; and a management unit executing allocation of maximum power to be assigned to the plurality of USB ports in accordance with signals from the plurality of controllers. The management unit determines whether surplus power is generated in maximum power assigned to a first USB port by execution of the allocation of the maximum power and, when surplus power is generated, increases the maximum power assigned to a second USB port.
