3 Glossary of Terms
Gauss (G), Tesla (T): Magnetic flux density units where 1 mT = 10 G.
ADC: Analog-to-Digital Converter
TC: Sensitivity Temperature Coefficient (in ppm/Deg.C.).
Tria is
vertical (bulk & IMC) Hall plates. This technology allows the realization of Hall effect sensors able to sense
the flux density along the 3 axis (i.e. X, Y & Z) as well as position sensors able to sense 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 plate. Furthermore, it can provide some magnetic gain factor.
4 Maximum ratings
Table 1: Absolute maximum ratings
Exceeding the absolute maximum ratings may cause permanent damage. Exposure to absolute maximum
rated conditions for extended periods may affect device reliability.
