Abstract:
Back-to-back power field-effect transistors with associated current sensors are disclosed. An example apparatus includes a first power field-effect transistor (FET) having a first source, and a second power FET having a second source. The first and second power FETs share a common drain. The first and second sources positioned on a first side of a substrate and the common drain positioned on a second side of the substrate opposite the first side. The example apparatus includes a current sensing FET positioned between a first portion of the first source of the first power FET and a second portion of the first source of the first power FET. The current sensing FET senses a current passing through the first and second power FETs.
