Product details
Overview
MLX90290LSE-AAA-521-RE from Melexis is a high-speed, factory-trimmed linear Hall-effect sensor IC in TSOT-3L package, operating from 5 V ±10%, delivering 31.25 mV/mT sensitivity and 500 ppm/°C magnet thermal drift compensation. It features ratiometric analog output (50% VDD quiescent level), AEC-Q100 qualification for automotive use, and 25 kHz signal bandwidth - deployed in motor commutation and rotary position sensing within engine control units.
For engineers reviewing the MLX90290LSE-AAA-521-RE datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, exact pin functions, real-world application mappings, and validated alternative options for position, current, and speed sensing designs requiring automotive-grade reliability and fast magnetic response.
Technical Context
The MLX90290LSE-AAA-521-RE integrates a CMOS Hall plate with dynamic offset cancellation (chopping at 900 kHz), voltage regulator, and rail-to-rail analog output driver. Its output voltage follows VOUT = VDD × (VOQREL + SREL × B), where VOQREL = 0.5 and SREL is factory trimmed to 31.25 mV/mT @ 5 V with 500 ppm/°C TCS for ferrite magnet compensation.
This variant uses internal filtering optimized for Z=1 (500 ppm/°C) configuration, yielding 25 kHz bandwidth and 2.4° phase shift at 1 kHz - enabling accurate high-frequency magnetic field tracking in noisy environments without external RC networks.
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 | 31.25 mV/mT @ 5 V - enables precise detection of small magnetic field changes (e.g., <0.1 mT resolution at 1 mA load). |
| Thermal Drift Compensation | 500 ppm/°C - actively compensates for ferrite magnet flux loss over temperature, maintaining linearity across –40°C to +150°C. |
| Signal Bandwidth | 25 kHz - supports real-time rotor position capture up to 150 kRPM in BLDC motor commutation. |
| Quiescent Output | 2.5 V @ 5 V supply - ratiometric 50% VDD offset simplifies ADC reference alignment and fault detection. |
| Power-On Time | 40–70 µs - enables micro-power wake-up in start-stop systems with minimal latency after supply assertion. |
| AEC-Q100 Grade | Grade 0 (–40°C to +150°C) - qualified for under-hood automotive applications including transmission and engine control modules. |
Pinout & Package
MLX90290LSE-AAA-521-RE is housed in a RoHS-compliant TSOT-3L surface-mount package (3.0 × 2.6 × 0.9 mm), optimized for automated placement and high-density PCB layouts. The Hall plate is located 0.80 mm below the top surface, centered between pins 1 and 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VDD) | Supply Input | Accepts 3.15–5.5 V; requires ≥0.1 µF bypass capacitor placed adjacent to pin for stable operation and EMI suppression. |
| 2 (GND) | Ground Reference | Low-impedance return path for internal regulator and output stage; must be connected before VDD during power-up. |
| 3 (OUT) | Analog Output | Ratiometric voltage output (0.25–4.75 V range at 5 V supply); drives loads up to 1 kΩ directly; supports 10 nF capacitive loading with RS = 50 Ω. |
Key Features
| Feature | Design Value |
|---|---|
| Factory-programmed sensitivity & TCS | Eliminates post-silicon calibration; 31.25 mV/mT and 500 ppm/°C are laser-trimmed at wafer level for guaranteed performance. |
| Chopped Hall architecture | 900 kHz chopping frequency cancels offset drift and 1/f noise, achieving <±1.5% linearity and <±5% sensitivity accuracy over temperature. |
| Fast power-on response | 40–70 µs startup time allows integration into low-duty-cycle sensing nodes (e.g., crankshaft position wake-up triggers). |
| Automotive-grade robustness | 8 kV HBM ESD rating, –40°C to +150°C operation, and 165°C max junction temperature support harsh under-hood deployment. |
| Ratiometric output | Output scales with VDD - removes dependency on stable reference voltage and simplifies system-level error budgeting. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear Hall sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90290LSE-AAA-520-RE | No thermal drift compensation (0 ppm/°C TCS) - intended for current sensing with stable magnets. | Lacks magnet temperature compensation; unsuitable for rotary position with ferrite magnets over wide temperature range. | Select only when using AlNiCo or samarium-cobalt magnets, or when system-level software compensation is implemented. |
| MLX90363KGO-ABA-000-TU | Triaxis 3D Hall IC with SPI digital output; higher integration (on-chip DSP, EEPROM, diagnostics); 16-bit resolution. | Replaces analog output with programmable digital interface; supports advanced angle calculation and fault reporting. | Choose when digital communication, multi-axis sensing, or ASIL-B compliance is required - not a drop-in replacement. |
Compared with MLX90290LSE-AAA-521-RE, the -520-RE variant trades magnet thermal compensation for wider bandwidth in current sensing, while the MLX90363 offers digital intelligence at higher cost and layout complexity - making MLX90290LSE-AAA-521-RE optimal for cost-sensitive, analog-output rotary position systems needing guaranteed ferrite magnet stability.

