Abstract
A power supply controller system includes a power supply portion, arithmetic processing portions, and first and second monitoring circuits configured to monitor an integrity of power supply of the power supply portion.

The second monitoring circuit instructs a first arithmetic processing portion to stop an operation thereof when a second watchdog timer is not reset for a predetermined period of time. The first monitoring circuit further includes a third watchdog timer periodically reset by any one of the first arithmetic processing portion and the second arithmetic processing portion and instructs another arithmetic processing portion to stop an operation thereof when the third watchdog timer is not reset for a predetermined period of time.
