3-Wire Hall Effect Switch

5 General Description
The Melexis MLX92231 is a Hall-effect unipolar switch designed in mixed signal CMOS technology.
The device integrates a voltage regulator, Hall sensor with advanced offset cancellation system, automotive qualified
EEPROM and an open-drain output driver, all in a single package.
Based on the existing robust 922xx platform, the magnetic core has been equipped with a non-volatile memory that is used to
accurately trim the switching thresholds and define the needed output magnetic characteristics (TC, B OP, BRP, Output pole
functionality).
In addition to that an ID has been integrated on the IC to have a complete traceability throughout the process flow.
The included voltage regulator operates from 2.7 to 24V, hence covering a wide range of applications. With the built-in
reverse voltage protection, a serial resistor or diode on the supply line is not required so that even remote sensors can be
specified for low voltage operation down to 2.7V while being reverse voltage tolerant.
In the event of a drop below the minimum supply voltage during operation, the under-voltage lock-out protection will
automatically freeze the device, preventing the electrical perturbation to affect the magnetic measurement circuitry. The
output state is therefore only updated based on a proper and accurate magnetic measurement result.
The chopper-stabilized amplifier uses switched capacitor techniques to suppress the offset generally observed with Hall
sensors and amplifiers. The CMOS technology makes this advanced technique possible and contributes to smaller chip size
and lower current consumption than bipolar technology. The small chip size is also an important factor to minimize the effect
of physical stress. This combination results in more stable magnetic characteristics and enables faster and more precise
design.
The open drain output is fully protected against short-circuit with a built-in current limit. An additional automatic output shutoff is activated in case of a prolonged short-circuit condition. A self-check is then periodically performed to switch back to
normal operation if the short-circuit condition is released. The on-chip thermal protection also switches off the output if the
junction temperature increases above an abnormally high threshold. It will automatically recover once the temperature
decreases below a safe value.

Typical values are defined at TA = +25°C and VDD = 12V
Guaranteed by design and verified by characterization, not production tested
The Power-On Time represents the time from reaching VDD = 2.7V to the first refresh of the output
Power-On Slew Rate is not critical for the proper device start-up.
Maximum switching frequency corresponds to the maximum frequency of the applied magnetic field which is detected without loss of pulses
RPU and VPU are respectively the external pull-up resistor and pull-up power supply
Activated output with 1 mT overdrive
If the Output is in Current Limitation longer than tCLON the Output is switched off in high-impedance state. The Output returns back in active state at next
reaching of BOP or after tCLOFF time interval

GND
Notes:
1. For proper operation, a 10nF to 100nF bypass capacitor should
be placed as close as possible to the VDD and ground pin.
2. The pull-up resistor RPU value should be chosen in to limit the
current through the output pin below the maximum allowed
continuous current for the device.
3. A capacitor connected to the output is not needed, because the
output slope is generated internally.

Notes:
1. For proper operation, a 10nF to 100nF bypass capacitor should be placed as close as possible to the VDD and ground pin.
2. The device could tolerate negative voltage down to -24V, so if negative transients over supply line VPEAK< -30V are expected, usage of the
diode D1 is recommended. Otherwise only R1 is sufficient.
When selecting the resistor R1, three points are important:
- the resistor has to limit IDD/IDDREV to 50mA maximum
- the resistor has to withstand the power dissipated in both over voltage conditions (VR12/R1)
- the resulting device supply voltage VDD has to be higher than VDD min (VDD = VCC – R1.IDD)
3. The device could tolerate positive supply voltage up to +27V (until the maximum power dissipation is not exceeded), so if positive
transients over supply line with VPEAK> 32V are expected, usage a zener diode Z1 is recommended. The R1-Z1 network should be sized to
limit the voltage over the device below the maximum allowed.

12 Standard information regarding manufacturability of Melexis products
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: http://www.melexis.com/quality.aspx
13 ESD Precautions
Electronic semiconductor products are sensitive to Electro Static Discharge (ESD).
Always observe Electro Static Discharge control procedures whenever handling semiconductor products.
