Abstract
A current sensor circuit package includes a primary conductor having an input portion into which a current flows, an output portion from which the current flows, and an exposed portion, wherein the input and output portions have a reduced area edge. A secondary lead has an elongated portion that is offset with respect to the exposed portion of the secondary lead. A semiconductor die is disposed adjacent to the primary conductor on an insulator portion and at least one magnetic field sensing element is supported by the semiconductor die. A package body enclosing the semiconductor die and a portion of the primary conductor includes a first cutout in a first side edge configured to expose the reduced area edge of the input portion of the primary conductor and a second cutout on a second side edge configured to expose the reduced area edge of the output portion of the primary conductor, wherein the first side edge of the package body is substantially parallel with respect to the second side edge of the package body.
