Abstract

Embodiments related to magnetic current sensors, systems and methods. In an embodiment, a magnetic current sensor integrated in an integrated circuit (IC) and housed in an IC package comprises an IC die formed to present at least three magnetic sense elements on a first surface, a conductor, and at least one slot formed in the conductor, wherein a first end of the at least one slot and at least one of the magnetic sense elements are relatively positioned such that the at least one of the magnetic sense elements is configured to sense an increased magnetic field induced in the conductor proximate the first end of the at least one slot.
