Abstract: A first circuit and a second circuit, which have different operating voltages, are connected through a level shifter, and a combination circuit below is provided in the level shifter. An enable signal, which is switched between active and inactive states according to whether or not a potential is supplied to a second high potential power line, is applied to the combination circuit. The combination circuit outputs a first signal and a second signal, which is acquired by logically inverting the first signal, to a level shift circuit according to an output signal of the first circuit, in a case where the enable signal is active, and causes both the first signal and the second signal to be at a low level in a case where the enable signal is inactive.

Abstract: A power source control circuit includes a USB power supply portion that supplies electric power from a power source circuit to a secondary battery, a solar power supply portion, and a monitoring circuit. A monitoring circuit causes a solar power supply portion to stop the supply of the electric power to the secondary battery if the electric power is supplied from the power source circuit. In this way, if both the power supply by the power source circuit and the power supply by power generation by the solar cell can be performed, the power source control circuit can charge the secondary battery from the power source circuit which is a stable power source, and thus, it is possible to easily secure the electric power for driving the system.
