Abstract

PURPOSE:To prevent ineffectiveness by discharging some hundreds of voltage across the conductors when a surge voltage over the set value is applied, which of an earth line and a power supply line are placed near an ignition signal generator input terminal conductor. CONSTITUTION:A combination integrated circuit is made up by a monolithic IC 1, a lead wire 2, a terminal lead wire 3, a thick-film resistor 4, a terminal conductive pattern 5, a power supply line conductive pattern 6, an earth line conductive pattern 7, a ceramic card 8, a Cu base 9, a power transistor 10, a molybdenum plate 11, and a ceramic card 12. The earth line conductive pattern 7 and the power supply line conductive pattern 6 are respectively placed near a pick-up coil p- terminal conductor and a p+ terminal conductor and each limit voltage is approximate 500V.
