is™ VY Biasing Unit Offset Cancellation Calibration Unit PV PC PD 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. 3901091204 Rev 003 Page 2 of 11 Data Sheet 16/Jan/12 MLX91204 360 Degrees Hi-Speed Rotary Position Sensor (Sine/Cosine) Table of Contents Functional Diagram ........................................................................................................................................................................... 2 General Description ........................................................................................................................................................................... 2 Glossary of Terms .............................................................................................................................................................................. 4 Absolute Maximum Ratings .............................................................................................................................................................. 4 Pinout and Function ........................................................................................................................................................................... 4 MLX91204 General Electrical Specification .................................................................................................................................... 5 MLX91204 Sensor Specification ...................................................................................................................................................... 5 Application Diagram .......................................................................................................................................................................... 7 8.1 Single Ended Mode ..................................................................................................................................................................... 7 8.2 Differential Mode ........................................................................................................................................................................ 7 9 Standard information regarding manufacturability of Melexis products with different soldering processes ...................... 8 10 ESD Precautions ............................................................................................................................................................................... 9 11 Package Information ....................................................................................................................................................................... 9 11.1 Package Dimensions ................................................................................................................................................................ 9 11.2 Pinout and Marking ................................................................................................................................................................ 10 11.3 Hall Plate Positioning.............................................................................................................................................................. 10 12 Disclaimer ................................................................................................................................................................................. 11 1 2 3 4 5 6 7 8 3901091204 Rev 003 Page 3 of 11 Data Sheet 16/Jan/12 MLX91204 360 Degrees Hi-Speed Rotary Position Sensor (Sine/Cosine) 3 Glossary of Terms • 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 Parameter.

Ageing ± 3.90 ± 3.10 Degree Incl. Ageing ± 4.90 ± 3.70 Degree 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, excentricity) design is not included and should be considered as an additional contribution. For more information, please refer to the application note: http://www.melexis.com/Assets/Magnet_Application_Note_MLX90316_5221.aspx 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.
