Abstract
The return circuit of the ignition device returns to the battery the current supplied to the primary coil by the operation of the second circuit, and the voltage detection unit detects the voltage VB. The operation stopping unit monitors the voltage VB and when it is determined that the voltage VB is excessive, that is, when the voltage VB exceeds the threshold voltage VBc, it stops the supply of energy by the second circuit. As a result, when a load dump state occurs, the supply of energy by the second circuit can be stopped. Thus, when a load dump state occurs by the operation of the second circuit, other devices can be protected from overvoltage.