FAQ
What is the supply voltage range supported by the MLX90290LSE-AAA-521-RE?
The MLX90290LSE-AAA-521-RE operates from 3.15 V to 5.5 V, with nominal 5 V ±10% specified in its ordering code. It includes an internal voltage regulator, allowing stable performance across this range. At 5 V supply, the device delivers its rated 31.25 mV/mT sensitivity and 500 ppm/°C thermal compensation - critical for consistent output in automotive 5 V rail environments. Operation outside this range may cause undefined behavior or damage.
How does the 500 ppm/°C thermal coefficient (TCS) function in the MLX90290LSE-AAA-521-RE?
The 500 ppm/°C TCS in MLX90290LSE-AAA-521-RE is factory-programmed to counteract the negative temperature coefficient of ferrite magnets. It adjusts the sensitivity slope dynamically so that magnetic field measurements remain accurate across –40°C to +150°C. This compensation is embedded in the analog front-end and requires no external components or firmware - ensuring that MLX90290LSE-AAA-521-RE maintains <±1.5% linearity in rotary position applications without software correction.
Can the MLX90290LSE-AAA-521-RE be used in current sensing applications?
Yes, the MLX90290LSE-AAA-521-RE can be used for open-loop current sensing by measuring the magnetic field around a conductor. Its 31.25 mV/mT sensitivity and ratiometric output simplify interface to standard ADCs. However, because it includes 500 ppm/°C magnet compensation (optimized for position sensing with ferrite), users should verify magnet type and thermal profile - for pure current sensing with stable magnets, the -520-RE (0 ppm/°C) variant may offer better raw bandwidth and lower noise.
What is the significance of the "SE" package code in MLX90290LSE-AAA-521-RE?
The "SE" in MLX90290LSE-AAA-521-RE denotes the TSOT-3L (Thin Small Outline Transistor) surface-mount package - a 3.0 × 2.6 × 0.9 mm RoHS-compliant leaded package with gull-wing leads. It enables high-density automated assembly, superior thermal resistance (230°C/W junction-to-ambient), and compatibility with standard reflow profiles. Unlike the UA (TO-92) variant, SE supports finer pitch layouts and eliminates through-hole drilling - making MLX90290LSE-AAA-521-RE ideal for compact automotive modules.
Does the MLX90290LSE-AAA-521-RE require external filtering or conditioning circuitry?
No, the MLX90290LSE-AAA-521-RE includes internal filtering optimized for its 500 ppm/°C TCS option (Z=1), delivering 25 kHz bandwidth and 2.4° phase shift at 1 kHz - sufficient for most motor commutation and position tasks. Only a 0.1 µF ceramic bypass capacitor between VDD and GND is mandatory. External RC networks are unnecessary unless operating in extreme EMC environments, where Melexis recommends adding Rs ≥ 50 Ω and C2 = 1–10 nF on the output per Application Note AN-012.
