Abstract
A power switching device is provided with an integrated current sensor. The device includes component housing and multiple terminal legs extending therefrom. A current sensor assembly includes an interior cavity having a galvanically insulating tubular sleeve extending therethrough. A toroidal inductive winding resides within the first cavity and is circumferentially disposed about the sleeve, with one leg of the device defining a (single-turn) primary winding and the winding defining a secondary winding magnetically coupled to the device leg. Current sensing terminals are associated with respective locations along the inductive winding, wherein a current through the encapsulated terminal leg is detectable via respective current sensing leads extending from the assembly housing. A damping inductive element such as a ferrite bead may be provided within a second interior cavity defined by the assembly housing to suppress high frequency oscillations associated with a second (e.g., gate) terminal leg of the switching device.
