Product details
Overview
MLX90366LVS-AEV-258-RE 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 (Throttle format), and operates across −40 °C to +150 °C. It enables non-contact rotary and linear position sensing in automotive pedal and steering wheel applications.
For engineers reviewing the MLX90366LVS-AEV-258-RE 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 automotive-grade alternatives for throttle, pedal, and ride height sensing designs.
Technical Context
The MLX90366LVS-AEV-258-RE integrates a 16-bit RISC DSP core running at 10 MHz (2.5 MIPS) and performs real-time coordinate rotation (CoRDiC) to compute angular position from orthogonal magnetic field vectors. Its internal IMC structure provides calibrated gain of 1.2–1.8× in XY and 1.1–1.3× in Z, with k-factor trimming (1.0–1.5) for axis sensitivity matching.
It implements SENT frame transmission with 882 μs period, supports programmable 17-point piecewise-linear transfer characteristics, and includes on-chip diagnostics for broken track, over/under-voltage, and thermal offset correction-enabled specifically in AEV-xxx variants per datasheet Section 14.1.6.

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-AEU-258-RE | Lacks thermal output offset correction; uses same 17-point LNR but no BZ-axis thermal drift compensation | Suitable for less thermally demanding linear applications where zero-point stability below −20 °C is not critical | Select when cost optimization is prioritized and thermal drift within ±90 LSB15 (±0.45°) is acceptable |
| MLX90366LVS-AEX-258-RE | Includes thermal output offset correction and enhanced EEPROM endurance; identical pinout and SENT protocol | Preferred for next-generation modules requiring extended lifecycle (>100k write cycles) and tighter thermal zero drift specs | Choose for new designs targeting >15-year field life and full AEC-Q100 requalification scope |
Compared with MLX90366LVS-AEV-258-RE, the AEU-258-RE omits thermal offset correction-reducing zero-point stability at extremes-while the AEX-258-RE adds EEPROM endurance and retains all AEV features, making it the long-term upgrade path for high-reliability automotive modules.

FAQ
What is the SENT frame structure used by MLX90366LVS-AEV-258-RE?
The MLX90366LVS-AEV-258-RE implements the SAE J2716-2010 Throttle position format: 882 μs frame period, 4-nibble data payload (12-bit angle + 4-bit CRC), sync pulse, and optional pause pulses. Diagnostic flags and OEM-defined values are transmitted via the fast channel, with error codes encoded per Section 13.2.2 of the datasheet.
Does MLX90366LVS-AEV-258-RE support thermal output offset correction?
Yes, MLX90366LVS-AEV-258-RE explicitly supports thermal output offset correction as confirmed in datasheet Section 14.1.6 and Option Code definition (AEV = Standard version with 17-Pts LNR Parameters). This feature compensates for temperature-induced zero-point drift in Bx/By measurements across −40 °C to +150 °C.
What package type and dimensions does MLX90366LVS-AEV-258-RE use?
MLX90366LVS-AEV-258-RE uses the DMP-4 package in STD4 2.54 mm pitch configuration (datasheet Section 19.4), with outline dimensions of 3.0 × 3.0 × 0.9 mm, 4-pin leadframe, and RoHS-compliant matte tin plating. It supports no-PCB module integration per Section 1.
How is the 17-point transfer characteristic programmed in MLX90366LVS-AEV-258-RE?
The 17-point piecewise-linear (LNR) transfer curve in MLX90366LVS-AEV-258-RE is programmed via I²C or SENT-based EEPROM writes to dedicated LNRAX–LNRCS registers (Section 12, Table on p.15–16). Each point defines X/Y/S coordinates for slope, intercept, and saturation-enabling end-user calibration to mechanical nonlinearity without firmware changes.
What diagnostic capabilities does MLX90366LVS-AEV-258-RE provide?
MLX90366LVS-AEV-258-RE provides on-chip diagnostics including broken VSS/VDD detection (BVSSPD/BVDDPU), over/under-voltage flags (MT4V/MT7V), SENT frame CRC errors, and thermal offset saturation alerts-all reported via the SENT fast channel per Section 13.2.2 and Table on p.8.
