3 Glossary of Terms
MLX91204
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.

8 Application Diagram
8.1 Single Ended Mode
The output voltages X = (X_OUT – GND) and Y = (Y_OUT – GND) are within 0.5V to 4.5V with an
offset of 2.5V (VDD/2)
For reliable operation within the specifications the sensor must be connected as follows:
+5V
100 nF*

* if the supply voltage is disturbed by EMI it can be useful to place a second capacitor (100 pF
ceramic) parallel to the 100nF capacitor.
8.2 Differential Mode
The output voltages X = (X_OUT – CO_OUT) and Y = (Y_OUT – CO_OUT) are within ±2 V around
“virtual ground” (i.e. CO_OUT = 2.5V = VDD/2)
