MLX90367 Triaxis® Position Sensor IC
Datasheet
The MLX90367 is a monolithic sensor IC sensitive
to the flux density applied orthogonally and
parallel to the IC surface.
Features and Benefits
.
.
Triaxis® Hall Technology
On Chip Signal Processing for Robust Absolute
Position Sensing
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.

1 Averaged current consumption, for the dual version, the supply current is multiplied by 2.
2 To reach 10mA, the power saving option is enabled. This option switches off and on internal blocks dynamically. It can be dis abled
in case of extreme emission requirements; the maximum supply current consumption is then increased up to 12mA.
3 The specified value is valid during early start-up time only; the current might dynamically exceed the specified value, shortly,
during the Start-up phase.

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 BY. 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
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. The application diagram used is described in
the recommended wiring. For detailed information, refer to section Filter in application mode (Section 15.5).

11 The condition must be fulfilled for at least one field BX or BY.
12 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.

14.2.2. Diagnostic Reporting through the fast channel
Diagnostic Reporting, bit Status[0]
The bit Status[0] is high whenever the three following conditions are met:
REVISION 7.0 – FEB, 8TH 2019
Page 16 of 39
MLX90367 Triaxis® Position Sensor IC
Datasheet
1. 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.
Fast Channel CRC
The MLX90367 features the new recommended implementation and optional the legacy implementation

Table 3 - Serial Message Sequence
The first part (positions 1 to 24) provides the Error Code and the Sensor ID alternatively.
The second part (positions 25 to 40) is optional and enabled with EEPROM bit( EE_ExtendedSequence=1)..
This second part consists of the error code (8 occurrences), and 8 OEM -defined Code
The temperature can be derived from SENT ID 23, TEMP sensor, with the following equation:
SENT@ ID 23 = 8 * (T[C] – 35[C]) + 865 LSB12
The accuracy of the actual Temperature is around ± 10 Deg.C.

In case multiple errors occur, then the resulting 12 bit enhanced serial message data will be the OR-
operation of the individual data values. 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 LNR parameters, together with the clamping values, fully define the relation (the transfer function)
between the digital angle and the output signal.
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 necessarily 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.

All the Y-coordinates can be programmed from -50% up to +150% to allow clamping in the middle of one
segment (like on the Figure 9), but the output value is limited to CLAMPLOW and CLAMPHIGH values.
Between two consecutive points, the output characteristic is interpolated.
The parameter W determines the input range on which the 17 points (16 segments) are uniformly spread:

15.1.5. CLAMPING Parameters
The clamping levels are two independent values to limit the output voltage range. The CLAMPLOW
parameter adjusts the minimum output voltage level. 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).

Figure 10 - Input range from -40Deg.C up to 160 Deg.C
The thermal offset is added before the clamping (see section 15.1.5). 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).
If the temperature is higher than 35 Deg.C then: output ≤ output – ΔT * ANGLEOFSSLOPEHOT
If the temperature is lower than 35 Deg.C then: output ≤ output – ΔT * ANGLEOFSSLOPECOLD
Where output is the calculated output adjusted by the thermal correction offset ΔT * ANGLEOFSSLOPECOLD.
Where ΔT is the difference between the current temperature and the reference temperature 35Deg.C. The
output correction capability at hot and room (extreme temperature and maximum value of
ANGLEOFSSLOPEHOT and ANGLEOFSSLOPECOLD) are given in the table below.

15.4.2. 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 “GAIN 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.

Diagnostic features which can be enabled by user.
15.7. EEPROM endurance
Although the EEPROM is used for Calibration Data Storage (similarly to an OTPROM), the MLX90367
embedded EEPROM is qualified to guarantee a minimum endurance of 1000 write cycles at 125˚C for
(engineering/calibration purpose).
