Abstract:
1. A power supply controller comprising: a semiconductor switch that is turned on and off for controlling power supply from a power source to a load; a determining section that determines whether an anomaly has occurred in a circuit including the semiconductor switch that is provided in the circuit; a controlling section that performs on-off control such that when the determining section determines that no anomaly has occurred, the controlling section causes the semiconductor switch to turn on and off and, when the determining section determines that the anomaly has occurred, the controlling section causes the semiconductor switch to maintain an off state; a monitoring section that monitors whether the controlling section itself is in a normal condition or whether the controlling section itself is in an anormal condition; an input section whereto an on-off command signal is externally input; and a switching section that, when monitoring result output by the monitoring section indicates the normal condition, causes the controlling section to perform on-off control and, when the monitoring result by the monitoring section indicates the anormal condition, causes the semiconductor switch to turn on and off on the basis of the on-off command signal input to the input section.
