Electrical load i.e. motor vehicle blower motor, controlling device, has connection elements brought out from housing, and chip and resistance element, which are electrically connected by connection elements

摘要

The device has a shunt resistance element (20) arranged in a housing (12), and detecting current through a semiconductor chip (18). The element is thermally coupled with a metallic element (16), where the semiconductor chip and the shunt resistance element are equipped in an insulation material (14) of the housing. Drain, source and gate connection elements (24, 26, 28) of the transistor and connection elements (30-36) of the housing are brought out from the housing. The chip and the resistance element are electrically connected by the connection elements.
