Product details
Overview
MLX90366LVS-ADS-253-RE 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), delivering 12-bit resolution with 10-bit thermal accuracy, SENT output per SAE J2716-2010, and AEC-Q100 qualification for automotive pedal and steering wheel position sensing.
For engineers reviewing the MLX90366LVS-ADS-253-RE datasheet, pinout, applications, or equivalent options, this page provides verified technical context, pin-level design meaning, real-world application cards, and validated alternative options for non-contacting position sensing in harsh-temperature environments.
Technical Context
The MLX90366LVS-ADS-253-RE integrates a 16-bit RISC DSP core running at 10 MHz (2.5 MIPS), performs real-time field vector decomposition using CoRDiC algorithms, and supports user-programmable 17-point piecewise-linear transfer characteristics. Its on-chip IMC structure enables precise 3-axis magnetic field sensing without external concentrators.
It implements SENT protocol with Throttle Sensor Format frames, delivers diagnostic reporting via fast channel (including broken-track, overvoltage, and under-voltage detection), and features built-in thermal offset correction logic-specifically enabled in ADS-xxx variants per datasheet section 14.1.4 and Table 12.

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-253-RE | Same DMP-4 package and 17-pt LNR capability, but lacks thermal offset correction (per datasheet Table 12 and section 14.1.6) | Suitable where ambient temperature variation is limited (<50°C swing) or system-level software compensation is implemented | Select AEV-253 only if thermal drift budget allows >±90 LSB15 offset drift over −40°C to +150°C |
| MLX90366LVS-AEX-253-RE | Includes thermal output offset correction *and* enhanced EEPROM lock features (MEMLOCK=2), not present in ADS-253 | Better suited for production environments requiring write-protection of calibration data post-EOL programming | Choose AEX-253 when firmware update security and calibration integrity are mandatory-adds no latency or accuracy trade-off |
Compared with MLX90366LVS-ADS-253-RE, AEV-253 omits thermal offset correction-increasing zero-point drift risk in wide-temperature applications-while AEX-253 adds EEPROM locking without affecting timing or resolution, making it ideal for high-integrity production lines.

FAQ
What is the SENT frame structure used by MLX90366LVS-ADS-253-RE?
The MLX90366LVS-ADS-253-RE uses the Throttle Sensor Format defined in SAE J2716-2010, transmitting 12-bit position data plus 4-bit CRC in each frame. Frame period is fixed at 882 μs, with optional pause pulses and diagnostic reporting embedded in the fast channel per datasheet section 13.2.
Does MLX90366LVS-ADS-253-RE require an external microcontroller to configure its 17-point LNR curve?
No-MLX90366LVS-ADS-253-RE supports full end-user programming via SENT interface using Melexis' PTM software and compatible programmers. All 17-point LNR parameters, clamping limits, and diagnostic settings are written to internal 128 B EEPROM without external MCU involvement.
How does the thermal offset correction in MLX90366LVS-ADS-253-RE differ from standard MLX90366 variants?
MLX90366LVS-ADS-253-RE implements on-chip thermal offset correction logic per datasheet section 14.1.6, actively compensating for temperature-induced zero-point drift. This feature is absent in AxU-xxx and AEV-xxx variants and is exclusive to ADS-xxx and AxX-xxx option codes.
Can MLX90366LVS-ADS-253-RE operate without a printed circuit board?
Yes-MLX90366LVS-ADS-253-RE is designed for No-PCB module integration per datasheet description. Its DMP-4 package supports direct wire bonding to connectors or housings, eliminating PCB-related failure modes while maintaining full electrical and thermal specifications.
What is the maximum magnetic field strength MLX90366LVS-ADS-253-RE can tolerate without saturation?
MLX90366LVS-ADS-253-RE tolerates up to ±1 T magnetic flux density per absolute maximum ratings. However, for optimal linearity, BX/BY should remain ≤70 mT (beyond which IMC® saturation increases error) and total field norm √[BX²+BY²+(BZ/1.2)²] must exceed 20 mT for reliable operation.
