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, Figure 2 and Figure 3), the magnetic flux density parallel to
the IC surface (i.e. B_//) is sensed through the Tria⊗is® sensor front-end. This front-end consists into two
orthogonal pairs (for each of the two directions parallel with the IC surface i.e. X and Y) of conventional
planar Hall plates (blue area on Figure 5) and an Integrated Magneto-Concentrator (IMC® yellow disk on
Figure 5).
