Product details
Overview
MLX90366LVS-AEU-253-SP from Melexis is an AEC-Q100 qualified Triaxis® absolute position sensor IC using Hall-effect and integrated magneto-concentrator (IMC®) technology to measure Bx, By, and Bz field components. It delivers 12-bit resolution with 10-bit thermal accuracy, SENT output per SAE J2716-2010 (Throttle format), and operates across −40 °C to +150 °C for automotive pedal and steering wheel position sensing.
For engineers reviewing the MLX90366LVS-AEU-253-SP datasheet, pinout, applications, or equivalent options, this page provides verified functional context, SENT timing compliance, thermal offset correction capability, DMP-4 package mapping, and validated alternative options for non-contacting rotary/linear position measurement in harsh environments.
Technical Context
The MLX90366LVS-AEU-253-SP implements a 16-bit RISC DSP core running at 10 MHz (2.5 MIPS) to compute angular or linear position from raw sine/cosine ADC outputs. Its Triaxis® architecture enables orthogonal and parallel flux density sensing (Bx, By, Bz) via on-die IMC®, supporting both rotary (0–360°) and linear displacement decoding without mechanical contact.
It uses SENT serial output with configurable fast channel (throttle position or secure sensor format), slow channel enhanced serial messages, and built-in diagnostics including broken track, over-voltage, under-voltage, and thermal offset correction-enabled specifically in the AEU option code variant per datasheet Section 14.1.6.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Interface | SENT compliant with SAE J2716-2010 Throttle Position format; enables deterministic, noise-immune digital transmission over long cables in automotive ECU environments. |
| Resolution & Accuracy | 12-bit output resolution with 10-bit thermal accuracy; supports ±0.3° angular error max after thermal offset correction in AEU-253 variant. |
| Operating Range | −40 °C to +150 °C ambient; qualified to AEC-Q100 Grade 0, enabling direct placement near engines, pedals, or suspension systems. |
| Magnetic Sensing | Triaxis® 3D field sensing (Bx, By, Bz); intrinsic XY linearity error ≤ ±1° at 25 °C with factory SMISM trim, enabling high-fidelity angle reconstruction. |

| Timing Performance | SENT frame period = 882 μs; latency from field change to SENT data = 1745 μs (FILTER = 1); start-up time to first sync pulse = 1.8 ms. |
| Programmability | User-configurable 17-point piecewise-linear transfer characteristic, discontinuity point, clock-wise direction, and clamping limits stored in 128 B EEPROM. |
Pinout & Package
DMP-4 (Dual Mold Package) with 4-pin leadframe, STD2 2.54 mm pitch, face-up reel packing (RE), RoHS-compliant. Designed for robust no-PCB module integration with exposed die attach pad for thermal and mechanical stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS (Ground) | Primary ground reference; either VSS pin may be used, but Pin 1 must remain floating if Pin 4 is used for grounding. |
| 2 | VDD | Power supply input (4.5–5.5 V); includes internal POR, MT4V startup detection, and over-voltage protection up to +24 V. |
| 3 | OUT | SENT serial output (open-drain, 18 V tolerant); delivers calibrated position data, diagnostics, and OEM-defined serial messages. |
| 4 | VSS (Ground) | Secondary ground terminal; electrically identical to Pin 1; recommended for system grounding when Pin 1 is left unconnected. |
Key Features
| Feature | Design Value |
|---|---|

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-253-SP | Same DMP-4 package and AEU option code, but adds dual-die redundancy and extended diagnostic coverage per ISO 26262. | Required for ASIL-C/D systems where single-point failure mitigation is mandated; not drop-in compatible due to different EEPROM layout and diagnostic enablement. | Select MLX90367LVS-AEU-253-SP only when functional safety certification beyond ASIL-B is required. |
| TLV493DW2B6HTSA1 | 3D Hall sensor with I²C output (not SENT), 12-bit resolution, −40 °C to +125 °C range, no thermal offset correction or programmable LNR. | Suitable for cost-sensitive industrial encoders or consumer devices-not qualified to AEC-Q100 or rated for 150 °C operation. | Choose TLV493DW2B6HTSA1 only for non-automotive applications where SENT interface and extended temperature range are unnecessary. |
Compared with MLX90366LVS-AEU-253-SP, MLX90367LVS-AEU-253-SP adds hardware-level fault containment for ASIL-C, while TLV493DW2B6HTSA1 trades automotive qualification and SENT for lower cost and I²C simplicity-neither offers pin-to-pin compatibility or identical thermal performance.

Frame period is fixed at 882 μs, with optional slow channel messages containing OEM-defined data and diagnostics. The MLX90366LVS-AEU-253-SP supports both standard and secure sensor formats, configurable via EEPROM.
Does the MLX90366LVS-AEU-253-SP support thermal offset correction?
Yes-the MLX90366LVS-AEU-253-SP includes thermal output offset correction enabled by its AEU option code (Section 14.1.6 of the datasheet). This feature reduces angular error to ≤±0.3° over −40 °C to +150 °C without external calibration, distinguishing it from ADU or ADS variants which lack this capability. The MLX90366LVS-AEU-253-SP applies correction in real time using on-chip temperature sensing and stored coefficients.
What package type and dimensions does the MLX90366LVS-AEU-253-SP use?
The MLX90366LVS-AEU-253-SP uses the DMP-4 (Dual Mold Package) with STD2 2.54 mm pitch, as specified in Section 19.3 of the datasheet. It features four terminals (VSS, VDD, OUT, VSS), no PCB required, and is optimized for direct integration into plastic housings. The package is RoHS-compliant (DMP-4), with face-up reel packing (RE) and a sensitive spot positioned per Figure 42.
Can the MLX90366LVS-AEU-253-SP be used for linear position sensing?
Yes-the MLX90366LVS-AEU-253-SP supports both absolute rotary and linear position sensing via Triaxis® 3D field measurement. When paired with a properly designed magnetic circuit (e.g., moving magnet along a linear path), it decodes Bx, By, Bz to compute stroke displacement. Applications include pedal position, float-level sensing, and ride height detection-all confirmed in the official datasheet Applications section.
What diagnostic capabilities does the MLX90366LVS-AEU-253-SP provide?
The MLX90366LVS-AEU-253-SP integrates on-chip diagnostics including broken VDD/VSS track detection, over-voltage and under-voltage monitoring, SENT frame CRC checking, and thermal fault reporting. Diagnostic status is embedded in SENT fast-channel status bits and slow-channel serial messages. These features are enabled by default and configurable via EEPROM settings such as DIAGSETTINGS (0x4080 default), as documented in Section 14.6.
