Abstract
In a case in which a malfunction occurs in a control processor which operates according to a predetermined program, a load-control backup signal generation circuit supplies a backup control signal to a switch of a load connected to an output of the control processor. The load-control backup signal generation circuit includes: a watchdog input terminal to which a watchdog signal periodically output from the control processor is input; a pulse count unit which counts a clock pulse generated with a constant period and which controls a count state of the clock pulse according to a signal input to the watchdog input terminal; and a signal selection unit which selects, from a plurality of options, a predetermined condition for causing a backup signal output unit to generate the backup control signal, based on a count output signal of a plurality of bits output from the pulse count unit.
