General Description
The FH3D02 is a dual 3D Hall sensor based on on Fraunhofer Institute for Integrated Circuits IIS HallinOne® technology. This versatile magnetic field sensor utilizes the pure Hall effect principle without magnetizable materials. The FH3D02 offers precise 3D magnetic field measurement at two positions with a planar IC in a 3x2x0.6mm WLCSP package. It supports applications requiring robust stray field handling through user-selectable gradient measurement modes and incorporates integrated position/angle calculation. A multitude of applications are supported On Chip with standard programming, with the potential for addressing even more applications with specific programming.
