5. Absolute Maximum Ratings
Exceeding the absolute maximum ratings may cause permanent damage.
maximum-rated conditions for extended periods may affect device reliability.
6. Detailed Description
As described on the block diagram (Figure 1 and Figure 2), the magnetic flux density applied to the IC 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 (sensitive
element – blue area on Figure 4) and an Integrated Magneto-Concentrator (IMC® yellow disk on Figure
4).
Two orthogonal components (respectively B
(respectively B
conventional planar Hall plates as those are sensitive to the flux density applied orthogonally to them and
the IC surface. The third component B
