Abstract
Methods and apparatus for measuring a current difference between at least two primary current paths in a current sensor integrated circuit package. Each primary current path generated a magnetic field which may then be measured by at least one magnetic field sensing element positioned on an integrated circuit die. An output disconnect signal may be provided from the current sensor integrated circuit package when a current difference above a predetermined threshold exists in the two or more current traces.
