Product details
Overview
MLX90366LVS-AEX-253-RX from Melexis is a Triaxis® absolute rotary and linear position sensor IC based on Hall-effect technology with integrated magneto-concentrator (IMC®), delivering 12-bit resolution, SENT output per SAE J2716-2010, and AEC-Q100 qualification for automotive pedal and steering wheel position sensing.
For engineers reviewing the MLX90366LVS-AEX-253-RX datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SENT timing compliance, thermal offset correction capability, DMP-4 package mapping, and validated automotive-grade alternatives for throttle and ride height sensor designs.
Technical Context
The MLX90366LVS-AEX-253-RX measures all three orthogonal magnetic field components (Bx, By, Bz) to compute absolute angular or linear position via CoRDiC-based coordinate rotation. Its DSP performs real-time angle calculation at 441 µs internal measurement period with configurable FIR filtering (FILTER = 0/1/2).
It implements SENT protocol in Throttle Sensor format with dual-channel diagnostics: fast channel reports error codes and user-defined values, while slow channel delivers enhanced serial messages including 48-bit ID, OEM data fields, and diagnostic status. Thermal Output Offset correction is enabled per the AEX option code.

FAQ
What is the SENT frame period and timing compliance of the MLX90366LVS-AEX-253-RX?
The MLX90366LVS-AEX-253-RX outputs SENT frames every 882 µs, fully compliant with SAE J2716-2010. It supports Throttle Sensor format with fast-channel diagnostics and configurable slow-channel OEM data. Rise/fall times are 2.97–5.31 µs (cable) and 4.84–6.84 µs (receiver), meeting automotive EMI requirements without external buffering.
Does the MLX90366LVS-AEX-253-RX support thermal compensation for position output drift?
Yes, the AEX option code explicitly enables Thermal Output Offset correction, reducing angular error drift to ±60 LSB15 over −40°C to +125°C. This feature is factory-configured and user-programmable via EEPROM, distinguishing MLX90366LVS-AEX-253-RX from ADU/AEV variants lacking this correction.
What package type and pin configuration does the MLX90366LVS-AEX-253-RX use?
The MLX90366LVS-AEX-253-RX uses the DMP-4 (Dual Mold Package) with 4 leads, STD2 2.54 mm pitch, and face-down reel packaging (RX suffix). Pinout is fixed: Pin 1 (VSS), Pin 2 (VDD), Pin 3 (OUT), Pin 4 (VSS), with either VSS pin usable for grounding-though Pin 1 must remain floating if unused.
How does the MLX90366LVS-AEX-253-RX achieve absolute position sensing without a rotating magnet alignment constraint?
The MLX90366LVS-AEX-253-RX leverages Triaxis® technology to measure all three orthogonal magnetic field components (Bx, By, Bz) simultaneously. Using on-chip CoRDiC computation, it decodes absolute angle or linear displacement from any moving magnet orientation-enabling flexible mechanical designs such as off-axis rotary or axial linear configurations without strict magnet alignment.
Is the MLX90366LVS-AEX-253-RX qualified for automotive safety-critical applications?
Yes, the MLX90366LVS-AEX-253-RX is AEC-Q100 qualified to Grade 0 (−40°C to +150°C) and includes built-in diagnostics: broken track detection, supply rail monitoring, SENT CRC validation, and thermal error reporting. While not ASIL-certified itself, it serves as a foundational sensor in ASIL-B systems when combined with appropriate system-level fault handling-verified in production pedal and steering applications.
