Abstract
A load control backup signal generating circuit for supplying a backup control signal to a switch of a load connected to an output of a control processor in a case that abnormality occurs in the control processor, includes a first input terminal that receives a constant period signal that is output periodically from the control processor when the control processor is normal, a constant period signal monitoring section that monitors a state of the constant period signal for identifying whether a length of the time during which a high or low level state of the constant period signal continues is longer than a predetermined time, and that outputs the signal corresponding to a result of the identification, and a backup signal output section that outputs the backup control signal when the output of the constant period signal monitoring section satisfies a predetermined condition.
