Product details
Overview
MLX90290LSE-AAA-553-SP from Melexis is a high-speed, factory-trimmed linear Hall-effect sensor IC in TSOT-3L package, operating from 5 V supply with 39 mV/mT sensitivity and 650 ppm/°C magnet thermal drift compensation. It delivers ratiometric analog output (quiescent level at 50% VDD), ±1.5% linearity, and 25 kHz signal bandwidth for precision position and current sensing in automotive powertrain and industrial motor control systems.
For engineers reviewing the MLX90290LSE-AAA-553-SP datasheet, pinout, applications, or equivalent options, this page provides verified technical context, validated pin functions, real-world application mappings, and confirmed alternative options aligned to AEC-Q100 Grade 0 (-40°C to +150°C) requirements.
Technical Context
The MLX90290LSE-AAA-553-SP integrates a CMOS Hall plate with advanced offset cancellation, voltage regulator, and analog output driver in a single die. Its ratiometric output scales linearly with both magnetic flux density and supply voltage, with quiescent output fixed at 50% VDD under zero field.
It employs chopping modulation at 900 kHz to suppress offset drift and enables fast power-on response (<70 µs) for micro-power gating. The 650 ppm/°C TCS option (Z=3) is calibrated to compensate ferrite magnet drift across -40°C to +150°C, supporting robust operation without external calibration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Sensitivity | 39 mV/mT @ 5 V - delivers 1.95 V output swing per 50 mT field change, enabling high-resolution analog position feedback |
| Thermal Coefficient (TCS) | 650 ppm/°C - actively compensates ferrite magnet drift over full temperature range, reducing system-level calibration burden |
| Signal Bandwidth | 25 kHz - supports real-time motor commutation timing and fast-response current sensing up to 10 kRPM |
| Linearity Error | ±1.5% - ensures sub-degree angular accuracy in rotary position sensing and <0.5 mm error in linear displacement |
| Power-On Time | ≤70 µs - enables rapid wake-up from sleep mode in battery-powered ECUs and gate drivers |
| Supply Voltage Range | 3.15 V to 5.5 V - compatible with standard 5 V automotive rails and tolerant of transient dips during cranking |
| AEC-Q100 Qualification | Grade 0 (−40°C to +150°C) - certified for engine bay, transmission, and inverter applications without derating |
Pinout & Package
MLX90290LSE-AAA-553-SP uses the RoHS-compliant TSOT-3L surface-mount package (3.0 × 2.6 × 0.9 mm), optimized for automated assembly and high-density PCB layouts in automotive modules.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VDD | 5 V nominal supply input; requires ≥0.1 µF ceramic bypass capacitor placed adjacent to pin for stable regulation and noise immunity |
| 2 | OUT | Analog ratiometric output; delivers 0.25–4.75 V swing (50% VDD quiescent) into 5 kΩ–∞ load; supports direct ADC interface without amplification |
| 3 | GND | Reference ground return; must be low-impedance path to minimize offset error and EMI coupling in noisy environments |
Key Features
| Feature | Design Value |
|---|---|
| Factory-programmed sensitivity & TCS | Eliminates post-silicon trimming; 39 mV/mT and 650 ppm/°C are laser-trimmed at wafer level for guaranteed performance |
| Chopped Hall architecture | 900 kHz chopping frequency reduces 1/f noise and thermal drift to <±0.1 mV over temperature, enabling stable DC measurements |
| Ratiometric output | Output scales with VDD - preserves measurement accuracy despite supply rail variation (e.g., 4.5–5.5 V), simplifying power design |
| Fast start-up time | ≤70 µs power-on settling allows integration into duty-cycled subsystems (e.g., EPS torque sensing only during steering events) |
| Automotive qualification | AEC-Q100 Grade 0 compliance ensures reliability in under-hood environments with 165°C max junction temperature rating |

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-532-RE | 50 mV/mT sensitivity, 2000 ppm/°C TCS - higher gain but steeper thermal compensation slope | Better suited for NdFeB magnets with strong negative drift; less optimal for ferrite where 650 ppm/°C matches typical drift profile | Select when magnet type and temperature profile demand tighter thermal tracking than 650 ppm/°C provides |
| MLX90363KGO-ABA-000-TU | Triaxis 3D Hall IC with digital SPI output; 16-bit resolution; programmable gain and offset; no ratiometric analog output | Enables multi-axis sensing and on-chip linearization but requires digital interface and firmware support | Choose for space-constrained designs needing angular position (0–360°) or when digital bus integration outweighs analog simplicity |
Compared with MLX90290LSE-AAA-553-SP, the -532-RE offers higher sensitivity and stronger thermal compensation for NdFeB magnets, while the MLX90363KGO-ABA-000-TU replaces analog simplicity with digital flexibility and 3D capability-requiring trade-offs in BOM count, layout area, and software overhead.

FAQ
What is the supply voltage range and quiescent current of MLX90290LSE-AAA-553-SP?
The MLX90290LSE-AAA-553-SP operates from 3.15 V to 5.5 V with typical supply current of 5 mA. Its quiescent output voltage is precisely 50% of VDD under zero magnetic field, and it maintains ratiometric behavior across the full supply range - meaning output scaling remains proportional to VDD, preserving measurement integrity during rail fluctuations. This behavior is intrinsic to the MLX90290LSE-AAA-553-SP architecture and verified per Table 5 in the official datasheet.
How does the 650 ppm/°C thermal coefficient (TCS) function in MLX90290LSE-AAA-553-SP?
The 650 ppm/°C TCS in MLX90290LSE-AAA-553-SP is factory-programmed to counteract the positive thermal drift of common ferrite magnets. It adjusts the sensitivity slope dynamically so that output voltage remains stable across −40°C to +150°C - verified by characterization data in Table 7 and Figure 12.2 of the MLX90290LSE-AAA-553-SP datasheet. This eliminates need for external temperature compensation circuits.
Can MLX90290LSE-AAA-553-SP be used with a 3.3 V supply?
No - MLX90290LSE-AAA-553-SP is configured for 5 V nominal operation (option code "5" in Y-field). While the absolute maximum rating allows down to 3.15 V, its factory trim, sensitivity (39 mV/mT), and TCS (650 ppm/°C) are calibrated at 5 V. Using 3.3 V would reduce output swing and invalidate thermal compensation; for 3.3 V systems, MLX90290LSE-AAA-353-RE (39 mV/mT @ 3.3 V) is the correct variant.
What is the signal bandwidth and phase shift of MLX90290LSE-AAA-553-SP?
The MLX90290LSE-AAA-553-SP has a −3 dB signal bandwidth of 25 kHz and phase shift of 2.4° at 1 kHz (TSOT-3L package), as specified in Table 6. These values are measured under defined test conditions (B < 0.4/SREL) and reflect the internal filtering associated with its Z=3 (650 ppm/°C) configuration. Bandwidth supports real-time motor commutation up to 10 kRPM without latency-induced torque ripple.
Is MLX90290LSE-AAA-553-SP pin-compatible with other MLX90290 variants in TSOT-3L?
Yes - all MLX90290 variants in SE (TSOT-3L) package share identical pinout (VDD–OUT–GND), mechanical footprint, and solder reflow profile. The MLX90290LSE-AAA-553-SP can be substituted for other SE-coded variants (e.g., -510-RE, -530-RE) on the same PCB without layout changes, provided system-level requirements (supply voltage, sensitivity, TCS) align with the functional specification.
