Product details
Overview
MLX90366LVS-AEU-250-SP from Melexis is an AEC-Q100 qualified Triaxis® absolute position sensor IC using Hall-effect technology to measure Bx, By, and Bz magnetic field components. It delivers 12-bit resolution with 10-bit thermal accuracy, SENT output per SAE J2716-2010, on-board diagnostics, and operates across −40 °C to +150 °C for automotive pedal and steering wheel position sensing.
For engineers reviewing the MLX90366LVS-AEU-250-SP datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SENT timing compliance, thermal offset correction capability (enabled in AEU option), DMP-4 package mapping, and validated alternatives for non-contacting rotary/linear position sensing in safety-critical automotive systems.
Technical Context
The MLX90366LVS-AEU-250-SP integrates a 16-bit RISC DSP core running at 10 MHz (2.5 MIPS), performing real-time coordinate rotation (CoRDiC) to compute angular or linear position from raw sine/cosine ADC outputs. Its Triaxis® architecture enables orthogonal and parallel flux density detection (Bx, By, Bz) without external magnets or PCBs when used with IMC® structures.
It implements SENT protocol with Throttle Sensor Format frames, supports programmable multi-point piecewise-linear transfer characteristics (17-point LNR for AEU variant), and includes thermal output offset correction - a feature explicitly enabled in the AEU-250 option code per datasheet Section 14.1.6 and Table 1 legend.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90367LVS-AEU-250-SP | Same DMP-4 package and AEU option, but adds dual-die redundancy and enhanced diagnostics per ISO 26262 ASIL-B requirements. | Required where functional safety mandates dual-channel comparison or lockstep monitoring. | Select MLX90367 if ASIL-B hardware fault tolerance is mandated; otherwise MLX90366LVS-AEU-250-SP suffices for single-channel applications. |
| TLV320ADC3101IRGER | Analog front-end ADC only - lacks on-chip DSP, Triaxis® sensing, SENT output, and magnetic field processing. | Requires external microcontroller, magnet design, and SENT encoder - increases BOM cost and validation effort. | Only viable for custom designs with existing signal processing infrastructure; not a drop-in replacement. |
Compared with MLX90367LVS-AEU-250-SP, the MLX90366LVS-AEU-250-SP offers identical accuracy, thermal offset correction, and SENT timing but omits dual-die redundancy - making it optimal for cost-sensitive ASIL-A or QM applications. Versus TLV320ADC3101IRGER, it delivers complete system-on-chip functionality, eliminating external computation and reducing design cycle time by >6 months.

FAQ
What is the SENT frame period and latency specification for MLX90366LVS-AEU-250-SP?
The MLX90366LVS-AEU-250-SP has a fixed SENT frame period of 882 μs and delivers position data with 1745 μs average latency (FILTER = 1). This includes field sensing, CoRDiC computation, and SENT transmission - meeting real-time control loop requirements for EPS and brake-by-wire systems. The first sync pulse appears within 1.8 ms of power-up, and valid data is available within 6.3 ms.
Does MLX90366LVS-AEU-250-SP support thermal output offset correction, and how is it enabled?
Yes, MLX90366LVS-AEU-250-SP supports thermal output offset correction - a feature explicitly enabled in the AEU option code per datasheet Section 14.1.6. It is factory-configured and active by default; no end-user programming is required. This correction minimizes zero-point drift over temperature, delivering ≤ ±0.3° angular error across −40 °C to +150 °C in rotary applications.
What package type and pin configuration does MLX90366LVS-AEU-250-SP use?
MLX90366LVS-AEU-250-SP uses the DMP-4 (Dual Mold Package) with 4 pins in STD1 1.27 mm pitch configuration. Pinout is VSS (1), VDD (2), OUT (3), VSS (4). Either ground pin may be used, and pin 1 must remain floating if pin 4 is connected - a layout requirement specified in the functional diagram and pinout section of the datasheet.
How does the Triaxis® sensing architecture of MLX90366LVS-AEU-250-SP differ from conventional Hall sensors?
Unlike single-axis Hall sensors, MLX90366LVS-AEU-250-SP's Triaxis® architecture measures all three magnetic field components (Bx, By, Bz) simultaneously using integrated magneto-concentrators. This enables true 3D field vector decoding - allowing absolute rotary position (0–360°) or linear stroke measurement from a single moving magnet, without requiring complex multi-sensor arrays or external flux concentrators.
Is MLX90366LVS-AEU-250-SP qualified for automotive safety standards, and what is its AEC-Q100 grade?
Yes, MLX90366LVS-AEU-250-SP is AEC-Q100 qualified to Grade 0 (−40 °C to +150 °C ambient), validating its reliability for under-hood and transmission-mounted applications. It supports diagnostic features required for ASIL-B decomposition - including SENT CRC error reporting, supply fault detection, and broken-track diagnostics - though full ASIL-B compliance requires system-level implementation beyond the IC alone.
