The MLX90367 is sensitive to the three components of the flux density applied to the IC (i.e. BX, BY and BZ). This allows the MLX90367 with the correct magnetic circuit to decode the absolute position of any moving magnet (e.g. rotary position from 0 to 360 Degrees or linear displacement, stroke). It enables the design of novel generation of non-contacting position sensors that are frequently required for both automotive and industrial applications. MLX90367 provides SENT Frames encoded according the Throttle sensor format or Secure Sensor format. The circuit delivers enhanced serial messages providing error codes, and user-defined values. MLX90367 Triaxis® Position Sensor IC Datasheet Contents Features and Benefits................................................................................................................................ 1 Applications............................................................................................................................................... 1 Description ................................................................................................................................................ 1 1.

For instance, in case of a rotary position sensor application, Thermal Offset Drift #1 equal ± 60LSB 15 yields to max. ± 0.3 Deg. angular error for the computed angular information (output of the DSP). This is only valid if k = 1. 8 For instance, in case of a rotary position sensor application, Thermal Drift of Sensitivity Mismatch equal ± 0.5% yields to m ax. ± 0.15 Deg. angular error for the computed angular information (output of the DSP). 9 The Intrinsic Linearity Error refers to the IC itself (offset, sensitivity mismatch, orthogonality) taking into account an id eal rotating field for BX and B Y. Once associated to a practical magnetic construction and the associated mechanical and magnetic t olerances, the output linearity error increases. However, it can be improved with the multi -point end-user calibration. The intrinsic 7 Linearity Error for Magnetic angle  XZ and  YZ can be reduced through the programming of the k factor. 10 Noise pk-pk (peak-to-peak) is here intended as 6 times the Noise standard Deviation.

Melexis strongly recommends storing this value during the EOL (End-Of-Line) programming to ensure full traceability of the final product. These parameters shall never be erased during the EOL programming.

Above 70 mT, the IMC starts saturating yielding to an increase of the linearity error. 13 Below 20 mT, the performances slightly degrade due to a reduction of the signal -to-noise ratio, signal-to-offset ratio. 14 This is the magnetic gain linked to the Integrated Magneto Concentrator structure. This is the overall variation. Within one lot, the part to part variation is typically ± 10% versus the average value of the IMC gain of that lot. 12 TH REVISION 7.0 – FEB, 8 2019 Page 12 of 39 MLX90367 Triaxis® Position Sensor IC Datasheet 13.

A diagnostic (analog/environmental) detects an error (15) 2. The reporting of the above error is enabled (16) 3. The debouncing time has elapsed. Diagnostic Reporting, Channel 1 The diagnostic can be reported through the 12 bit payload of channel 1, and not only through the status bit Status[0]. The EEPROM parameters SERIALERROR controls the diagnostic reporting through channel 1 as follow: If SERIALERROR =0, the channel 1 reports the angle, and not the diagnostic, as if no diagnostic. The error is reported only thanks to the Status bits. If SERIALERROR >0, the channel 1 payload contains the value Channel1 = (4088 + SERIALERROR]) Diagnostic Reporting Time The Diagnostic Reporting Time is programmable (defined as multiple of a macro -cycle unit time). A macro-cycle is a sequence of 20 angle acquisitions and has duration of approximately 6ms. Diagnostic Debouncing The Diagnostic Reporting is debounced. The debouncing parameters are user-programmable, by steps of approximately 6 ms. Pause pulse A pause pulse, as defined by the standard, is present at the end of every frame. The pause pulse mode can be disabled. Please contact our Direct Sales team to obtain the complete procedure for deactivating the pause pulse mode. The pause pulse length is adjusted by the circuit so that the frame period is constant. The field sensing and the frame synchronization pulse are in sync.

Example $809 = GainOOS + ADCsatura 14.4. Start-up During the chip initialization, the output remains high until the circuit emits four initialization frames (all 6 data nibbles are zero). The fifth frame is not an initialization frame but a valid frame containing a measured angle. See also section 8 “Timing Specification”. The first four frames conform to the SENT specification and include a valid CRC. 14.5. Field sensing (A2D conversions) and the frame Synchro pulse By default setting of the Timer period and Filter =1, the digital angle (fast channel payload) results of the average of two angles. These angles are themselves computed from 4 ADCs values. The time between the ADCs and the frame synchronization pulse is constant. As a result, the phase delay between the magnetic field angle and the SENT synchronization pulse is constant, allowing filtering at the ECU side.

The shape of the MLX90367 transfer function from the digital angle value to the output voltage is described by the drawing below. Six segments can be programmed but the clamping levels are necessar ily flat. Two, three, or even five calibration points are then available, reducing the overall non -linearity of the IC by almost an order of magnitude each time. Three or five point calibration will be preferred by customers looking for excellent non-linearity figures. Two-point calibrations will be preferred by customers looking for a cheaper calibration set-up and shorter calibration time. 100% CLAMPHIGH Clamping High Slope LNR_C_S C LNR_C_Y Slope LNR_B_S B LNR_B_Y Slope LNR_A_S A LNR_A_Y Slope LNR_S0 Clamping Low CLAMPLOW 0% 0 (Deg.)

The CLAMPHIGH parameter sets the maximum output voltage level. Both parameters have 16 bits of adjustment and are available for both LNR modes. 15.1.6. Thermal Ouput Offset correction (AxX version only) On the AxX version, the two parameters ANGLEOFSSLOPEHOT and ANGLEOFSSLOPECOLD, defined in the section End-User Programmable Parameters, enable adding an offset to the output dependent on the measured temperature (see the Figure 10).

The span of this offset is +5.62/-3.37% of the full output scale. The added thermal offset varies with temperature see the equation below and the thermal coefficient is defined separately before (used coefficient ANGLEOFSSLOPECOLD) and after 35Deg.C (used coefficient ANGLEOFSSLOPEHOT).

SMISM, k and SEL_k Parameters (i) SMISM When the mapping (B1=X, B2=Y) is selected, SMSIM defines the sensitivity mismatch factor that is applied on B1 or B2; When another B1, B2 mapping is selected, this parameter is “don’t care”. This parameter is trimmed at factory; Melexis strongly recommends TO NOT overwrite it for optimal performances. (ii) K When the mapping (B1=X, B2=Y) is NOT selected, k defines the sensitivity mismatch factor that is applied on B1 or B2 (according to parameter SELK – see below). When the mapping (B1=X, B2=Y) is selected, this parameter is “don’t care”. This parameter is trimmed at factory for mapping (B1=Z, B2=X). Melexis recommends to fine trim it when a smaller linearity error (Le) is required and a different mapping than (B1=X, B2=Y) is selected. (iii) SELK When the mapping (B1=X, B2=Y) is NOT selected, SELK defines the component on which the sensitivity mismatch factor k (see above): SELK = 0 means B1 k  B1 and SELK = 1 means B2  k  B2. 15.4.3. GAINMIN and GAINMAX Parameters GAINMIN and GAINMAX define the thresholds on the gain code outside which the fault “GA IN out of Spec.” is set. If GAINSATURATION is set, then the virtual gain code is saturated at GAINMIN and GAINMAX, and no Diagnostic fault is set since the saturations applies before the diagnostic check. 15.5.
