Abstract:
Provided are: a power supply control circuit having a configuration in which an N-channel FET and a P-channel FET can appropriately and selectively be used so as to control power feeding with high efficiency and at low cost; and a power supply control device including the power supply control circuit. An N-channel FET (NchFET in the drawings) and a P-channel FET (PchFET in the drawings) are connected in parallel with each other between the positive voltage side (+B) of a battery (direct current power supply) and a plurality of ECUs (loads) 4, 4, . . . , so as to appropriately control ON and OFF.
