MAGNETIC FIELD CURRENT SENSORS

摘要

Current sensors, conductors and methods are disclosed. In an embodiment, a magnetic current sensor comprises a conductor comprising a first sheet metal layer having a first thickness and comprising at least one hole, 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 hole of the first sheet metal layer at least partially overlaps 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.
