Abstract:
A semiconductor package includes a semiconductor die attached to a substrate and a magnetic field sensor included as part of the same semiconductor package as the semiconductor die and positioned in close proximity to a current pathway of the semiconductor die so that the magnetic field sensor can sense a magnetic field produced by current flowing in the current pathway. The magnetic field sensor includes a first magnetic field sensing component galvanically isolated from the current pathway and positioned so that a magnetic field produced by current flowing in the current pathway impinges on the first magnetic field sensing component in a first direction. The magnetic field sensor also includes a second magnetic field sensing component galvanically isolated from the current pathway and positioned so that the magnetic field impinges on the second magnetic field sensing component in a second direction different than the first direction.
