Product details
Overview
MLX90366LVS-AEV-258-SP from Melexis is a Triaxis® monolithic Hall-effect position sensor IC that measures absolute rotary or linear position by decoding orthogonal (Bx, By) and parallel (Bz) magnetic flux components. 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 pedal and steering wheel position sensing.
For engineers reviewing the MLX90366LVS-AEV-258-SP datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SENT protocol timing, thermal offset correction capability, DMP-4 package mapping, and validated alternative options for AEC-Q100-compliant non-contacting position sensing designs.
Technical Context
The MLX90366LVS-AEV-258-SP integrates a 16-bit RISC DSP core running at 10 MHz (2.5 MIPS), performing real-time CoRDiC-based rectangular-to-polar conversion of Bx/By/Bz inputs to compute absolute angle or linear displacement. Its SENT output supports Throttle Position and Secure Sensor formats with fast-channel diagnostic reporting and slow-channel enhanced serial messages.
It features user-programmable 17-point piecewise-linear transfer characteristics (AEV option), thermal output offset correction, integrated IMC® magneto-concentrator with k-factor trimming (1.0–1.5), and factory-trimmed intrinsic linearity error of ±1° (XY axis) and ±2.5° (XZ/YZ axes).

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-AEV-258-SP | Same DMP-4 package and AEV-258 option code; adds dual-die redundancy and independent SENT outputs for ASIL-D systems | Required for fault-tolerant applications demanding dual-channel independence and lockstep comparison | Select when functional safety integrity level exceeds ASIL-B or dual-output redundancy is mandated |
| MLX90393ELH-ABA-000-TU | Triaxis® 3-axis magnetic sensor with I²C/SPI interface; no SENT output; 16-bit resolution; wider magnetic range (±50 mT per axis) | Suitable for industrial position feedback where digital bus communication replaces SENT, and higher resolution is prioritized over automotive diagnostics | Choose for non-automotive applications needing flexible host interface and lower power (2.5 µA standby), not SENT compliance |
Compared with MLX90366LVS-AEV-258-SP, MLX90367LVS-AEV-258-SP adds hardware-level redundancy for ASIL-D, while MLX90393ELH-ABA-000-TU trades SENT diagnostics for I²C flexibility and lower quiescent current-neither is pin-compatible, but both address adjacent design requirements in position sensing.

FAQ
What is the SENT protocol configuration supported by MLX90366LVS-AEV-258-SP?
The MLX90366LVS-AEV-258-SP implements SENT per SAE J2716-2010 with Throttle Position and Secure Sensor formats. It delivers fast-channel diagnostic reporting and slow-channel enhanced serial messages containing user-defined values, error codes, and 48-bit ID. Frame period is fixed at 882 μs, and the device supports pause pulses and configurable CRC standards (2007 or 2010).
Does MLX90366LVS-AEV-258-SP support thermal compensation of output offset?
Yes, MLX90366LVS-AEV-258-SP includes thermal output offset correction, a feature enabled in the AEV and AxX option codes. This function dynamically compensates for temperature-induced zero-point drift, maintaining angular accuracy within ±0.3° over −40 °C to +150 °C in rotary applications-critical for throttle and pedal sensors where null stability is essential.
What package type and pin configuration does MLX90366LVS-AEV-258-SP use?
MLX90366LVS-AEV-258-SP uses the DMP-4 (Dual Mold Package) with 4 terminals in STD4 2.54 mm pitch. Pinout is VSS (1), VDD (2), OUT (3), VSS (4). Either VSS pin may serve as ground, but pin 1 must remain unconnected if pin 4 is used-this dual-ground design enhances noise immunity and simplifies no-PCB module integration.
How is the 17-point transfer characteristic programmed in MLX90366LVS-AEV-258-SP?
The 17-point piecewise-linear transfer curve in MLX90366LVS-AEV-258-SP is programmed via EEPROM using Melexis' PTM (Programmable Transfer Matrix) tool. Parameters include LNRAX–LNRCS coordinates, CLAMPLOW/CLAMPHIGH limits, DP (discontinuity point), and CW (clockwise direction flag). Programming occurs during end-of-line calibration and persists through power cycles without external memory.
What diagnostic capabilities does MLX90366LVS-AEV-258-SP provide?
MLX90366LVS-AEV-258-SP provides comprehensive on-chip diagnostics: broken VDD/VSS track detection, overvoltage/undervoltage monitoring, SENT CRC error reporting, internal watchdog timeout, and field-sensing validity checks. Diagnostic status is reported in real time via the SENT fast channel, enabling immediate system-level fault response without host processor intervention.
