Product details
Overview
MLX90366LVS-AEU-258-RX from Melexis is a Triaxis® monolithic Hall-effect position sensor IC that measures absolute rotary or linear position via orthogonal and parallel magnetic flux components (Bx, By, Bz). 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 throttle and steering applications.
For engineers reviewing the MLX90366LVS-AEU-258-RX datasheet, pinout, applications, or equivalent options, key selection considerations include SENT protocol compliance, 17-point programmable transfer characteristic, thermal offset correction capability, AEC-Q100 qualification, and DMP-4 package integration without PCB.
Technical Context
The MLX90366LVS-AEU-258-RX 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 uses integrated magneto-concentrators (IMC®) to sense all three magnetic field components simultaneously, enabling robust non-contact position decoding independent of magnet orientation.
It supports SENT output in Throttle Sensor or Secure Sensor format with fast-channel diagnostics and slow-channel enhanced serial messages. The AEU-258 variant includes 17-point piecewise-linear (LNR) transfer function programming and thermal output offset correction-confirmed by datasheet section 14.1.6 and option code definition.
Key Specifications

| Diagnostics | On-chip diagnostics including broken-track, VDD/VSS fault detection, and SENT frame CRC validation |
Pinout & Package
DMP-4 (Dual Mold Package) with 4-pin surface-mount configuration, optimized for direct module integration without PCB. Pin 1 and Pin 4 are both VSS (ground), with either usable for grounding; Pin 2 is VDD (supply); Pin 3 is OUT (SENT signal output).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | VSS (Ground) | Primary ground reference; electrically identical to Pin 4; one must be connected, the other left floating per datasheet guidance |
| Pin 2 | VDD | 4.5–5.5 V supply input with internal POR and voltage monitoring (MT4V/MT7V thresholds) |
| Pin 3 | OUT | SENT-compliant open-drain output delivering calibrated position data and diagnostic frames |
| Pin 4 | VSS (Ground) | Secondary ground terminal; functionally redundant with Pin 1 but required for mechanical stability in DMP-4 layout |
Key Features

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-258-RX | Lacks thermal output offset correction; same 17-point LNR programmability and SENT interface | Suitable where ambient temperature variation is limited (<85 °C max) or system-level compensation is implemented externally | Select when thermal drift budget allows omission of on-chip offset correction to reduce calibration complexity |
| MLX90367LGO-ADB-000-TU | Higher 14-bit resolution; SPI/I²C interface instead of SENT; no thermal offset correction; different DFN package | Preferred for non-automotive industrial systems requiring higher resolution and flexible digital interface, not SENT-based ECUs | Choose for SPI-based controllers needing finer position granularity, accepting trade-off of no SENT diagnostics and no thermal correction |
Compared with MLX90366LVS-AEU-258-RX, the AEV-258 variant omits thermal offset correction-reducing calibration overhead but limiting accuracy at temperature extremes-while the MLX90367 offers higher resolution and SPI flexibility at the cost of SENT compatibility and automotive qualification.

FAQ
What is the SENT protocol compliance level of the MLX90366LVS-AEU-258-RX?
The MLX90366LVS-AEU-258-RX implements SENT output fully compliant with SAE J2716-2010 Rev 3.0, supporting both Throttle Sensor and Secure Sensor frame formats. It delivers 12-bit position data in the fast channel with diagnostic codes, and enhanced serial messages-including user-defined values and error reporting-in the slow channel. Frame period is fixed at 882 μs, and timing parameters (rise/fall times, latency) meet automotive ECU interface requirements as verified in datasheet sections 7 and 13.
Does the MLX90366LVS-AEU-258-RX support thermal output offset correction?
Yes, the MLX90366LVS-AEU-258-RX explicitly includes thermal output offset correction, confirmed by its AEU option code (per datasheet Table 1 and section 14.1.6). This feature dynamically compensates for temperature-induced zero-point drift across −40 °C to +150 °C, maintaining ≤±0.3° angular error without external calibration. It is enabled by default and stored in EEPROM, distinguishing it from AEV or ADS variants which lack this capability.
What package type and pin configuration does the MLX90366LVS-AEU-258-RX use?
The MLX90366LVS-AEU-258-RX uses the DMP-4 (Dual Mold Package) with 4 surface-mount terminals: Pin 1 (VSS), Pin 2 (VDD), Pin 3 (OUT), and Pin 4 (VSS). Datasheet section 19.5 confirms this pinout and specifies STD4 2.54 trim-and-form configuration for the "-258" suffix. Either VSS pin may serve as ground reference, but one must remain floating to avoid ground loop issues-critical for noise immunity in automotive harness environments.
How is the transfer characteristic programmed on the MLX90366LVS-AEU-258-RX?
The MLX90366LVS-AEU-258-RX supports 17-point piecewise-linear (LNR) transfer function programming via its 128-byte EEPROM, as defined for AEU option codes in datasheet section 14.1.4. Users configure coordinate points (e.g., LNRAX–LNRCS) to map raw magnetic input to calibrated output, enabling precise linearization for custom mechanical travel. Programming is performed using Melexis' PTC software and standard SENT communication-no additional hardware interface required.
Is the MLX90366LVS-AEU-258-RX qualified for automotive applications?
Yes, the MLX90366LVS-AEU-258-RX is AEC-Q100 qualified for Grade 0 (−40 °C to +150 °C), with full test reports covering stress testing, reliability, and failure analysis. It meets automotive EMC requirements per ISO 11452 and ISO 7637, includes on-board diagnostics (broken-track, supply fault detection), and supports functional safety development per ISO 26262. These qualifications are documented in the official Melexis datasheet revision 002 (April 2019) and certified manufacturing records.
