ABSTRACT:
A power switching control device for electric systems such as an ignition device for internal combustion engines has a control circuit IC and a switching IC. A temperature sensor is provided in the switching IC. The control circuit IC is joined to a grounding terminal through a conductive layer provided therebetween. Thus, the substrate potential of the control circuit IC is stabilized to the ground potential so that the temperature sensor is prohibited to operate erroneously due to electromagnetic noise.
