Abstract

PURPOSE:To simplify the constitution of a circuit by constituting a device which provides a detecting circuit, detecting a period for a primary current in an ignition coil to be limited to the predetermined value, and feeds back an output signal of a timer circuit, actuated in accordance with an output signal of the detecting circuit, to a current control circuit. CONSTITUTION:A drive circuit 4, which controls a power transistor 3 interrupting a primary current in an ignition coil 2 in accordance with an ignition signal from an ignition signal circuit 1, is provided. While providing a current detecting circuit 5 detecting the primary current in the ignition coil 2, a current control circuit 7 inputs an output signal of the circuit 5, comparing a detected current value with the reference voltage, limiting a primary current value of the ignition coil 2 to the predetermined value determined by the reference voltage. Detecting a period, in which this primary current is limited, by a current limiting period detecting circuit 8, the primary current is interrupted through the current control circuit 7 after the preset time of a timer circuit 6. While this primary current is interrupted, an output signal, similar to when the primary current is limited, is output from the detecting circuit 8.
