Rotary Position Sensor IC
2. Description
The MLX90316 is a monolithic sensor IC featuring the Tria⊗is® Hall technology. Conventional planar Hall
technology is only sensitive to the flux density applied orthogonally to the IC surface. The Tria⊗is® Hall
sensor is also sensitive to the flux density applied parallel to the IC surface. This is obtained through an
Integrated Magneto-Concentrator (IMC) which is deposited on the CMOS die (as an additional back-end
step).
The MLX90316 is only sensitive to the flux density coplanar with the IC surface. This allows the
MLX90316 with the correct magnetic circuit to decode the absolute rotary (angular) position from 0 to 360
Degrees. It enables the design of novel generation of non-contacting rotary position sensors that are
frequently required for both automotive and industrial applications.
In combination with the appropriate signal processing, the magnetic flux density of a small magnet
(diametral magnetization) rotating above the IC can be measured in a non-contacting way (Figure 4). The
angular information is computed from both vectorial components of the flux density (i.e. BX and BY).
MLX90316 produces an output signal proportional to the decoded angle. The output is selectable between
Analog, PWM and Serial Protocol.

6. Detailed Description
As described on the block diagram (Figure 1, Figure 2 and Figure 3), the magnetic flux density parallel to
the IC surface (i.e. B//) is sensed through the Tria⊗is® sensor front-end. This front-end consists into two
orthogonal pairs (for each of the two directions parallel with the IC surface i.e. X and Y) of conventional
planar Hall plates (blue area on Figure 5) and an Integrated Magneto-Concentrator (IMC yellow disk on
Figure 5).

Rotary Position Sensor IC
Both components of the applied flux density B// are measured individually i.e. BX// and BY//. Two orthogonal
components (respectively BX⊥ and BY⊥) proportional to the parallel components (respectively BX// and BY//)
are induced through the IMC and can be measured by both respective pairs of conventional planar Hall
plates as those are sensitive to the flux density applied orthogonally to them and the IC surface.
While a magnet (diametrically magnetized) rotates above the IC as described on Figure 4, the sensing
stage provides two differential signals in quadrature (sine and cosine − Figure 6 and Figure 7)

Rotary Position Sensor IC
Those Hall signals are processed through a fully differential analog chain featuring the classic offset
cancellation technique (Hall plate quadrature spinning and chopper-stabilized amplifier).
The conditioned analog signals are converted through an ADC (configurable − 14 or 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 angular position from the two raw signals (after so-called front-end
compensation steps) through the following operation:
VY
α
= ATAN
VX
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 ″ATAN″ function, the F/W controls the whole
analog chain, the output transfer characteristic, the output protocol, the programming/calibration and also
the self-diagnostic modes.
In the MLX90316, the ″ATAN″ function is computed via a look-up table (i.e. it is not obtained through a
CoRDiC algorithm).
Due to the fact that the ″ATAN″ operation is performed on the ratio ″VY/VX″, the angular information is
intrinsically self-compensated vs. flux density variations (due to airgap change, thermal or ageing effects)
affecting both signals. This feature allows therefore an improved thermal accuracy vs. rotary position
sensor based on conventional linear Hall sensors.
In addition to the improved thermal accuracy, the realized rotary position sensor is capable of measuring a
complete revolution (360 Degrees) and the linearity performances are excellent taking into account typical
manufacturing tolerances (e.g. relative placement between the Hall IC and the magnet).
Once the angular information is computed (over 360 degrees), it is further conditioned (mapped) vs. the
target transfer characteristic and it is provided at the output(s) as:
•
•
•
an analog output level through a 12 bit DAC followed by a buffer
a digital PWM signal with 12 bit depth (programmable frequency 100 Hz … 1 kHz)
a digital Serial Protocol (SP − 14 bits computed angular information available)
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 either a 2 point or a 3 point calibration
depending on the linearity requirement.
A digital output is also available and used as a programmable angular switch.
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 MLX90316 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).

