360 Degrees Hi-Speed Rotary Position Sensor
(Sine/Cosine)
• Gauss (G), Tesla (T): Magnetic flux density units where 1 mT = 10 G.
• Tria is^®: This technology refers to the Melexis Hall technology which allows the realization
of Hall effect sensors able to sense the flux density along the 3 axis (i.e. X, Y & Z). In
particular, it enables the realization of position sensors able to sense the magnetic flux
density parallel to the IC surface and consequently the magnetic vector over 360 degrees.
• IMC: Integrated Magneto Concentrator. It concentrates the magnetic flux lines and bends
them at the extremity under the planar Hall plates. Furthermore, it provides some magnetic
gain factor.
4 Absolute Maximum Ratings

+6V
- 0.5 V
-40 to +125 Deg.C.
-40 to +150 Deg.C.
Exceeding the absolute maximum ratings may cause permanent damage. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
