Bus power device and power-source control method |
摘要 |
A bus power device includes a connector that is connected to a port of a host apparatus compliant with a predetermined interface standard; a current/voltage detecting unit that detects a current/voltage supplied from the host apparatus to a bus power line via the port and the connector; and a power assisting unit that assists a current to the bus power line based on a result of comparison between the current detected by the current/voltage detecting unit and a threshold current, and assists a voltage to the bus power line by an amount of shortfalls in the voltage based on a result of comparison between the voltage detected by the current/voltage detecting unit and a threshold voltage.
