General Description The MLX90328 covers the most typical resistive type of Wheatstone bridge applications for use in an automotive environment. It is a mixed signal sensor interface IC that converts small changes in resistors, configured in a full Wheatstone bridge on a sensing element, to large output voltage variations. The signal conditioning includes gain adjustment, offset control as well as temperature compensation in order to accommodate variations of the different resistive sensing elements. Compensation values are stored in EEPROM and can be reprogrammed with a Melexis tool including the necessary software. The MLX90328 is programmed with a single wire serial interface through the output pin. REVISION 006 – 22 DECEMBER 2017 3901090328 Page 1 of 16 MLX90328 Automotive Sensor Interface Contents 1.

A maximum performance can be obtained with this sensor sensitivity range. A programmable gain with 5 bits from a gain of 9 to 237 is used in the analog front end circuitry to adapt the sensor range to the on chip ADC input range. Half of the ADC input range (= 1.75V) is foreseen to be used during the sensor calibration at the first temperature. The rest of the ADC input range is left for the compensation of the sensor temperature effects. A coarse offset compensation is available to calibrate large sensor offsets. A more detailed overview of the gains in the analog frontend can be found in Table 6. 2 REVISION 006 – 22 DECEMBER 2017 3901090328 Page 4 of 16 MLX90328 Automotive Sensor Interface Parameter Output noise using highest analog gain and lowest filter settings Overall accuracy Symbol Diagnostic limits Diag low Analog saturation output level Min Typ(1) Max 1.4 Units mVrms 0.2 0.4 %FSO 3 %VDD Worst case noise configuration (PFLT=0, SSF=0, G0=30000d, CG=31) Diag high Clamping levels Remarks Clamp low Clamp high Vsat high Taking into account the drifts over temperature and over life, worst case using typical and maximum gain settings Pull up ≥ 4.7kOhm or Pull down ≥ 4.7kOhm Pull down ≥ 8kOhm or Pull up ≥ 4.7kOhm Programmable range with 7 bit resolution for the low clamping level, 9 bit for the high PD ≥ 4.7kOhm PD ≥ 10k or PU ≥ 4.7k Vsat low 96 %VDD 0 50 12.5 100 %VDD %VDD 96 97 0 100 100 3 %VDD %VDD Table 4: General electrical parameters REVISION 006 – 22 DECEMBER 2017 3901090328 Page 5 of 16 MLX90328 Automotive Sensor Interface 10.

The second filter is a first order low pass filter for the pressure signal which has a programmable depth. 10.1. PFLT PFLT is a programmable first order low pass filter. The depth of this filter can be selected. This filter can be configured to select the optimal trade-off between response time and output noise. The low pass filter is implemented according to the following formula: ( ) ( ) ( ) ( ) The PFLT parameter in the formula is set in EEPROM and can have a value between 0 and 9. An overview of typical response times when applying a step on the input using different PFLT filter settings can be found in Table 5. Filter setting 0 disables the PFLT.

SSF The SSF (Small Signal Filter) is a digital filter which is designed not to have an impact on the response time of a fast changing pressure signal like a pressure step. When a large signal change at the input is present, the filter is bypassed and not filtering the signal. For small signal changes, which are in most cases noise, the filter is used and filtering the pressure signal. The Small Signal Filter can be enabled or disabled in EEPROM. 3 Time needed for the output to change from an input pressure step to 90% of its final value.

