  • Publication number: 20210127490
    Abstract: A power electronic assembly includes a board having metal layers laminated onto or between electrically insulating layers, and a power device embedded in the board. A first metal layer provides electrical contacts at a first side of the board. A second metal layer provides a thermal contact at a second side of the board. A third metal layer is positioned between the first metal layer and the power device and configured to distribute a load current switched by the power device. A fourth metal layer is positioned between the second metal layer and the power device and configured as a primary thermal conduction path for heat generated by the power device during switching of the load current. A first electrically insulating layer separates the fourth metal layer from the second metal layer so that the fourth metal layer is electrically isolated from but thermally connected to the second metal layer.

  • Patent number: 9564578
    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.
