Abstract:
1. An integrated circuit, comprising: a lead frame portion having a plurality of leads; a current conductor portion comprising at least two of the plurality of leads; a substrate having first and second opposing surfaces, the first surface proximate to the current conductor portion and the second surface distal from the current conductor portion; one or more magnetic field sensing elements disposed proximate to the current conductor portion; a current sensing circuit disposed on the first surface of the substrate and coupled to the one or more magnetic field sensing elements, wherein the current sensing circuit is adapted to provide an output signal indicative of a current flowing through the current conductor portion; and an overcurrent circuit disposed on the first surface of the substrate, wherein the overcurrent circuit is adapted to sense a voltage drop associated with a current and further adapted to provide an output signal in response to the voltage drop, wherein the output signal is indicative of the current sensed by the overcurrent circuit being above a predetermined current.
