Conventional planar Hall technology is only sensitive to the flux density applied orthogonally to the IC surface. The IMC-Hall current sensor is sensitive to the flux density applied parallel to the IC surface. This is obtained through an Integrated Magneto-Concentrator (IMC-Hall) which is deposited on the CMOS die (as an additional back-end step). The IMC-Hall technology is automotive qualified. The product is a single chip Hall sensor which provides an output signal proportional to the flux density applied horizontally and is therefore suitable for current measurement. It is ideally suited as an open loop current sensor for PCB or bus bar mounting. It features small size application design and a simple construction for various current ranges from few Amperes up to 1000 Amperes. The transfer characteristic of the MLX91208 is programmable in terms of offset, gain or temperature compensation. The linear analog output is designed for applications where a very fast response is required, such as inverter applications.

The resolution for the offset and offset drift calibration is better than 0.1%Vdd. Trimming capability is higher than measurement accuracy. End user calibration can increase the accuracy of the system. 3901091208 REV004 Page 8 of 17 Data Sheet September 2015 ® MLX91208 ® IMC-Hall Current Sensor (Triaxis Technology) 9 Programmable items 9.1 Parameter table Parameter Bits Comment VOQ[11:0] 12 Quiescent output level (0 Gauss) adjustment RG[2:0] 3 Rough gain adjustment FG[9:0] 10 Fine gain adjustment ENRATIO 1 Ratiometry enablement TC1[7:0] 8 Adjustment of the first order temperature compensation of the magnetic sensitivity TC2HOT[4:0] 5 Adjustment of the extra temperature compensation of the magnetic sensitivity at high temperature TC2COLD[4:0] 5 Adjustment of the extra temperature compensation of the magnetic sensitivity at low temperature OFFDR2C[5:0] 6 Adjustment of the offset drift at low temperature after the VGA OFFDR2H[5:0] 6 Adjustment of the offset drift at high temperature after the VGA NOISEFILT 1 Noise filter enablement CRC[15:0] 16 16-bit CRC for the checksum calculation of the configuration register. ID[47:0] 48 Customer identification code Table 9: Customer programmable items 9.2 Sensitivity programming (RG, FG) The sensitivity can be programmed from 50 to 300mV/mT (high field version) or 100 to 700mV/mT (low field version), with the ROUGHGAIN (3 bits) and FINEGAIN (10 bits) parameters. 9.3 Offset / output quiescent voltage programming (VOQ) The offset is programmable with 12 bits in 1.5 mV steps over the full output range. This corresponds to a calibration resolution of 0.03 %VDD. The typical step size would be 5V/4096 = 1.22 mV, but the actual step size can differ from the nominal value because of internal gain tolerance. A maximum step size of 1.5 mV is guaranteed. Note: for optimal performance over temperature, the VOQ should be programmed in the range from 2 to 3V. 9.4 Output ratiometry (ENRATIO) The ratiometry of the output versus the supply can be disabled by setting this bit to 0. Note: for optimal performance over temperature, the ratiometry setting should not be changed on customer side. By default, this setting is enabled during final test calibration. 3901091208 REV004 Page 9 of 17 Data Sheet September 2015 MLX91208 ® ® IMC-Hall Current Sensor (Triaxis Technology) 9.5 Sensitivity temperature drift programming (TC1ST, TC2ND_COLD, TC2ND_HOT) First order sensitivity temperature drift can be trimmed with TC1. The programming resolution is 40ppm/K. Second order sensitivity temperature drift can be trimmed with TC2COLD and TC2HOT. The programming resolution is 2ppm/K2 for TC2COLD and 0.6ppm/K2 for TC2HOT.The second order can also be seen as third order correction since cold and hot sides are independently adjusted. Note: for optimal performance over temperature, the first order sensitivity drift compensation (TC1ST) should not exceed ±250ppm/K. 9.6 Offset temperature drift programming (OFFDR2C, OFFDR2H) Offset temperature drift caused by the output amplifier can be compensated with these two parameters. This first order correction is done independently for temperatures over and below 25°C. Note: Two additional parameters (OFFDR1C, OFFDR1H) are calibrated by Melexis to compensate for the offset temperature drift caused by the Hall element (before the variable gain amplifier). These parameters should not be adjusted on customer-side. 9.7 Noise filter (NOISEFILT) Setting this bit to 1 enables the noise filter, reducing noise and increasing response time. 9.8 Identification code (ID) 48 bits programmable identification code. 10 Self diagnostic The MLX91208 provides self diagnostic features to detect internal memory errors and over- / under-voltage. Those features increase the robustness of the IC functionality, as they prevent the IC from providing erroneous output signal in case of internal or external failure modes.

Figure 3: Low current applications with either multi-trace/multi-layer PCB (left) or closed shield (right). 11.2 Medium current measurement up to ±50A For medium currents, a single PCB trace can be used. The sizing of the PCB trace should take into account the current handling capability and the total power dissipation. The PCB trace should be thick and wide enough to handle the RMS current continuously. A simple “U-shaped” ferromagnetic shield is often required to protect the sensor from cross-talk or external stray fields, if they cannot be cancelled-out by other means (peak-peak detection, etc.). Figure 4: Medium current application on PCB 11.3 High current measurement up to ±1000A For high currents flowing in a bus bar, MLX91208 is typically assembled on a PCB lying immediately above the current conductor. A ferromagnetic shield is usually added to protect the sensor from external fields and ensure good homogeneity of the magnetic flux, for optimal robustness against vibrations and mechanical tolerances.
