Abstract:
An integrated circuit package includes an encapsulation and a lead frame. A portion of the lead frame is disposed within the encapsulation. The lead frame includes a first conductor forming a first conductive loop. A second conductor is galvanically isolated from the first conductor. The second conductor forms a second conductive loop proximate to and magnetically coupled to the first conductive loop to provide a magnetic communication link between the first and second conductors. A signal that is transmitted from a transmit circuit coupled to the first conductor is coupled to be received through the magnetic communication link by a receive circuit coupled to the second conductor.
