Abstract
An ignition detector circuit includes first and second resistors connected in series between a primary winding of a coil and the ground, a comparator having a first input terminal connected to the junction between first and second resistors and a second input terminal to which a reference voltage is applied, and a capacitor and a third resistor connected in parallel between the first input terminal of the comparator and the ground.
