Title:
POWER SUPPLY CONTROL CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2024/018710
Kind Code:
A1
Abstract:
The present invention maintains the normal operation of a vehicle even if noise is superimposed on a power supply voltage and suppresses the increase in the size of a device. A power supply control circuit 1a includes: input terminals T21, T22 to which a DC power supply can be connected; a power supply line that supplies power from the input terminals to a next-stage circuit; a coil L400 provided in the power supply line; a first capacitor C400 connected between the input terminal side of the coil L400 and the ground line for the power supply line; a second capacitor C401 connected between the next-stage circuit side of the coil L400 and the ground line; a switch element Q303 that is connected in series with the power supply line and turns on or off the supply of power to the next-stage circuit; a monitoring circuit U310 that turns off the switch element Q303 when the voltage or current of the power supply line exceeds a threshold value; and a semiconductor element including a diode connected in parallel with the coil such that the cathode faces the previous-stage side of the coil L400 and the anode faces the next-stage side of the coil.
