Abstract

See full text

It is disclosed an electronic device to control an ignition coil of an internal combustion engine, comprising a high-voltage switch, a driving unit, a bias circuit and an integrating circuit. The high-voltage switch is connected in series with a primary winding of a coil. The driving unit is configured to control the closing and opening of the high-voltage switch. The integrating circuit is interposed between the bias circuit and a reference voltage. The integrating circuit comprises an integrating capacitor connected in series to the bias circuit and connected between the bias circuit and the reference voltage. The integrating capacitor is configured to maintain a substantially null charge during a phase of measurement of a ionization current as to measure a substantially null value of an integral of the ionization current, in the case of a misfire of the comburent-combustible mixture.
