Abstract

To make is possible to use a peripheral device that consumes a current exceeding the rated current allocated to each port in a simpler system configuration in an electronic apparatus having a plurality of external interfaces. The electronic apparatus includes: a power source unit configured to supply a current to the external interfaces included in the electronic apparatus; a first power source control unit configured to guarantee a total current supplied for the two or more external interfaces and to perform current supply control for a specific external interface; and a second power source control unit configured to perform current supply control for the other external interfaces other than the specific external interface of the plurality of external interfaces by taking a current output from the first power source control unit as an input, and by the second power source control unit suspending current supply for the other external interfaces, the first power source control unit increases a current that can be supplied for the specific external interface.
