摘要：Problem to be solved: to provide a starting circuit capable of arbitrarily settingthe start determination value in a simple configuration and suppressing the interruptiontime delay. The starting circuit 20 mounted on the vehicle isIgnition signal input terminal21 to which ignition voltage Vig is appliedHigh potential line LH connected to ignitionsignal input terminalAn output terminal 22 for outputting an output voltage V1 andThecollector terminal is connected to the output terminalA PNP transistor Tr1 which outputsan output voltage V1 to an output terminal 22 when turned on;It is connected in oppositedirections between the high potential line LH and ground GNDA zener diode Z1 clamped

with a predetermined zener voltage VZ1A resistor R1 connected in series with the zenerdiodeA line L1 connecting the zener diode Z1 and the resistor R1 to the base terminal ofthe PNP transistor Tr1 is provided.Diagram
