Abstract
When an electronic apparatus including a core chip and a hub controller chip is connected to an apparatus on the host side, a USB hub controller in the hub controller chip executes a process on a configuration between the USB hub controller and the apparatus on the host side and sets a limit value of power to be supplied, from a first limit value to a second limit value higher than the first limit value, and a VBUS current controller in the hub controller chip supplies the core chip with a power supply voltage generated based on a supplied power, which allows to maintain a configuration state between the apparatus on the host side and the USB hub controller at a time of starting up or at a time of class switching of the core chip and supply the core chip with the sufficient power.
