Product details
Overview
MLX90366LVS-AEU-258-SP from Melexis is a Triaxis® absolute rotary and linear position sensor IC based on Hall-effect technology with SENT output (SAE J2716-2010), 12-bit resolution, 10-bit thermal accuracy, and AEC-Q100 qualification for automotive applications including throttle and steering wheel position sensing.
For engineers reviewing the MLX90366LVS-AEU-258-SP datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, real-world design meaning of key specs, validated pin functions, and confirmed alternative options for automotive-grade non-contacting position sensing.
Technical Context
The MLX90366LVS-AEU-258-SP integrates a 3-axis magnetic field sensor (Bx, By, Bz) with on-chip DSP, RISC CPU (2.5 MIPS @ 10 MHz), and SENT encoder supporting Throttle Position and Secure Sensor frame formats. It performs real-time rectangular-to-polar conversion using CoRDiC to compute absolute angular or linear position from magnet motion.
Its programmable transfer characteristic uses 17-point piecewise-linear (LNR) calibration (AEU variant), supports thermal offset correction, and delivers diagnostics via SENT fast/slow channels-including broken-track, overvoltage, and under-voltage detection-with EEPROM-stored configuration and 48-bit unique ID.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Interface | SENT (SAE J2716-2010 compliant), enabling robust digital transmission over long cables in noisy automotive environments with built-in error reporting. |
| Resolution & Accuracy | 12-bit output resolution with 10-bit thermal accuracy; intrinsic XY linearity error ±1° at 25°C enables high-fidelity angular measurement without external calibration. |
| Operating Range | −40°C to +150°C ambient temperature, qualified per AEC-Q100 Grade 0, supporting under-hood and transmission-mounted applications. |
| Magnetic Sensitivity | Detects orthogonal (Bx, By) and parallel (Bz) flux components up to ±1 T; IMC gain XY = 1.2–1.8× ensures reliable signal capture with low-field magnets (≥70 mT). |
| Timing Performance | SENT frame period = 882 μs; latency from field change to SENT data = 1745 μs (FILTER=1), meeting real-time control loop timing for pedal and throttle systems. |
| Supply & Protection | 4.5–5.5 V nominal supply; integrated overvoltage protection (24 V), undervoltage detection (4.0 V threshold), and short-circuit output current limit (15–18 mA). |
| Programmability | End-user configurable 17-point LNR transfer curve, clamping limits, diagnostic settings, and serial message content stored in 128 B EEPROM with lock capability. |
Pinout & Package
DMP-4 (Dual Mold Package) with 4-pin leadframe, STD4 2.54 mm pitch, RoHS-compliant, designed for direct module integration without PCB-enabling compact, robust sensor assemblies.
| 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 grounded per functional diagram. |
| 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 digital output (open-drain compatible); delivers calibrated position data, diagnostics, and OEM-defined serial messages. |
| 4 | VSS (Ground) | Secondary ground terminal; used as main system ground connection when Pin 1 is left unconnected. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Sensing | Simultaneous Bx, By, Bz detection enables single-chip absolute angle or stroke measurement-eliminating need for dual-Hall or resolver-based solutions. |
| 17-Point Programmable Transfer Curve | AEU-258 variant supports full 17-point LNR calibration, allowing precise linearization across full mechanical range without external lookup tables or host MCU overhead. |
| SENT Diagnostic Reporting | Fast-channel diagnostics (e.g., open-circuit, short-to-battery) and slow-channel enhanced serial messages provide fault visibility without protocol overhead or extra pins. |
| Thermal Offset Correction | On-chip compensation reduces angular error drift over −40°C to +150°C, maintaining ≤±0.3° max error in rotary applications per datasheet spec. |
| No-PCB Module Integration | DMP-4 package allows direct wire bonding to flex or connectorized housing-reducing assembly cost, improving vibration resistance, and eliminating PCB-related failure modes. |
Applications

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-258-SP | Same DMP-4 package and SENT interface, but adds dual-die redundancy and ASIL-B support per ISO 26262. | Required for safety-critical steering angle or brake-by-wire where fault tolerance is mandated. | Select MLX90367 when functional safety compliance (ASIL-B) is required; otherwise MLX90366LVS-AEU-258-SP provides identical core sensing performance at lower cost. |
| TLV493DW2B6HTSA1 | 3D Hall sensor with I²C output, 12-bit resolution, but no SENT, no programmable LNR, and −40°C to +125°C rating. | Suitable for non-automotive industrial position feedback where SENT is not mandated and extended temperature range is unnecessary. | Choose TLV493DW2B6HTSA1 only for cost-sensitive, non-AEC-Q100 applications requiring I²C and moderate temperature range-no drop-in replacement. |
Compared with MLX90367LVS-AEU-258-SP, the MLX90366LVS-AEU-258-SP omits dual-die redundancy and ASIL-B certification but retains identical magnetic performance, SENT protocol, and 17-point calibration-making it optimal for non-safety-critical automotive positions. Versus TLV493DW2B6HTSA1, it delivers automotive-grade thermal stability, SENT robustness, and field-programmable linearity essential for throttle and pedal systems.

Does MLX90366LVS-AEU-258-SP require an external microcontroller to configure its transfer function?
No-MLX90366LVS-AEU-258-SP features on-chip EEPROM and programmable 17-point piecewise-linear (LNR) transfer characteristic. Calibration parameters (e.g., LNRAX–LNRCS) are written once during end-of-line programming using Melexis' PTM tool or compatible SENT host; no external MCU is needed for runtime reconfiguration.
What is the significance of the "AEU-258" option code in MLX90366LVS-AEU-258-SP?
The "AEU" denotes the standard version with 17-point LNR programmability and thermal output offset correction; "258" specifies STD4 2.54 mm pitch DMP-4 packaging with trim-and-form leads. This option enables high-accuracy, temperature-compensated position sensing in compact, PCB-free modules-confirmed in Melexis datasheet revision 002, section 1.1.
Can MLX90366LVS-AEU-258-SP operate without a printed circuit board?
Yes-the MLX90366LVS-AEU-258-SP is qualified for "Reliable NoPCB Module Integration" per its datasheet. Its DMP-4 package supports direct wire bonding to flexible circuits or connectors, eliminating traditional PCBs while maintaining electrical integrity, mechanical robustness, and environmental resilience in automotive modules.
What diagnostic capabilities does MLX90366LVS-AEU-258-SP provide?
The MLX90366LVS-AEU-258-SP delivers comprehensive diagnostics via SENT: fast-channel flags for open-circuit, short-to-battery, short-to-ground, and overtemperature; slow-channel enhanced serial messages with CRC, OEM-defined data, and error codes.
