Exceeding the absolute maximum ratings may cause permanent damage. Exposure to absolute-

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
X⊥
and B

) proportional to the parallel components
(respectively B
X//
and 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. The third component B

is also sensed by those four (4) conventional Hall plates as shown
above.
