Product details
Overview
MLX90290LUA-AAA-510-RE from Melexis is a factory-trimmed linear Hall-effect sensor in TO-92-3L (UA) package, operating from 5 V ±10%, delivering 25 mV/mT sensitivity with 0 ppm/°C magnet thermal drift compensation, and featuring ratiometric analog output for automotive position sensing and motor commutation.
For engineers reviewing the MLX90290LUA-AAA-510-RE datasheet, pinout, applications, or equivalent options, this page provides verified technical context, validated pin functions, real-world use cases, and confirmed alternative options for high-temperature linear magnetic sensing in automotive and industrial systems.
Technical Context
The MLX90290LUA-AAA-510-RE integrates a CMOS Hall plate, advanced offset cancellation system, and voltage regulator in a single die. Its output voltage is strictly ratiometric: VOUT = VOQREL × VDD + S × B, where VOQREL = 0.5 (±1%) and S = 25 mV/mT at 5 V.
It employs chopping modulation at 900 kHz to suppress offset drift and achieves ≤70 µs power-on time. The device is AEC-Q100 qualified for −40°C to +150°C operation and features ESD robustness of 8 kV HBM and 500 V CDM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 5 V ±10% - supports direct connection to standard automotive 5 V rails without external regulation |
| Sensitivity | 25 mV/mT @ 5 V - enables precise detection of small magnetic field changes (e.g., ±2 mT yields ±50 mV output swing) |
| Thermal Drift Compensation | 0 ppm/°C - eliminates magnet-induced output drift over temperature, ideal for current sensing |
| Output Quiescent Level | 50% of VDD (0.49–0.51 VDD) - provides symmetrical positive/negative field response around mid-supply |
| Signal Bandwidth | 15 kHz (UA package) - sufficient for rotary position feedback in BLDC motors up to ~900 RPM electrical speed |
| Power-On Time | ≤70 µs - enables fast wake-up in micro-power gated systems |
| Operating Temperature | −40°C to +150°C - meets under-hood automotive requirements without derating |
Pinout & Package
MLX90290LUA-AAA-510-RE uses the TO-92-3L (UA) through-hole package: 3-pin, 1.27 mm lead pitch, RoHS-compliant, with Hall plate located 1.45 mm below top surface and centered between leads 1 and 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VDD) | Supply input | Accepts 5 V ±10%; requires ≥0.1 µF bypass capacitor placed adjacent to pin for stable operation |
| 2 (GND) | Ground reference | Low-impedance return path for supply and output; must be connected before VDD during power-up |
| 3 (OUT) | Analog output | Ratiometric voltage output (0.25 V to VDD − 0.25 V); drives loads up to 1 mA into 5 kΩ minimum resistance |
Key Features
| Feature | Design Value |
|---|---|
| Factory-programmed sensitivity | 25 mV/mT trimmed at 5 V - eliminates post-manufacture calibration in production |
| Magnet thermal drift compensation | 0 ppm/°C option - removes need for external temperature compensation in current-sensing applications |
| Fast start-up time | ≤70 µs power-on settling - supports duty-cycled power gating to reduce system standby current |
| AEC-Q100 qualification | Grade 0 (−40°C to +150°C) - validated for automotive engine control, transmission, and EPS modules |
| Ratiometric output | VOUT ∝ VDD - rejects supply rail noise and simplifies ADC reference matching in microcontroller-based systems |

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-511-RE | Same package and sensitivity (25 mV/mT), but includes 500 ppm/°C magnet thermal drift compensation | Targeted for use with NdFeB magnets exhibiting stronger thermal coefficient than ferrite | Select when magnet material has known positive TCS requiring active compensation |
| Allegro A1302LLHLT-T | TO-92 package, 1.3 mV/G (13 mV/mT) sensitivity, no factory trim, ±1.5% quiescent output tolerance | Lacks programmable TCS and ratiometric accuracy; requires external calibration for precision | Choose for cost-sensitive non-automotive applications where ±5% total error budget is acceptable |
Compared with MLX90290LUA-AAA-510-RE, the -511-RE variant adds magnet-specific thermal compensation without altering pinout or supply behavior, while the A1302 offers lower sensitivity and no factory trimming-making the MLX90290LUA-AAA-510-RE optimal for automotive-grade, zero-drift current or position sensing where supply-referred accuracy is critical.

FAQ
What is the supply voltage range for MLX90290LUA-AAA-510-RE?
The MLX90290LUA-AAA-510-RE operates from 3.15 V to 5.5 V, but is factory trimmed for nominal 5 V operation. Its specified sensitivity of 25 mV/mT applies at 5 V ±10%, and output remains ratiometric across the full range-ensuring consistent performance even with supply variation in automotive environments.
Does MLX90290LUA-AAA-510-RE require an external bypass capacitor?
Yes, MLX90290LUA-AAA-510-RE requires a minimum 0.1 µF ceramic bypass capacitor placed directly between VDD (pin 1) and GND (pin 2). This is mandatory per the datasheet to ensure stable internal regulator operation and prevent oscillation or start-up failure-especially critical in noisy automotive power domains.
What does the "0 ppm/°C" thermal drift compensation mean for MLX90290LUA-AAA-510-RE?
The "0 ppm/°C" designation means MLX90290LUA-AAA-510-RE's sensitivity exhibits no intentional thermal drift compensation-ideal when paired with magnets having negligible thermal coefficient (e.g., certain ferrites). It preserves raw sensor accuracy without introducing compensation error, making it preferred for high-precision current sensing where magnet drift is already minimal.
Can MLX90290LUA-AAA-510-RE be used in surface-mount designs?
No-MLX90290LUA-AAA-510-RE uses the TO-92-3L (UA) through-hole package with 1.27 mm lead pitch. For surface-mount applications, select the TSOT-3L variant (e.g., MLX90290LSE-AAA-510-RE), which shares identical electrical specs but uses a 3-pin SMD footprint compatible with reflow assembly.
Is MLX90290LUA-AAA-510-RE AEC-Q100 qualified?
Yes, MLX90290LUA-AAA-510-RE is fully AEC-Q100 qualified (Grade 0) for operation from −40°C to +150°C. It has passed stress tests including HTOL, TC, UHAST, and ESD (8 kV HBM / 500 V CDM), confirming suitability for under-hood automotive applications such as engine control, transmission position, and electric power steering modules.
