MLX91208 IMC-Hall(R) Current Sensor (Triaxis(R)Technology) 1. Features and Benefits 3. Description Triaxis Technology Very high sensitivity due to Integrated Magnetic Concentrator (IMC-Hall(R)) Programmable high speed current sensor IC Wideband: DC to 250kHz Short response time 3us The MLX91208 is a monolithic sensor IC featuring the Triais Hall technology. 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 MagnetoConcentrator (IMC-Hall) which is deposited on the CMOS die (as an additional back-end step). The IMC-Hall technology is automotive qualified. Programmable linear transfer characteristic Selectable Analog ratiometric output SOIC8 package RoHS compliant Lead free component, suitable for lead free soldering profile 260C (target), MSL3 AEC-Q100 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. 2.

Remarks to the achievable accuracy The achievable target accuracy is dependent on user's end-of-line calibration. The resolution for the offset and offset drift calibration is better than 0.1%Vdd. Trimming capability is higher than the measurement accuracy. End-user calibration can increase the accuracy of the system. 3901091208 Rev.007 Page 9 of 20 MLX91208 June 2018 MLX91208 IMC-Hall(R) Current Sensor (Triaxis(R)Technology) 11.

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. 11.3. Offset / output output quiescent voltage programming (VOQ) 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. 11.4. Output ratiometry (ENRATIO) The ratiometry of the output versus the supply can be disabled by setting this bit to 0. 3901091208 Rev.007 Page 10 of 20 MLX91208 June 2018 MLX91208 IMC-Hall(R) Current Sensor (Triaxis(R)Technology) 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. 11.5. 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. 11.6. Offset temperature drift programming (OFFDR2 (OFFDR2C, OFFDR2 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 25C. 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. 11.7. Noise filter (NOISEFILT) Setting this bit to 1 enables the noise filter, reducing noise and increasing response time. 11.8. Identification code (ID) 48 bits programmed identification code. 3901091208 Rev.007 Page 11 of 20 MLX91208 June 2018 MLX91208 IMC-Hall(R) Current Sensor (Triaxis(R)Technology) 12. 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.

Application information Please refer to our current sensor reference design guide for more application information: http://melexis.com/Assets/Current-Sensors-Reference-Designs-6187.aspx 13.1. Low current measurement 22-10A Low currents can be measured by either using a multi-turn/multi-layer PCB where the current is allowed to flow several times under the sensor, or by adding a closed ferromagnetic shield around the current trace with a small air gap to concentrate the magnetic flux above the sensor. Figure 4: Low current applications with either multi-trace/multi-layer PCB (left) or closed shield (right). 3901091208 Rev.007 Page 12 of 20 MLX91208 June 2018 MLX91208 IMC-Hall(R) Current Sensor (Triaxis(R)Technology) 13.2. Medium current measurement up to 50A 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 5: Medium current application on PCB 13.3. 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. 3901091208 Rev.007 Page 13 of 20 Figure 6: High current application on bus bar MLX91208 June 2018 MLX91208 IMC-Hall(R) Current Sensor (Triaxis(R)Technology) 14.
