3D-magnetic field sensor

General Description

The FH3D02 is a dual 3D Hall sensor based on Fraunhofer HallinOne® technology. This versatile magnetic field sensor uses pure Hall effect principle without magnetizablematerials. FH3D02 offers accurate 3D magnetic field measurement at two positions with a planar IC in a 3x2x0.6mm WLCSP. It supports stray field robust applications by user selectable gradient measurement modes and contains integrated position / angle calculation. A variety of applications are support On Chip with the standard programming. With specific programming even more applications can be addressed.
