Description
The Triaxis® rotary position sensor MLX91204
detects the absolute angular position of a small
magnet that is positioned above the device
surface.
The MLX91204 reports two analog, linear,
orthogonal (quadrature) and ratiometric output
voltages proportional to the applied magnetic flux
density parallel to the chip surface (thanks to the
Integrated Magneto Concentrator – IMC® – added
on the top of the sensitive Hall elements).
The MLX91204 is ideally suited for hi-speed rotary
position sensing in harsh automotive and
industrial environments.
The angular position is computed off-chip from
both sine and cosine signals.

2. Glossary of Terms
Gauss (G), Tesla (T): Magnetic flux density units where 1 mT = 10 G.
Triaxis®: 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.

The intrinsic linearity error refers only to the linearity error associated to the MLX91204. The linearity error
associated to the magnetic and mechanical (off-axis, eccentricity) design is not included and should be
considered as an additional contribution.
For more information, please refer to the application note:
https://www.melexis.com/en/documents/documentation/application-notes/application-note-mlx90316-
magnet-selection
The total error can be reduced either statically (room temperature compensation) or dynamically
(continuous compensation) through the off-chip signal processing performing the angular computation i.e.
arctan(Y_OUT/X_OUT). The compensation is applied prior to computing the arctangent function: offset, gain
and phase correction can be applied.

7. Recommended Application Diagrams
7.1. 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:
* 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.
7.2. 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)
For reliable operation within the specifications the sensor must be connected as follows:
* if the supply voltage is disturbed by EMI it can be useful to place a second capacitor (100pF ceramic)
parallel to the 100 nF capacitor.
