2. Description
The MLX90242 is a CMOS Linear Hall Effect
sensor IC. It possesses active error correction
circuitry which virtually eliminates the offset
errors normally associated with analog Hall
Effect devices.
The ratiometric output voltage is proportional to
the supply voltage. When using the supply
voltage as a reference for an A/D converter,
fluctuations of +10% in supply voltage will not
affect accuracy. For a positive slope, the voltage
at the output will increase as a South magnetic
field is applied to the branded face of the
MLX90242. Conversely, the voltage output will
decrease in the presence of a North magnetic
field. For a negative slope, the voltage at the
output will increase as a North magnetic field is
applied to the branded face of the MLX90242.
Conversely, the voltage output will decrease in
the presence of a South magnetic field.

7. Applications Information
C1 and C2 values can be trimmed to satisfied
EMC requirements according to the environment
(PCB, connectors,...).
The output rise time is affected for large
capacitor C2, depending of the couple R1;C2.
8. Installation Comments
1.) Avoid mechanical stress on leads or
package.
Stress may cause VOQ shift.
A.) Avoid bending leads at the package interface.
B.) Support the leads by clamping, when bending.
C.) Avoid gluing device to another material.
This may cause temperature-related stress.
2.) CMOS products are static sensitive devices,
please observe ESD precautions.
3.) Observe temperature limits during soldering
Recommended Wiring
C1 = 10nF
C2 = 2.5nF

9. Reliability Information
Melexis devices are classified and qualified regarding suitability for infrared, vapor phase and wave
soldering with usual (63/37 SnPb-) solder (melting point at 183degC).
The following test methods are applied:
IPC/JEDEC J-STD-020A (issue April 1999)
Moisture/Reflow Sensitivity Classification For Nonhermetic Solid State Surface Mount Devices
CECC00802 (issue 1994)
Standard Method For The Specification of Surface Mounting Components (SMDs) of Assessed Quality
MIL 883 Method 2003 / JEDEC-STD-22 Test Method B102
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. For process using through hole components, a temperature profile
of 235 Deg.C during 30 seconds maximum is tolerated.
The application of Wave Soldering for SMD’s is allowed only after consulting Melexis regarding assurance
of adhesive strength between device and board. Please contact MLX for Ua part used as SMD device.
