Abstract: A digitally based resistance element and a processor are used with a hotwire to provide a mass airflow (MAF) sensor. A temperature sensor can provide an input to the processor which can provide signals to the digital based resistance element. The digital based resistance element may be on a first leg of a Wheatstone bridge, the hotwire on a second leg. The output of the hotwire may be provided to the processor which can modify the output such as to more closely approximate a MAF curve, and/or to address step changes initiated by the digital based resistive element.

Abstract: A voltage regulator controls voltage supplied from a generator or alternator and includes a voltage regulator body having at least one component receiving cavity. A lead frame is embedded within the voltage regulator body and forms external lead frame connectors and internal lead frame connectors. A voltage regulator integrated circuit and passive components are mounted within the at least one component receiving body and connected to the selected internal lead frame connectors. The lead frame can be configured such that one or more passive components are positioned over or under at least a portion of the voltage regulator IC.
