とする車載用電源回路。[Claims for Utility Model Registration] A battery 80, a first electrical component 50 to which the battery power is supplied when the accessory switch 85 connected to the battery 80 is on, and a second electrical component 50 to which the battery power is always supplied. An on-vehicle power supply circuit is provided with a noise cut filter for removing noise between the first and second electrical components 50, 60 and the accessory switch 8.
A single noise cut filter 4 provided between
0, and the noise cut filter 40 is directly connected to the first electrical component 50 and connected to the second electrical component 60 via a changeover switch 20. 40 and a second contact 22 directly connected to the battery 80, the detection voltage Vd output from the voltage detection section 30 detects the voltage on the electrical component side of the accessory switch 85. An on-vehicle power supply circuit characterized in that the first and second contacts 21 and 22 are brought into conduction depending on their presence or absence.
