first Hall plate signal is used to provide the speed signal
output. The combination of both the first and second Hall

2. General Description
The direction (DIR) output is latched in Low or High state
depending on the movement direction of the applied
magnetic field, as a result of certain magnetic pulse
sequence on both Hall sensors.
The Melexis MLX92251 is a second generation Hall-effect
dual latch designed in mixed signal CMOS technology. The
device integrates a voltage regulator, two Hall sensors with
advanced offset cancellation system and two open-drain
output drivers, all in a single package.
The MLX92251 is delivered in a Green compliant 5-pin Thin
Small Outline Transistor (TSOT) for surface-mount process.
Two Hall plates are integrated on the same piece of silicon,
thus using the high precision of the wafer fabrication
process to ensure a fixed

10. 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

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 recommends reviewing on our web site the General Guidelines soldering recommendation
(http://www.melexis.com/Quality_soldering.aspx) as well as trim&form recommendations
(http://www.melexis.com/Assets/Trim-and-form-recommendations-5565.aspx).
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/quality.aspx
11. ESD Precautions
Electronic semiconductor products are sensitive to Electro Static Discharge (ESD).
Always observe Electro Static Discharge control procedures whenever handling semiconductor products.
