Abstract:
1. A vehicle load backup device, comprising: an abnormality detection part which detects an abnormal operation of a processing part related to driving a load; and a backup driving part which drives the load based on an output from the abnormality detection part when the abnormality detection part detects the abnormal operation of the processing part; a reference voltage output part which outputs a reference voltage; and a comparison part which compares an output voltage from the abnormality detection part with the reference voltage from the reference voltage output part, and outputs a predetermined signal when the output voltage from the abnormality detection part is larger than the reference voltage from the reference voltage output part, wherein the abnormality detection part outputs a voltage smaller than the reference voltage when the processing part operates normally, and outputs a voltage larger than the reference voltage when the processing part operates abnormally; and wherein the backup driving part drives the load when the predetermined signal outputted from the comparison part is inputted into the backup driving part.
