ABSTRACT:
An ignition device for an internal combustion engine includes a transistor circuit used to turn a primary current of an ignition coil on and off to produce a high voltage for spark ignition. A reference voltage generator produces a temperature compensated reference voltage. A primary current detecting circuit produces a voltage corresponding to a primary current of the ignition coil. A comparator compares the temperature compensated reference voltage with the voltage produced by the primary current detecting circuit. A control circuit responsive to an output of the comparator controls a base voltage of the transistor circuit to a predetermined constant value.
