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 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 BX⊥ and BY⊥) proportional to the parallel components

(respectively BX// and BY//) 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 BZ is also sensed by those four (4) conventional Hall plates as shown

above.
