Patent number: 7120808Abstract: Performing power saving control which can be inherited and standardized easily, and which keeps power devices from having to become larger is made possible. A current In flowing through an electrical path is detected as a voltage Vs by a current detection section, and is outputted as a voltage Vout by an amplifying section. When a level corresponding to the voltage Vout exceeds a limit level, a power limit detection section outputs a power limit detection signal. When a controller receives the power limit detection signal via a detection signal holding section, the controller outputs a throttle control command signal. When a chip set receives the throttle control command signal, the chip set initiates throttle control that lowers the clock frequency of a CPU. The present invention may be applied to laptop personal computers.Type: GrantFiled: October 3, 2003Date of Patent: October 10, 2006Assignee: Sony CorporationInventors: Atsushi Miyairi, Shinichi Numata, Katsuhiro Hashimoto, Shojiro Sato, Takaaki Morimura, Masataka Suzuki, Soichi Sato, Tamaki Kojima, Hidenori Yamaji
