Abstract
Hybrid magnetic current sensors and sensing apparatus are presented with closed-loop and open-loop circuitry employs first and second integrated magnetic sensors to sense a magnetic field in a magnetic core structure gap to provide high accuracy current measurement via a closed-loop magnetic circuit with the first sensor in a nominal current range as well as open-loop current measurement using the second sensor in an extended second range to accommodate over-current conditions in a host system as well as to provide redundant current sensing functionality.
