Abstract
A current sensor includes a lead frame having a plurality of leads, at least two of which form a current conductor configured to carry a current that generates a magnetic field and a substrate having first and second opposing surfaces, the first surface proximate to said current conductor and the second surface distal from the current conductor. A first magnetic field transducer is disposed on the substrate and a first coil is disposed on the substrate adjacent to the first magnetic field transducer, wherein the first magnetic field transducer and the first coil are positioned on a first side of the current conductor. A second magnetic field transducer is disposed on the substrate and a second coil is disposed on the substrate adjacent to the second magnetic field transducer, wherein the second magnetic field transducer and the second coil are positioned on a second side of the current conductor.
