Patent ID: 8760149

Claim:
A magnetic current sensor comprising: a conductor comprising a first sheet metal layer having a first thickness and compromising at least one notch extending, inwardly from a first edge of the first sheet metal layer, and a second sheet metal layer having a second thickness less than the first thickness and comprising at least one notch, the second sheet metal layer being coupled to the first sheet metal layer such that the at least one notch of the first sheet metal layer is generally aligned with the at least one notch of the second sheet metal layer; and an integrated circuit (IC) die comprising at least one magnetic sensor element and being coupled to the conductor such that the at least one magnetic sensor element is generally aligned with a tip of the at least one notch of the second sheet metal layer, wherein a perimeter of the at least one notch of the second metal layer is generally contained within a perimeter of the at least one notch of the first metal layer such that the perimeters do not cross in tip regions of the notches.
