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. B

X

and B

Y

).

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).

Hall Plates

Both components of the applied flux density B

//

are measured individually i.e. B

X//

and B

Y//

. Two orthogonal

components (respectively B

X⊥

and B

Y⊥

) proportional to the parallel components (respectively B

X//

and B

Y//

)

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)

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:













=

X

Y

V

ATAN

α

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 ″V

Y

/V

X

″, 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 for α ≤ αmin

Vout(α) = Voffset + Gain × α for αmin ≤ α ≤ αmax

Vout(α) = ClampHi 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).

The Intrinsic Linearity Error refers to the IC itself (offset, sensitivity mismatch, orthogonality) taking into account an ideal

rotating field. 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 that is available on the

MLX90316.

14. Description of End-User Programmable Items

14.1. Output Mode

The MLX90316 output type is defined by the Output Mode parameter.

Parameter Value Description

Analog Output Mode 2, 4 Analog Rail-to-Rail

PWM Output Mode 5

7

Low Side (NMOS)

Push-Pull

Serial N/A Low Side (NMOS)

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 V

DD

.

In mode 7, the output stage is a push-pull stage for which Melexis recommends the use of a pull-up

resistor to V

DD

.

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%

MLX90316

Rotary Position Sensor IC

3901090316

Page 18 of 45 Mar/12

Rev08

The PWM frequency is selected by the PWMT parameter.

PWM Frequency Code (based on typical main clock frequency)

Oscillator Mode Pulse-Width Modulation Frequency (Hz)

100 200 500 1000

Low Speed ~35000 ~17500 ~7000 ~3500

High Speed - ~50000 ~20000 ~10000

For instance, in Low Speed Mode, set PWMT=7000 (decimal) to set the PWM frequency around

500Hz

(21)

.

14.1.3. Serial Protocol Output Mode

The MLX90316 features a digital Serial Protocol mode. The MLX90316 is considered as a Slave node.

See the dedicated Serial Protocol section for a full description (Section 16).

14.1.4. Switch Out

Parameter Value Unit

KD 0…359.9999 deg

KDHYST 0 … 1.4 deg

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.

Figure 9 – Application Diagram for the Switch Out

21

In order to compensate the lot to lot variation of the main clock frequency (Ck), Melexis strongly recommends trimming the

PWM frequency during EOL programming (see the PTC-04 documentation).

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.

Figure 10 - Discontinuity Point Positioning

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%V

DD

. In PWM mode, the resolution will be 0.024%

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

HIGHSPEED 0 = Slow mode

ARGC 0 = disable

AUTO_RG 0 = disable

1 = enable

RoughGain 0 … 15

RGThresL 0 … 15

RGThresH 0 … 15

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

(V

X

)²+ (V

Y

)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).

MLX90316

Rotary Position Sensor IC

3901090316

Page 23 of 45 Mar/12

Rev08

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.

14.5. FILTER

Parameter Value Unit

FHYST 0 … 11 ; step 0.04 deg

FILTER 0… 6

FSWAP 0

1

The MLX90316 includes 3 types of filters:

• Hysteresis Filter: programmable by the FHYST parameter

• 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

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”).

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  even clock changes are used to sample the data

• CPOL = 0  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

3901090316

Page 31 of 45 Mar/12

Rev08

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

µ

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).