Analog Front End The analog front end of the MLX90328 consists of a chopping stage and 3 amplification stages as can be seen in Figure 2. There are also several input diagnostics integrated into this front end to be able to detect a broken InP or InN connection or an input which is out of range. This diagnostic information is transferred to the microcontroller to handle further action for example flagging a diagnostic message. G = 4.5 to 10.5 3 bits G = 1.25 or 3.5 CSOF: 1/3 to 2/3 of VDDA G = 1.6, 3.2 or 6.4 InP Input Diag nostics InN OPA Chopping 1us/phase Stage 1: Instrumentation amplifier OPA Stage 2: Differential amplifier Stage 3: Integrator Figure 2: Analog front end block diagram The first stage is an instrumentation amplifier of which the gain can be programmed using 3 bits to cover a gain range between 4.5 and 10.6. Transfer equation: OUTP1 – OUTN1 = Gst1*(InP – InN) in phase 1 OUTP1 – OUTN1 = Gst1*(InN – InP) in phase 2 The second stage is a fully differential amplifier. The gain of the amplifier can be calibrated using 1 bit. Transfer equation: OUTP2 – OUTN2 = -Gst2*(OUTP1 – OUTN1) – Gst2*(CSOF1 – CSOF2) in phase 1 OUTP2 – OUTN2 = -Gst2*(OUTN1 – OUTP1) – Gst2*(CSOF2 – CSOF1) in phase 2 The CSOF1 and CSOF2 signals are generated by the coarse offset DAC with the following transfer functions: VDDA  2 1  VDDA CO[6 : 0] CO7   1 *    * * 2 2 127  3 3 VDDA 1  VDDA CO[6 : 0] CO7  2 CSOF 2    1 *    * * 2 2 127  3 3 CSOF1  CO[6:0] fixes the DAC output. CO7 is used for the polarity. The third stage is an integrator which is controlled using 2 bits to set a gain between 1.6 and 6.4 Transfer equation at the outputs of the amplifier: OUTP3 – OUTN3 = -N*(C1/C2)*(OUTP2 – OUTN2) OUTP3_common_mode and OUTN3_common_mode = VCM = VDDA/2 In this equation N represents the number of integration cycles which is a fixed value of N = 40. C2 is a fixed feedback capacitor of approximately 5pF. C1 can have 3 different values: 0.2pF, 0.4pF or 0.8pF.

It contains besides the processor also ROM, RAM and EEPROM and a set of user and system IO registers. Temperature compensation of the pressure signal and pressure linearization is handled by the microcontroller. For the pressure compensation there are EEPROM parameters allocated to be able to cover a large variety of calibration approaches. Both for gain and offset of the pressure signal, there is a separate temperature dependency programmable ranging from a temperature independence to a first order, second order and finally a third order compensation. This is reflected in EEPROM parameters for the offset (O0, O1, O2 and O3) and for the gain (G0, G1, G2 and G3). If required, the linearity of the pressure signal can also be compensated without a temperature dependency or with a first order temperature dependency through EEPROM parameters L0 and L1. For the temperature compensation of the pressure signal both the internal on-chip temperature as the temperature measured using the sensor bridge resistance can be used. The selection between both can be set in EEPROM using the ‘Tpress Select’ parameter. When using the bridge resistance temperature measurement, a REVISION 006 – 22 DECEMBER 2017 3901090328 Page 9 of 16 MLX90328 Automotive Sensor Interface selection of a 2K, 4K, 8K or a 32K bridge resistance can be done using EEPROM parameter ‘BRIDGE_SEL’(4), see Table 8.

Unique Features Thanks to its state of the art mixed signal chain, the MLX90328 offers the possibility to calibrate several types of resistive Wheatstone bridge technologies allowing the MLX90328 users to reach an outstanding overall sensor accuracy. The MLX90328 is robust for harsh automotive environments like large temperature range, overvoltage conditions and external EMC disturbances. The MLX90328 allows the compensation of sensor nonlinear variations over temperature as well as compensates for the sensor pressure signal non linearity. Several parameters can be programmed through the application pins in the MLX90328 to set clamping levels or filter settings to choose for the best trade-off between signal chain noise and speed. The MLX90328 can also diagnose several error conditions like sensor connections errors. The sensor bias Vbrg which is supplying the external pressure sensor is generated using a regulator. The target sensor supply is 6/7VDDA or typically 3V. The current through the bridge resistance is mirrored and divided so that it can be fed to an IV convertor. The division ratio is depending on the EEPROM selection bit IVSEL which chooses a different ratio for a 2K, 4K, 8K or a 32K sensor bridge. This IV converted signal is a measure for the external temperature so that it can be used for the calibration of the pressure sensor. A short circuit protection is foreseen on the pin Vbrg.

Application Information The MLX90328 only needs 2 capacitors in the application. A 100nF decoupling capacitor connected between the supply line and the ground a 100nF load between the analog output pin and the ground. MLX90328 has built in EMC protection for the sensor supply and sensing element input pins. Therefore it is advised not to place any external capacitors between the sensing element and the interface. Capacitors on the sensor supply or the inputs can even disturb the normal operation of the interface. These recommendations for external components are however only providing a basic protection. Depending on the module design and the EMC requirements different configurations can be needed.
