Exceeding the absolute maximum ratings may cause permanent damage. Exposure to absolute-maximum-rated
conditions for extended periods may affect device reliability.
6. Detailed Description
As described on the block diagram (Figure 1), the magnetic flux density parallel to the IC surface (i.e. B
is sensed through the Tria is
each of the two directions parallel with the IC surface i.e. X and Y) of conventional planar Hall plates (blue
area on Figure 3) and an Integrated Magneto-Concentrator (IMC
Both components of the applied flux density B
components (respectively B
are induced through the IMC and can be measured by both respective pairs of conventional planar Hall
plates as those are sensitive to the flux density applied orthogonally to them and the IC surface.
While a magnet (diametrally magnetized) rotates above the IC as described on Figure 2, the sensing
stage provides two differential signals in quadrature (sine and cosine