14.1.1. Analog Output Mode
The Analog Output Mode is a rail-to-rail and ratiometric output with a push-pull output stage configuration
allows the use of a pull-up or pull-down resistor.
14.1.2. PWM Output Mode
If one of the PWM Output modes is selected, the output signal is a digital signal with Pulse Width
Modulation (PWM).
In mode 5, the output stage is an open drain NMOS transistor (low side), to be used with a pull-up resistor
to VDD
In mode 7, the output stage is a push-pull stage for which Melexis recommends the use of a pull-up
resistor to VDD
.
.
The PWM polarity is selected by the PWMPOL1 parameter:
•
•
PWMPOL1 = 0 for a low level at 100%
PWMPOL1 = 1 for a high level at 100%

KDHYST
The switch is activated (Sw_lo) when the digital angle is greater than the value stored in the KD
parameter. This angle refers to the internal angular reference linked to the parameter DP and not to the
absolute physical 0°angle.
The KDHYST defines the hysteresis amplitude around the Switch point. The switch is actually activated if
the digital angle is greater than KD+KDHYST. It is deactivated if the digital angle is less than
KD-KDHYST.
The mandatory application diagram to use this feature is depicted in the Figure 9. See section 7 for the
electrical characteristic.
If the Switch feature is not used in the application, the output pin needs to be connected to the ground.

14.2.1. CLOCKWISE Parameter
The CLOCKWISE parameter defines the magnet rotation direction.
•
•
CCW is the defined by the 1-4-5-8 pin order direction for the SOIC8 package and 1-8-9-16 pin
order direction for the TSSOP16 package.
CW is defined by the reverse direction: 8-5-4-1 pin order direction for the SOIC8 and 16-9-8-1 pin
order direction for the TSSOP16 package.
Refer to the drawing in the IMC positioning sections (Section 20.3 and 20.6).
14.2.2. Discontinuity Point (or Zero Degree Point)
The Discontinuity Point defines the 0°point on the circle. The discontinuity point places the origin at any
location of the trigonometric circle. The DP is used as reference for all the angular measurements.

14.2.3. 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 MLX90316 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.

14.2.4. CLAMPING Parameters
The clamping levels are two independent values to limit the output voltage range. The CLAMP_LOW
parameter adjusts the minimum output voltage level. The CLAMP_HIGH parameter sets the maximum
output voltage level. Both parameters have 16 bits of adjustment. 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. In
SPI mode, the resolution is 14bits or 0.022deg over 360deg.

14.2.5. DEADZONE Parameter
The dead zone is defined as the angle window between 0 and 359.9999.
When the digital angle lies in this zone, the IC is in fault mode (RESONFAULT must be set to “1” – See
14.6.1).
14.2.6. MLX90316 xDC- BCS ONLY
The MLX90316 BCS firmware offers the possibility to program a second output transfer characteristic of
the single die version.
The following formula is used in the 90316BxS:
O
UT2 = OUT2SlopeRatio * OUT1 + OUT2Offset
Range OUT2 = [ Clamp_Low OUT2..Clamp_High OUT2 ]
UT2 SLOPE RATIO Controls the slope ratio OUT1 vs OUT2. The ratio can be positive or negative.
O
The example of MLX90316LDC-BCS-PPA is given in the figure below (slope = -1, OUT2 = -1 x slope OUT1

