Abstract
A first power source line disposed between a positive electrode side of an electricity storage unit and a first external terminal, a second power source line disposed between a negative electrode side of the electricity storage unit and a second external terminal, a power source circuit connected to both the first and second power source lines and configured to supply an output voltage to a control circuit in an operating state, a power source control circuit configured to control an operating state and a non-operating state of the power source circuit, a first control signal generation circuit configured to supply a first control signal corresponding to transition of an external voltage applied to the first external terminal and the second external terminal to the power source control circuit to set the power source circuit in an operating state for a prescribed time, and a second control signal generation circuit configured to generate a second control signal that allows the power source circuit to be set in an operating state continuously by the control circuit to which an output voltage of the power source circuit is supplied are included.
