とマイコン等の制御回路を駆動する第2の電源電圧とを
具備し、電源スィッチの開成時に前記第2の電源電圧の
立下りを第1のスイッチング素子で検出し、該第1のス
イッチング素子の出力で第2のスイッチング素子を導通
させて前記第1の電源電圧を急峻に立下ることを特徴と
する電源回路。The device includes a first power supply voltage that drives peripheral devices such as a control motor, and a second power supply voltage that drives a control circuit such as a microcomputer, and when the power switch is opened, the fall of the second power supply voltage is set to a second power supply voltage. 1. A power supply circuit characterized in that the first switching element detects the voltage, and the output of the first switching element causes a second switching element to conduct, thereby causing the first power supply voltage to fall steeply.
