Abstract: Provided is an integrated circuit (41) that operates in normal mode or sleep mode corresponding to the on/off state of a vehicle engine. On the basis of information of setting data information stored in an internal register (42) and information of the on/off state of the vehicle engine from an MPU (50), the integrated circuit (41) generates monitoring signals (INZ0 to INZ7), monitoring signals (INA0 to INA7), and monitoring signals (INB0 to INB5). These monitoring signals enables to monitor states of a head light switch (11), a door switch (12), and a window switch (13). As the switch state monitoring method, intermittent operation or constant monitoring operation is performed.
