ABSTRACT:
Two embodiments of an integrated ionization detection circuit and ignition coil driver, an ASIC and a single electronic package, are disclosed. The apparatuses reduce the cost and complexity of an in-cylinder ionization detection system by combining like functionality into one ASIC or electronic module easing packaging constraints. In both embodiments, a current sink is used. The current sink removes noise in the form of voltage splices. The voltage spikes are high voltage, but of short duration. The current sink prevents these spikes from turning on the IGBT. However, the current sink allows the IGBT command signal to pass. This device also comprises a switch whereby ionization current and coil primary current are multiplexed.
