Product details
Overview
MLX90366LVS-ADU-250-RE from Melexis is an AEC-Q100 qualified Triaxis® absolute position sensor IC using Hall-effect 3D magnetic field sensing (Bx, By, Bz) to deliver 12-bit angular/linear position output via SENT protocol (SAE J2716-2010), with 10-bit thermal accuracy and on-board diagnostics. It operates from −40 °C to +150 °C and enables non-contacting potentiometer replacement in throttle and steering systems.
For engineers reviewing the MLX90366LVS-ADU-250-RE datasheet, pinout, applications, or equivalent options, this page delivers verified functional context, SENT timing compliance, thermal offset correction capability, DMP-4 package mapping, and automotive-grade diagnostic coverage - all confirmed for the ADU-250 variant.
Technical Context
The MLX90366LVS-ADU-250-RE integrates a 16-bit RISC DSP core running at 10 MHz (2.5 MIPS), performing real-time CoRDiC-based rectangular-to-polar conversion of orthogonal magnetic field components. Its internal IMC structure provides calibrated gain for X/Y (1.2–1.8×) and Z (1.1–1.3×) axes, with k-factor trimming (1.0–1.5) enabling axis-mismatch compensation.
This variant supports 3-point piecewise-linear (3-Pts LNR) programmable transfer characteristic, SENT Throttle Sensor format output, and thermal offset correction disabled (per ADU-xxx definition). It delivers SENT frames every 882 μs with 441 μs internal angle measurement period and 1745 μs total field-to-data latency under FILTER = 1 configuration.

| Package | DMP-4 (Dual Mold Package), STD1 1.27 mm pitch - surface-mount, RoHS-compliant, PCB-less module integration capable. |
Pinout & Package
DMP-4 is a 4-pin dual-mold surface-mount package with exposed die pad for thermal dissipation and mechanical stability. Pin 1 and Pin 4 are both VSS (ground), with Pin 1 designated as primary ground and Pin 4 usable as secondary ground or left floating per layout guidance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS (Ground) | Primary ground reference; required for biasing analog front-end and digital core; must be connected to low-impedance system ground. |
| 2 | VDD | Power supply input (4.5–5.5 V); includes internal POR (2.25 V threshold) and MT4V startup detection (4.0 V). |
| 3 | OUT | SENT serial output (open-drain, 18 V tolerant); delivers 29-bit frames with fast-channel position data and slow-channel diagnostics. |
| 4 | VSS (Ground) | Secondary ground terminal; may be used to reduce ground loop impedance or left unconnected if layout constraints require single-point grounding. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Transfer Characteristic | 3-point piecewise-linear (3-Pts LNR) calibration - allows end-user tuning of output curve for magnet nonlinearity and mechanical hysteresis compensation. |
| SENT Output Compliance | Fully compliant with SAE J2716-2010 Throttle Sensor format - eliminates need for external protocol translators in engine control modules. |
| On-Chip Diagnostics | Dual-level diagnostic reporting (fast channel error codes + slow channel enhanced serial messages) - supports ISO 26262 diagnostic coverage analysis. |
| Thermal Offset Correction | Not enabled in ADU-250 variant - simplifies calibration workflow where thermal drift is managed externally or within ECU software. |
| No-PCB Module Integration | DMP-4 package supports direct wire-bonding to sensor housing - removes PCB reliability risks and enables compact, high-vibration-resistant assemblies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90366LVS-AEV-250-RE | 17-point LNR calibration and extended EEPROM programmability - adds higher-order curve fitting vs. ADU-250's 3-point LNR. | Required for applications needing finer nonlinearity correction (e.g., high-precision steering angle in ADAS). | Select AEV-250 when magnet geometry induces complex field distortion requiring >3 calibration points. |
| MLX90367LVS-ADU-250-RE | Dual-die version with independent X/Y and Z channel outputs - enables redundant sensing and cross-checking not available in single-die MLX90366. | Suitable for ASIL-D systems requiring hardware-level fault detection beyond MLX90366's diagnostic coverage. | Choose MLX90367 for safety-critical applications where dual-channel independence is mandated by ISO 26262. |
Compared with MLX90366LVS-ADU-250-RE, the AEV-250 offers superior magnetic nonlinearity compensation at the cost of longer programming time, while the MLX90367 provides true hardware redundancy but requires additional ECU processing for dual-channel arbitration.

FAQ
What is the SENT frame structure used by the MLX90366LVS-ADU-250-RE?
The MLX90366LVS-ADU-250-RE transmits SENT frames in Throttle Sensor format per SAE J2716-2010, with 29 bits per frame: 4-bit sync, 12-bit position data (MSB-aligned), 4-bit CRC, and 9-bit status/diagnostic bits. Frame period is fixed at 882 μs, and the IC supports pause pulses for multi-sensor synchronization. This structure is factory-configured for ADU-250 and cannot be changed to Secure Sensor format.
Does the MLX90366LVS-ADU-250-RE support thermal output offset correction?
No, the MLX90366LVS-ADU-250-RE does not include thermal output offset correction. That feature is exclusive to AxX-xxx variants (e.g., ADX-250). The ADU-250 variant uses 3-point LNR calibration only and relies on external ECU compensation or mechanical design to manage thermal drift, which is specified as ±60 LSB₁₅ over −40 °C to +125 °C.
What is the maximum magnetic field strength the MLX90366LVS-ADU-250-RE can measure?
The MLX90366LVS-ADU-250-RE supports magnetic flux densities up to ±1 T absolute maximum, but optimal performance is achieved within defined operating ranges: BX/BY up to 70 mT (beyond which IMC saturation increases linearity error), and BZ up to 126 mT. The magnetic flux norm √[BX² + BY² + (Bz/1.2)²] should remain ≥20 mT to maintain signal-to-noise ratio.
Can the MLX90366LVS-ADU-250-RE be used without a printed circuit board?
Yes, the MLX90366LVS-ADU-250-RE is qualified for "Reliable NoPCB Module Integration" per its datasheet. Its DMP-4 package allows direct wire bonding to metal housings or flexible substrates, eliminating traditional PCBs. This reduces assembly cost, improves mechanical robustness, and enhances resistance to thermal cycling and vibration - validated for automotive under-hood environments.
How is the MLX90366LVS-ADU-250-RE calibrated for different magnet configurations?
The MLX90366LVS-ADU-250-RE is calibrated using its 3-point piecewise-linear (3-Pts LNR) programmable transfer characteristic. Users configure LNRAX/LNRAY/LNRAS and LNRBX/LNRBY/LNRBS coordinates via I²C or SENT slow channel to map raw magnetic input to desired output angle or stroke. Factory-trimmed parameters (SMISM, k, MAPXYZ) ensure baseline accuracy before end-user calibration.
