PROBLEM TO BE SOLVED: To automatically restore a power feeding device to an operation in a sound state before microprocessor runaway.;SOLUTION: This power feeding device 1 with a built-in microprocessor (CPU) 21 is configured to feed power to a load 9. The CPU 21 executes control to: perform the distributed write of the operation-related information of the power feeding device 1 in a plurality of storage areas R1 to RN in each predetermined cycle in a sound state that no runaway detection signal is transmitted; read the plurality of operation-related information 41a1 to 41aN [(figure 2 (not shown))] from an RAM 33 according to a runaway detection signal from a watch dog timer circuit 23; judge the operation-related information of the sound state on the basis of the matching state of the operation-related information 41a1 to 41aN; and automatically restore the power feeding device 1 to the sound state on the basis of the operation-related information in the healthy state.;COPYRIGHT: (C)2005,JPO&NCIPI
