Abstract
Current sensors, conductors and methods are disclosed. A magnetic current sensor includes a conductor including a first sheet metal layer having a first thickness and including 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 including 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 including 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.
