Shut-off control device

A shut-off control device used in an in-vehicle system including:

• a power source unit;
• a power path through which power is transmitted between the power source unit and a load;
• a switch provided on the power path and configured to switch the power path between a current-carrying state and a current-interrupting state;
• and
• a shut-off unit configured to be switched from an allowing state to a shut-off state, the shut-off unit in the allowing state allowing power to be supplied from the power source unit to the load through the power path, and the shut-off unit in the shut-off state shutting off power supplied from the power source unit to the load,
• the shut-off control device comprising a control unit configured to switch the shut-off unit to the shut-off state when a value of a current flowing through the power path has exceeded a first threshold,
• wherein the first threshold is smaller than a second threshold that is the maximum current value at which the switch is capable of maintaining the power path in the current-carrying state.