14.4.1. HIGHSPEED Parameter
The HIGHSPEED parameter defines the main frequency for the DSP.
•
•
HIGHSPEED = 0 selects the Slow mode with a 7 MHz master clock.
HIGHSPEED = 1 selects the Fast mode with a 20 MHz master clock.
For better noise performance, the Slow Mode must be enabled.
14.4.2. ARGC, AUTO_RG, RoughGain and FORCECRA75 Parameters
AUTO_RG and ARGC parameters enable the automatic gain control (AGC) of the analog chain. The AGC
loop is based on
(VX)²+ (VY)² = (Amplitude)² = (Radius)²
and it targets an amplitude of 90% of the ADC input span.
At Start-Up phase, the gain stored in the parameter RoughGain is always used. Depending of the
AUTO_RG and ARGC settings, the AGC regulation acts as follow:
•
If ARGC is set, the regulation proceeds by jump to reach the target gain. Note that this regulation
is only valid if the starting gain does not saturate the ADC. Melexis recommendation is to use
RoughGain ≤ 3 if ARGC=1.
•
If ARGC is “0” and AUTO_RG is set to “1”, the regulation adapts every cycle by one gain code the
current gain to reach the 90% ADC span target. Note that if the value of RoughGain is too far
from the actual gain, the chip will enter the normal operating mode (after the Start-Up phase) with
an incorrect gain which will cause the device to go in diagnostic low (field too low/field too high –
See section 15).
•
If ARGC and AUTO_RG are “0”, the AGC regulation is off and the gain used is the value stored in
the parameter RoughGain. Melexis does not advise the use of this mode.
The parameter AUTO_RG activates the automatic regulation during normal operation of the device as
background task.
The parameter FORCECRA75 modifies the target of the AGC algorithm to 75% - instead of 90% - of the
ADC span (at start-up and in normal operation).

Rotary Position Sensor IC
Melexis strongly recommend to set ARGC = “1”, AUTO_RG = “1” and RoughGain ≤ 3 for all types of
application. If the magnetic specifications of the application are well known and under control, the
appropriate RoughGain can also be programmed with ARGC set to “0” and AUTO_RG to “1”.
Please note that the angular errors listed in the section 10 are only valid if the AUTO_RG is activated.
AUTO_RG avoids also the saturation of the analog chain and the associated linearity error.
The current gain (RG) can be read out with the PTC-04 and gives a rough indication of the applied
magnetic flux density (Amplitude).
14.4.3. RGThresL, RGThresH Parameters
RGThresL & RGThresH define the boundaries within the gain setting (Rough Gain) is allowed to vary.
Outside this range, the output is set in diagnostic low.

FSWAP
The MLX90316 includes 3 types of filters:
•
•
•
Hysteresis Filter: programmable by the FHYSTꢁparameter
Low Pass FIR Filters controlled with the Filter parameter
Low Pass IIR Filter controlled with the Filter parameter and the coefficients FILTER A1 and
FILTER A2
Note: if the parameter FSWAP is set to “1”, the filtering is active on the digital angle. If set to “0”, the
filtering is active on the output transfer function.
14.5.1. 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.
Please note that for the programmable version, the FHYST parameter is set to 4 by default. If you do not
wish this feature, please set it to “0”.
14.5.2. FIR Filters
The MLX90316 features 6 FIR filter modes controlled with Filter = 0…5. The transfer function is described

RESONFAULT

14.6.1. RESONFAULT Parameter
This RESONFAULT parameter enables the soft reset when a fault is detected by the CPU when the
parameter is set to 1. By default, the parameter is set to “0” but it is recommended to set it to “1” to
activate the self diagnostic modes (See section 15).
Note that in the User Interface (MLX90316UI), the RESONFAULT is split in two bits:
•
•
DRESONFAULT: disable the reset in case of a fault.
DOUTINFAULT: disable output in diagnostic low in case of fault.
14.6.2. EEHAMHOLE Parameter
The EEHAMHOLE parameter disables the CRC check and the memory recovery (Hamming code) when it
is equal to 3131h. Melexis strongly recommends to set the parameter to 0 (enable memory recovery).
This is done automatically when using the MEMLOCK function.

15. MLX90316 Self Diagnostic
The MLX90316 provides numerous self-diagnostic features. Those features increase the robustness of the IC
functionality as it will prevent the IC to provide erroneous output signal in case of internal or external failure
modes (“fail-safe”).

