The device integrates a voltage regulator, Hall sensor with advanced offset cancellation system and an open-drain output driver, all in a single package.Based on a brand new platform, the magnetic core is using an improved offset cancellation system allowing faster and more accurate processing while being temperature insensitive and stress independent. In addition is implemented a negative temperature coefficient of -1100ppm/degC to compensate the natural behaviour of magnets becoming weaker with rise in temperature. 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 voltageduring 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 open drain output is fully protected against short-circuit with a built-in current limit. An additional automatic output shut-off 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. With latching magnetic characteristics, the output is turned low or high respectively with a sufficiently strong South or North pole facing the package top side. When removing the magnetic field, the device keeps its previous state.The MLX92211 is delivered in a Green compliant 3-pin Thin Small Outline Transistor (TSOT) for surface-mount process.Table of Contents1 Functional Diagram (1)2 General Description (1)3 Glossary of Terms (3)4 Absolute Maximum Ratings (3)5 General Electrical Specifications (4)6 Magnetic Specifications (5)7 Output Behaviour versus Magnetic Pole (5)8 Performance Graphs (6)8.1 Magnetic parameters vs. T A (6)8.2 Magnetic parameters vs. V DD (6)8.3 V DSon vs. T A (6)8.4 V DSon vs. V DD (6)8.5 I DD vs. T A (6)8.6 I DD vs. V DD (6)8.7 I LEAK vs. T A (7)8.8 I LEAK vs. V DD (7)8.9 Power Derating vs. T A (7)9 Application Information (8)9.1 Typical Three-Wire Application Circuit (8)9.2 Automotive and Harsh, Noisy Environments Three-Wire Circuit (8)10 Standard information regarding manufacturability of Melexis products with different soldering processes (9)11 ESD Precautions (9)12 Package Information (10)12.1 SE Package (TSOT-3L) (10)12.2 Pin Definitions and Descriptions (10)13 Disclaimer (11)3Glossary of TermsMilliTesla (mT), Gauss Units of magnetic flux density: 1mT = 10 GaussRoHS Restriction of Hazardous SubstancesTSOT Thin Small Outline Transistor (TSOT package) –also referred with the Melexis packagecode “SE”ESD Electro-Static Discharge4Absolute Maximum Ratingsfor extended periods may affect device reliability.1 The maximum junction temperature should not beexceeded2 For maximum 1 hour3 Including current through protection device4 For maximum 1s5 Through protection device6 For VOUT ≤27V.7 For 1000 hours.8 Human Model according AEC-Q100-002 standard9 Machine Model according AEC-Q100-003 standard10 Charged Device Model according AEC-Q100-011 standard mA C C C5 General Electrical Specifications1 Typical values are defined at T A = +25oC and V DD = 12V, unless otherwise specified 2Guaranteed by design and verified by characterization, not production tested 3R PU and V PU are respectively the external pull-up resistor and pull-up power supply 4If the Output is in Current Limitation longer than t CLON the Output is switched off in high-impedance state.

For proper operation, a 10nF to 100nF bypass capacitor should be placed as close as possible to the V DD and ground pin.2. The pull-up resistor R PU 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.9.2Automotive and Harsh, Noisy Environments Three-WireCircuitV OUTNotes:1. For proper operation, a 10nF to 100nF bypass capacitor should be placed as close as possible to the V DD and ground pin.2. The device could tolerate negative voltage down to -27V, so if negative transients over supply line V PEAK< -32V 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 I DD/I DDREV to 50mA maximum - the resistor has to withstand the power dissipated in both over voltage conditions (V R12/R1)- the resulting device supply voltage V DD has to be higher than V DD min (V DD = V CC– R1.I DD)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 V PEAK> 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.10Standard information regarding manufacturability of Melexis products with different soldering processesOur 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-020Moisture/Reflow Sensitivity Classification for Nonhermetic Solid State Surface Mount Devices(classification reflow profiles according to table 5-2)EIA/JEDEC JESD22-A113Preconditioning 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)EN60749-20Resistance of plastic- encapsulated SMD’s to combined effect of moisture and solderin g heatEIA/JEDEC JESD22-B106 and EN60749-15Resistance to soldering temperature for through-hole mounted devicesIron Soldering THD’s (Through Hole Devices)EN60749-15Resistance to soldering temperature for through-hole mounted devicesSolderability S MD’s (Surface Mount Devices) and THD’s (Through Hole Devices)EIA/JEDEC JESD22-B102 and EN60749-21SolderabilityFor 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 appli cation 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.
