摘要：An internal combustion engine ignition device can determine ignition timing withhigh precision to perform ignition with high precision even where noise superimposed atthe time of rise of current flowing through an ignition coil is generated. In an internalcombustion engine ignition device including an output terminal for detecting an internal
state such as a coil current, it is possible to prevent generation of pulse noise in the formof chattering at falling and rising edges of a voltage of the output terminal by using ahysteresis comparator, even if noise is superimposed at the time of rise of the coilcurrent. Therefore, a voltage pulse with pulse width of high precision is transmitted to anelectronic control unit without the influence of noise, and the ignition timing can bedetermined properly with high precision.
