1. Functional Diagram
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.
3. Glossary of Terms
- Gauss, Tesla: Two units to quantify a magnetic flux density. Conversion: 1 mT = 10 Gauss
- Voq: Quiescent output voltage. Output voltage for B = 0mT.

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 and C2.

8. Standard Information
Our products are classified and qualified regarding soldering technology, solderability and moisture sensitivity level
according to standards in place in Semiconductor industry.
For further details about test method references and for compliance verification of selected soldering me thod for
product integration, Melexis recommends reviewing on our web site the General Guidelines soldering
recommendation. For all soldering technologies deviating from the one mentioned in above document (regarding peak
temperature, temperature gradient, temperature profile etc), additional classification and qualification tests have to
be agreed upon with Melexis.
For package technology embedding trim and form post-delivery capability, Melexis recommends to consult the
dedicated trim&form recommendation application note: lead trimming and forming recommendations
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: http://www.melexis.com/en/quality-environment
9. ESD Precautions