Rotary Position Sensor IC
16. Serial Protocol
16.1. Introduction
The MLX90316 features a digital Serial Protocol mode. The MLX90316 is considered as a Slave node.
The serial protocol of the MLX90316 is a three wires protocol (/SS, SCLK, MOSI-MISO):
•
•
•
/SS pin is a 5 V tolerant digital input
SCLK pin is a 5 V tolerant digital input
MOSI-MISO pin is a 5 V tolerant open drain digital input/output
The basic knowledge of the standard SPI specification is required for the good understanding of the
present section.
16.2. SERIAL PROTOCOL Mode
•
•
CPHA = 1 ꢂ even clock changes are used to sample the data
CPOL = 0 ꢂ active-Hi clock
The positive going edge shifts a bit to the Slave’s output stage and the negative going edge samples the
bit at the Master’s input stage.
16.3. MOSI (Master Out Slave In)
The Master sends a command to the Slave to get the angle information.
16.4. MISO (Master In Slave Out)
The MISO of the slave is an open-collector stage. Due to the capacitive load (TBD) a >1 kΩ pull-up is
used for the recessive high level (in fast mode). Note that MOSI and MISO use the same physical pin of
the MLX90316.
16.5. /SS (Slave Select)
The /SS pin enables a frame transfer (if CPHA = 1). It allows a re-synchronization between Slave and
Master in case of communication error.
16.6. Master Start-Up
/SS, SCLK, MISO can be undefined during the Master start-up as long as the Slave is re-synchronized
before the first frame transfer.
16.7. Slave Start-Up
The slave start-up (after power-up or an internal failure) takes 16 ms. Within this time /SS and SCLK is
ignored by the Slave. The first frame can therefore be sent after 16 ms. MISO is Hi-Z (i.e. Hi-Impedance)
until the Slave is selected by its /SS input. MLX90316 will cope with any signal from the Master while
starting up.

MLX90316
Rotary Position Sensor IC
16.8. Timing
To synchronize communication, the Master deactivates /SS high for at least t5 (1.5 ms). In this case, the
Slave will be ready to receive a new frame. The Master can re-synchronize at any time, even in the middle
of a byte transfer.
Note: Any time shorter than t5 leads to an undefined frame state, because the Slave may or may not
have seen /SS inactive.

16.9. Slave Reset
On internal soft failures the Slave resets after 1 second or after an (error) frame is sent. On internal hard
failures the Slave resets itself. In that case, the Serial Protocol will not come up. The serial protocol link is
enabled only after the completion of the first synchronization (the Master deactivates /SS for at least t5).
16.10. Frame Layer
ꢀ
16.10.1. Command Device Mechanism
Before each transmission of a data frame, the Master should send a byte AAh to enable a frame transfer.
The latch point for the angle measurement is at the last clock before the first data frame byte.

16.10.2. Data Frame Structure
A data frame consists of 10 bytes:
•
•
•
•
2 start bytes (AAh followed by FFh)
2 data bytes (DATA16 – most significant byte first)
2 inverted data bytes (/DATA16 - most significant byte first)
4 all-Hi bytes
The Master should send AAh (55h in case of inverting transistor) followed by 9 bytes FFh. The Slave will
answer with two bytes FFh followed by 4 data bytes and 4 bytes FFh.
16.10.3. Timing
There are no timing limits for frames: a frame transmission could be initiated at any time. There is no inter-
frame time defined.

16.10.5. Angle Calculation
All communication timing is independent (asynchronous) of the angle data processing. The angle is
calculated continuously by the Slave:
•
•
Slow Mode: every 1.5 ms at most.
Fast Mode: every 350 s at most.
ꢀ
The last angle calculated is hold to be read by the Master at any time. Only valid angles are transferred by
the Slave, because any internal failure of the Slave will lead to a soft reset.
16.10.6. Error Handling
In case of any errors listed in section 16.10.4, the Serial protocol will be initialized and the error condition
can be read by the master. The slave will perform a soft reset once the error frame is sent.
In case of any other errors (ROM CRC error, EEPROM CRC error, RAM check error, intelligent watchdog
error…) the Slave’s serial protocol is not initialized. The MOSI/MISO pin will stay Hi-impedant (no error
frames are sent).
