2 General Description
The MLX91206 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
Magneto-Concentrator (IMC-Hall®) which is deposited on the CMOS die (as an additional back-end step).
The IMC-Hall® current sensor is automotive qualified.
The product is a single chip Hall sensor which provides an output signal which is proportional to the flux
density applied horizontally and is therefore suitable for current measurement. It is ideally used as an open
loop current sensor for PCB mounting. (see figure 2). It features small size application design and a simple
construction for various current ranges.
The transfer characteristic of the MLX91206 is programmable (offset, gain, clamping levels, diagnostic
functions…). The output is selectable between analog and PWM. The linear analog output is used for
application where a very fast response (<10 sec) is required, whereas the PWM output is used for
application where low speed but high output signal robustness is required.

8.3 Remarks to the achievable accuracy
The achievable target accuracy is dependent on users 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.

Please note that the factory calibration is done with PLATEPOL=0 . Melexis cannot guarantee the magnetic

11.7 Sensitivity programming (ROUGHGAIN, FINEGAIN)
The sensitivity is programmable with 3 bits for ROUGHGAIN and 10 bits for FINEGAIN in analog output
application from 60 to 330 V/T (91206-High-Field version) and from 200 to 700 V/T (Low-Field version).
The FINEGAIN resolution depends on the programmed ROUGHGAIN setting. It typically ranges from
0.25V/T (ROUGHGAIN=7) up to 0.01V/T (ROUGHGAIN=0).

In order to have a safety margin regarding mechanical tolerances Melexis recommends designing the
application in such a way that the typical sensitivity can be used with. If the target sensitivity of the module is
out of the defined range (see table above), the hardware and software tools provided by Melexis will not be
able to properly calibrate the sensor.

recommends using the version with the smallest gain to optimize the performances.

11.11 Power limitation / PWM rise and fall time (OUTSLOPE)
OUTSLOPE, in the analog mode case, defines the power limit above which the output driver turns off to
prevent damages to the IC.
The power dissipated in the IC output driver is measured by the IC itself. The power is obtained by multiplying
continuously the voltage across the conducting MOS driver by the output current Iout. When the power
reaches the power limit, the output driver is switched off and on such that, on average, the measured power
is maintained equal to the power limit. The power limitation is disabled when OUTSLOPE=3.

11.14 Sensitivity and temperature drift programming (TC1ST, TC2ND_COLD,
TC2ND_HOT)
First order sensitivity temperature drift can be trimmed from -2000 to 2000 ppm/degC with TC1ST. The
programming resolution is 40 ppm/degC.
Second order sensitivity temperature drift can be trimmed from -6 to 6 ppm/degC2 with TC2ND. The
programming resolution is 0.4/ppm/degC2.The second order can also be seen as third order correction since
cold and hot sides are independently adjusted.
11.15 Offset temperature drift programming (OFFDRIFT_COLD, OFFDRIFT_HOT)
Offset temperature drift can be trimmed from -2.25 to +2.25 mV/degC. The programming resolution is 0.075
mV/degC. This first order correction is done independently for temperatures over 25degC and below 25degC.

12 Application information
12.1 Low current measurement up to ±2 A
Low currents can be measured with the MLX91206 by
increasing the magnetic field via a coil around the sensor.
The sensitivity (output voltage vs. current in coil) of the
measurement will depend on the size of coil and number
of turns. Additional sensitivity and increased immunity to
external fields can be gained by adding a shield around
the coil. The bobbin provides very high dielectric isolation
making this a suitable solution for high voltage power
supplies with relative low currents. The output should be
scaled to obtain the maximum voltage for the highest
current to be measured in order to obtain the best
accuracy and resolution.
Figure 3: Low current application
12.2 Medium current up to ±30 A
With a single conductor located on the PCB, currents in the
range of up to 30 amps can be measured. The sizing of the
PCB trace needs to take into account the current handling
capability and the total power dissipation. The PCB trace
needs to be thick enough and wide enough to handle the
RMS current continuously.
The differential output voltage for this configuration can be
approximated by the following equation:
Vout = 35 mV/A * I
For a current level of 30 A, the output will be approximately
1050 mV.
Figure 4: Medium current application
12.3 High current measurement up to ±600 A
Another method of measuring high currents on PCB’s is to use
a large thick gauge copper trace capable of carrying the
current on the opposite side of the PCB. The MLX91206
should be located near the centre of the trace, however
because the trace is wide, the output is less sensitive to
location on the PCB. This configuration also has less
sensitivity due to the distance and width of the conductor.

14 Standard information regarding manufacturability of Melexis
products with different soldering processes
Our products are classified and qualified regarding soldering technology, solderability and moisture sensitivity
level according to following test methods:
Reflow Soldering SMD’s (Surface Mount Devices)
IPC/JEDEC J-STD-020
Moisture/Reflow Sensitivity Classification for Nonhermetic Solid State Surface Mount Devices
(classification reflow profiles according to table 5-2)
EIA/JEDEC JESD22-A113
Preconditioning of Nonhermetic Surface Mount Devices Prior to Reliability Testing
(reflow profiles according to table 2)
Wave Soldering SMD’s (Surface Mount Devices) and THD’s (Through Hole Devices)
EN60749-20
Resistance of plastic- encapsulated SMD’s to combined effect of moisture and soldering heat
EIA/JEDEC JESD22-B106 and EN60749-15
Resistance to soldering temperature for through-hole mounted devices
Iron Soldering THD’s (Through Hole Devices)
EN60749-15
Resistance to soldering temperature for through-hole mounted devices
Solderability SMD’s (Surface Mount Devices) and THD’s (Through Hole Devices)
EIA/JEDEC JESD22-B102 and EN60749-21
Solderability
For all soldering technologies deviating from above mentioned standard conditions (regarding peak
temperature, temperature gradient, temperature profile etc) additional classification and qualification tests
have to be agreed upon with Melexis.
The application of Wave Soldering for SMD’s is allowed only after consulting Melexis regarding assurance of
adhesive strength between device and board.
Melexis is contributing to global environmental conservation by promoting lead free solutions. For more
information on qualifications of RoHS compliant products (RoHS = European directive on the Restriction Of
the use of certain Hazardous Substances) please visit the quality page on our website:
