2. Description
The MLX90365 is a monolithic sensor IC sensitive to the flux density applied orthogonally and parallel to
the IC surface.
The MLX90365 is sensitive to the three components of the flux density applied to the IC (i.e. BX, BY and
BZ). This allows the MLX90365 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 - Figure 2). It
enables the design of novel generation of non-contacting position sensors that are frequently required for
both automotive and industrial applications.
MLX90365 reports a programmable ratiometric analog output signal compatible with any resistive
potentiometer or programmable linear Hall sensor. Through programming, the MLX90365 provides also a
digital PWM (Pulse Width Modulation) output characteristic.

6. Description
As described on the block diagram the three vector components of the magnetic flux density (BX, BY and
BZ) applied to the IC are sensed through the sensor front-end. The respective Hall signals (VX, VY and VZ)
are generated at the Hall plates and amplified.
The analog signal processing is based on a fully differential analog chain featuring the classic offset
cancellation technique (Hall plate 2-Phases spinning and chopper-stabilized amplifier).
The conditioned analog signals are converted through an ADC (15 bits) and provided to a DSP block for
further processing. The DSP stage is based on a 16 bit RISC micro-controller whose primary function is
the extraction of the position from two (out of three) raw signals (after so-called front-end compensation
steps) through the following function:
α = ∠(V1 , k ⋅ V2 )
where alpha is the magnetic angle ∠(B1, B2), V1 = VX or VY or VZ , V2 = VX or VY or VZ and k is a
programmable factor to match the amplitude of V1 and k V2.
The DSP functionality is governed by the micro-code (firmware − F/W) of the micro-controller which is
stored into the ROM (mask programmable). In addition to the magnetic angle extraction, the F/W controls
the whole analog chain, the output transfer characteristic, the output protocol, the programming/calibration
and also the self-diagnostic modes.
The magnetic angular information is intrinsically self-compensated vs. flux density variations. This feature
allows therefore an improved thermal accuracy vs position sensor based on conventional linear Hall
sensors.
In addition to the improved thermal accuracy, the realized position sensor features excellent linearity
performances taking into account typical manufacturing tolerances (e.g. relative placement between the
Hall IC and the magnet).

Triaxis® Position Sensor IC
Once the position (angular or linear stroke) information is computed, it is further conditioned (mapped) vs.
the target transfer characteristic and it is provided at the output(s) as either a ratiometric analog output
level through a 12 bit DAC followed by a buffer or a digital PWM output.
For instance, the analog output can be programmed for offset, gain and clamping to meet any rotary
position sensor output transfer characteristic:
Vout(α) = ClampLo
Vout(α) = Voffset + Gain × α
Vout(α) = ClampHi
for α ≤ αmin
for αmin ≤ α ≤ αmax
for α ≥ αmax
where Voffset, Gain, ClampLo and ClampHi are the main adjustable parameters for the end-user.
The linear part of the transfer curve can be adjusted through a multi-point calibration:
This back-end step consists into either
•
up to 4 arbitrary points (5 segments + clamping levels) calibration or
•
a Piece-Wise-Linear (PWL) output transfer characteristics - 17 equidistant points w/
programmable origin over 16 different angle ranges from 65 to 360 degrees.
The calibration parameters are stored in EEPROM featuring a Hamming Error Correction Coding (ECC).
The programming steps do not require any dedicated pins. The operation is done using the supply and
output nodes of the IC. The programming of the MLX90365 is handled at both engineering lab and
production line levels by the Melexis Programming Unit PTC-04 with the dedicated MLX90316
daughterboard and software tools (DLL − User Interface).

± 0.15 Deg. angular error for the computed angular information (output of the DSP).
13 The Intrinsic Linearity Error refers to the IC itself (offset, sensitivity mismatch, orthogonality) taking into account an ideal
rotating field for BX and BY. Once associated to a practical magnetic construction and the associated mechanical and magnetic
tolerances, the output linearity error increases. However, it can be improved with the multi-point end-user calibration.
14 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 14.6).

14.2.3. Discontinuity Point (or Zero Degree Point)

14.2.4. 4-Pts LNR Parameters
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 MLX90365 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 six calibration points are then available, reducing the overall non-linearity of the IC by
almost an order of magnitude each time. Three to six calibration points 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.

14.2.5. 17-Pts LNR Parameters
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 MLX90365 transfer function from the digital angle value to the output voltage is
described by the drawing below. In the 16-Pts mode, the output transfer characteristic is Piece-WiseLinear (PWL).
Figure 10 - Input range from 65.5° up to 360°
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), 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:

14.2.6. 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.
In analog mode, the resolution will be limited by the D/A converter (12 bits) to 0.024%VDD. In PWM mode,
the resolution will be 0.024%DC.

14.5.2. 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, 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 B1or B2 (according to parameter SEL_k – 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) SEL_k
When the mapping (B1=X, B2=Y) is NOT selected, SEL_k defines the component on which the sensitivity
mismatch factor k (see above): SEL_k = 0 means B1→ k ⋅ B1 and SEL_k = 1 means B2 → k ⋅ B2.
14.5.3. 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 Diag. check.

Triaxis® Position Sensor IC
14.6.1. Hysteresis Filter
The FHYST parameter is a hysteresis filter. The output value of the IC is not updated when the digital step
is smaller than the programmed FHYST parameter value. The output value is modified when the
increment is bigger than the hysteresis. The hysteresis filter reduces therefore the resolution to a level
compatible with the internal noise of the IC. The hysteresis must be programmed to a value close to the
noise level. ( 1 lsb = +/- 0.012%)
14.6.2. FIR Filters
The MLX90365 features 2 FIR filter modes controlled with Filter = 1…2. Filter = 0 corresponds to no
filtering. The transfer function is described below:

In PWM mode, the fault reporting level shall in principle be 0 when the leading edge is a rising edge,
(resp. 1 for a falling edge) in order to detect the first cycle after start-up. MLX recommends then
DIAG Level = PWMPOL.

14.7.3. Field Strength Diagnostic
(i) FIELDTHRESHLOW
Defines the field strength limit under which a fault is reported.
8
The run-time field strength estimation (FieldStrength) is compared to 2 * FIELDTHRESHLOW.
The sensitivity of FIELDTHRESHLOW is typically 1mT/LSB. By default it is programmed to 10mT
(ii) FIELDTHRESHHIGH
Defines the field strength limit under which a fault is reported. See above for more details.
14.7.4. PWM Diagnostic
(i) DC_FAULT
Defines the duty-cycle that is outputted in case of diagnostic reporting.
(ii) WEAKMAGTHRESH
Defines the threshold on the field strength which determines the weak magnet condition; when
WEAKMAGTHRESH = 0, there is no reporting of weak magnet condition.
(iii) DC_FTL
Defines the duty-cycle that is outputted in case of Field Too Low; the Field Too Low Diagnostic is stronger
than the Weak Magnet Diagnostic, from 0% till 255% by steps of (100/256)%
(iv) DC_WEAK
Defines the duty-cycle that is outputted in case of Weak Magnet, from 0% till 255% by steps of
(100/256)%
14.7.5. Diagnostic Features
It is recommended to enable the diagnostic features for safety critical applications.
Refer to Application_note_Diagnostic_Behavior_90365 for EE_CRC_Enable function description and for
Diagnostic features which can be enabled by user.
14.8. EEPROM endurance
Although the EEPROM is used for Calibration Data Storage (similarly to an OTPROM), the MLX90365
embedded EEPROM is qualified to guarantee an endurance of minimum 1000 write cycles at 125˚C for
(engineering/calibration purpose).
