ABSTRACT:
The Hall generator integrated circuit in the transistor-controlled ignition system of an internal combustion engine and an integrated circuit board which carries the circuit elements for overvoltage protection, amplification, and the power output stage are mounted together in one building block. Preferably, the conductive element and the permanent magnet of the Hall generator are also integrated into the building block as is a pressure sensor. The output of the pressure sensor is directly applied to the circuits in the printed circuit board. The unit occupies little space and eliminates the need for external leads interconnecting the ignition coil and the output circuit.
