Byvirtue of fixing the current conductor position withrespect to the monolithic CMOS sensor, a fullyintegrated Hall-effect current sensor is obtained,that is factory calibrated.Inside the package, the magnetic flux densitygenerated by the current flow is senseddifferentially by two sets of Hall plates. As a resultthe influence of external disturbing fields isminimized in the fast analog front-end. Theresidual signal is amplified to provide a high-speedlinear analog output voltage.The close proximity of the Hall plates to the currentconductor ensures a high signal-to-noise ratio andan accurate signal over temperature. Even with thisminiaturization, high voltage isolation ratings arestill maintained between the primary and theopposing secondary side.SOIC-8SOIC-16IEC/UL 62368-1:2014(2nd edition)

MLX91220 Integrated Current Sensor ICDatasheet2. Functional DiagramFigure 1: Functional Diagram for MLX91220The sensor can be used in 2 different modes, depending on the application. Both modes rely on the output voltageof the sensor being proportional to the flow of current, but the difference resides in the signal reconstruction.Ratiometric ModeFigure 2: Schematic of ratiometric modeNo matter if the VDD line is at 5V or deviating /-10%, the ADC code for a given measured current will always be thesame as the ADC is supplied by the same voltage as the sensor. The sensor has a sensitivity expressed in %VDD/A.DOC. 3901091220, REVISION 3.0 - MAY 6, 2022Page 6 of 38
MLX91220 Integrated Current Sensor ICDatasheetDifferential or Fixed Mode (1)Figure 3: Schemaic of fixed modeIn this particular case the ADC does not necessarily share the same supply voltage with the sensor. For this reason,the sensor is calibrated with an absolute sensitivity regardless of the actual supply voltage. The output signal canbe reconstructed by taking the difference between the output and the reference voltage from the IC. The ADC getsthese two signals as inputs for establishing the sensed current accurately, and is not influenced by the supplyvoltage differences between both sensor and microcontroller, if applicable.ParameterRatiometric ModeDifferential or Fixed ModeVOUT [%VDD]VOUT - VREF [V]Example: output is 2.5V when supply is 5V output is then 50%VDD. If the supply (VDD)increases with 5% to 5.25V the sensor outputwill (for the same measured input current)scale proportionally with the supply voltage,becoming 2.625V, but as a percentage (i.e.ratiometrically seen) it remains at 50% of VDD.Example: output is 2.501V andVREF is 2.501V when supply is 5V.When the supply voltage isincreasing to 5.1V due to supplysystem variation, the sensor willstill maintain the same “fixed”output values VOUT and VREF.OffsetVOUT[0A] 50 [%VDD] (factory trimmed)VREF 2.5 [V] (factory trimmed)VOUT[0A]-VREF 0 [V]Offset ty ratiometricYesNoMeasured Current(VOUT-VOUT[0A]) / Sensitivity(VOUT-VREF) / SensitivityOutput SignalTable 3: Parameters of differential and fixed modes(1) More information can be found in Application Note AN91220 ReferencePin on www.melexis.comDOC. 3901091220, REVISION 3.0 - MAY 6, 2022Page 7 of 38

The differential measurement cancels out such common mode magnetic fields, but due to the matchingbetween both Hall plate clusters flanking the current conductor, this is not perfect. This parameter expresses the mAoutput error as a result of such 1 mT applied field. It has to be noted, that ma gnetic fields generated by nearbyconductors are not homogenous but introduce gradients.

To obtain the linearityerror, the current is swept from -𝐼𝑃𝑀 to 𝐼𝑃𝑀 . To decorrelate the thermal drift from the linearity error, thejunction temperature should be fixed below 50 C.𝑁𝐿 𝑉𝑜𝑢𝑡 [𝐼] 𝐵𝐸𝑆𝑇𝐹𝐼𝑇(𝑉𝑜𝑢𝑡 [𝐼]). 100 [%𝐹𝑆]𝑉𝑜𝑢𝑡 [𝐼𝑃𝑀 ] 𝑉𝑜𝑢𝑡 [ 𝐼𝑃𝑀 ]DOC. 3901091220, REVISION 3.0 - MAY 6, 2022Page 15 of 38
