Abstract
Provided is a semiconductor circuit connected to a load circuit and configured to control power supply to the load circuit, comprising: a power line to which a power voltage is applied; an overvoltage protection unit that has an output unit configured to interrupt power supply from the power line to the load circuit when the power voltage in the power line is overvoltage; and a state notification unit configured to notify the outside of a state signal indicating whether the output unit is interrupting the power supply.
