Product details
Overview
MLX90290LUA-AAA-622-CR from Melexis is a factory-trimmed linear Hall-effect sensor in TO-92-3L (UA) package, operating from 5 V supply with 31.25 mV/mT sensitivity and +2000 ppm/°C magnet thermal drift compensation. It delivers ratiometric analog output (quiescent level at 50% VDD), supports -40°C to +150°C automotive-grade operation, and is AEC-Q100 qualified for motor commutation and rotary position sensing.
For engineers reviewing the MLX90290LUA-AAA-622-CR datasheet, pinout, applications, or equivalent options, this page provides verified technical context, validated pin functions, confirmed automotive-grade specifications, and real-world application implementation guidance for high-speed magnetic sensing in harsh environments.
Technical Context
The MLX90290LUA-AAA-622-CR integrates a Hall plate, chopper-stabilized offset cancellation circuitry, voltage regulator, and analog output driver in mixed-signal CMOS. Its ratiometric output scales linearly with both magnetic flux density and supply voltage, with quiescent output fixed at 50% VDD under zero field.
It features 900 kHz chopping frequency for noise immunity, 30 kHz signal bandwidth (Z=2 variant), and internal thermal compensation tuned for ferrite magnets. The device achieves ±1.5% linearity and ±5% sensitivity accuracy over temperature, with fast 40–70 µs power-on time suitable for micro-power gating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 5 V ±10% - matches standard automotive rail; enables direct interface with 5 V microcontrollers without level-shifting. |
| Sensitivity | 31.25 mV/mT @ 5 V - delivers high-resolution analog output for precise position detection down to ~0.032 mT per LSB. |
| Thermal Drift Compensation | +2000 ppm/°C - actively compensates for ferrite magnet B-H curve shift across -40°C to +150°C. |
| Output Type | Ratiometric analog voltage - output scales with VDD, eliminating supply variation errors in measurement systems. |
| Operating Temperature | -40°C to +150°C - certified for under-hood automotive use and industrial motor control environments. |
| Signal Bandwidth | 30 kHz - supports high-speed rotor position tracking up to ~1.8 million RPM equivalent electrical frequency. |
| AEC-Q100 Grade | Grade 0 - qualified for automotive applications requiring highest reliability and extended temperature performance. |
Pinout & Package
MLX90290LUA-AAA-622-CR uses the TO-92-3L (UA) through-hole package with 2.54 mm lead pitch (trim-and-form configuration), RoHS-compliant, and rated for 180°C/W junction-to-ambient thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VDD) | Supply input | 5 V power rail connection; requires ≥0.1 µF bypass capacitor placed adjacent to pin for stable regulation and noise immunity. |
| 2 (GND) | Ground reference | Analog ground return path; must be low-impedance and routed separately from digital or power grounds to avoid offset errors. |
| 3 (OUT) | Analog output | Ratiometric voltage output (0.25 V to 4.75 V range at 5 V supply); drives loads up to 1 mA with ≤5 Ω source impedance. |
Key Features
| Feature | Design Value |
|---|---|
| Factory-programmed sensitivity & TCS | Eliminates post-manufacturing calibration; 31.25 mV/mT and +2000 ppm/°C are laser-trimmed during production for consistent system-level accuracy. |
| Chopper-stabilized architecture | 900 kHz chopping suppresses 1/f noise and eliminates thermal drift-induced offset errors, enabling stable DC field measurement. |
| Fast power-on time | 40–70 µs startup enables micro-power gating in battery-operated sensors, reducing average current in intermittent-read applications. |
| High ESD robustness | 8 kV HBM rating allows safe handling in standard assembly lines without special ESD controls beyond basic precautions. |
| Automotive qualification | AEC-Q100 Grade 0 compliance ensures reliability for safety-critical automotive subsystems including EPS and transmission control. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear Hall sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90290LUA-AAA-620-CR | Same package and sensitivity (31.25 mV/mT), but 0 ppm/°C TCS - no internal magnet thermal compensation. | Targeted for current sensing where magnet drift is irrelevant; unsuitable for rotary position with ferrite magnets. | Select only when using AlNiCo or samarium-cobalt magnets, or when external temperature compensation is implemented. |
| MLX90290LSE-AAA-522-RE | TSOT-3L surface-mount package, identical 31.25 mV/mT sensitivity and +2000 ppm/°C TCS, same 5 V supply. | Requires PCB re-layout for SMT assembly; better thermal dissipation (230°C/W vs 180°C/W) but lower ESD margin (500 V CDM vs 8 kV HBM). | Choose for space-constrained designs needing automated placement; verify layout for EMC in noisy motor environments. |
Compared with MLX90290LUA-AAA-622-CR, the -620-CR variant lacks magnet thermal compensation-making it unfit for high-accuracy rotary position with ferrite-and the -522-RE offers identical sensing performance in a smaller SMT footprint but demands revised PCB design and tighter ESD handling protocols.

FAQ
What is the supply voltage range supported by MLX90290LUA-AAA-622-CR?
The MLX90290LUA-AAA-622-CR operates from 4.5 V to 5.5 V (5 V ±10%). It is not rated for 3.3 V operation - attempting to power MLX90290LUA-AAA-622-CR at 3.3 V may result in undefined behavior, failure to power on, or violation of absolute maximum ratings. Always use 5 V nominal supply as specified in the ordering code.
Does MLX90290LUA-AAA-622-CR require an external bypass capacitor?
Yes, MLX90290LUA-AAA-622-CR requires a minimum 0.1 µF ceramic bypass capacitor placed directly between VDD and GND pins, as close as possible to the device. This capacitor stabilizes the internal voltage regulator and suppresses high-frequency noise; omitting it causes output instability, increased offset drift, and potential malfunction during load transients.
What does the "622" in MLX90290LUA-AAA-622-CR signify?
The "622" in MLX90290LUA-AAA-622-CR decodes as: "6" = 5 V supply option with 2.54 mm lead pitch (trim-and-form), "2" = 31.25 mV/mT sensitivity at 5 V, and "2" = +2000 ppm/°C magnet thermal coefficient (TCS) for ferrite magnet compensation - all factory-laser-trimmed and permanently set.
Can MLX90290LUA-AAA-622-CR be used for bidirectional magnetic field measurement?
Yes, MLX90290LUA-AAA-622-CR supports bidirectional measurement: its ratiometric output spans 0.25 V to 4.75 V at 5 V supply, centered at 2.5 V (50% VDD) for zero field. Negative fields drive output below 2.5 V; positive fields drive it above - enabling full ±40 mT range with ±1.5% linearity and symmetric response.
Is MLX90290LUA-AAA-622-CR pin-compatible with other MLX90290 variants in UA package?
Yes, all MLX90290 UA-package variants (e.g., MLX90290LUA-AAA-510-BU, MLX90290LUA-AAA-620-CR) share identical TO-92-3L pinout: Pin 1 = VDD, Pin 2 = GND, Pin 3 = OUT. Mechanical lead pitch differs (1.27 mm vs 2.54 mm), but electrical connectivity and function are fully preserved across UA options.
