Product details
Overview
MLX90366LVS-AEV-250-RX from Melexis is a Triaxis® absolute rotary and linear position sensor IC based on Hall-effect technology with SENT output (SAE J2716-2010), 12-bit resolution, 10-bit thermal accuracy, and AEC-Q100 qualification for automotive use in throttle, pedal, and steering wheel position sensing.
For engineers reviewing the MLX90366LVS-AEV-250-RX datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, real-world design meaning of key specs, validated pin functions, automotive-grade diagnostics, and confirmed alternative options for position-sensing system design.
Technical Context
The MLX90366LVS-AEV-250-RX integrates a 16-bit RISC DSP core running at 10 MHz (2.5 MIPS) to compute absolute angular or linear position from orthogonal Bx, By, and Bz magnetic field components. It implements CoRDiC-based rectangular-to-polar conversion and supports user-programmable 17-point piecewise-linear transfer characteristics.
Its SENT interface delivers Throttle Position or Secure Sensor format frames with embedded diagnostics, error codes, and OEM-defined serial messages. The device features on-chip IMC gain calibration (k-factor = 1–1.5), thermal offset correction (enabled in AEV variant), and dual VSS pins for robust grounding in noisy automotive environments.

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-RX | Same DMP-4 package and AEV option code; differs only in trim-and-form configuration (STD2 2.54 mm vs. STD1 1.27 mm lead pitch) | Identical functional performance; requires PCB layout revision for lead spacing | Select when board-level mechanical constraints favor wider pitch or legacy tooling compatibility |
| MLX90366LVS-AEV-258-RX | Same AEV functionality; uses STD4 2.54 mm trim-and-form with different sensitive spot positioning per package outline | Same automotive temperature and accuracy specs; magnet placement geometry differs per mechanical mounting requirement | Choose for applications requiring alternate magnet alignment or housing integration per Melexis POD STD4 drawing |
Compared with MLX90366LVS-AEV-250-RX, the -253-RX and -258-RX variants retain identical electrical performance, SENT protocol behavior, and thermal offset correction-but differ strictly in mechanical packaging dimensions and leadform, necessitating layout or fixture updates without functional trade-offs.

FAQ
What is the SENT frame structure used by the MLX90366LVS-AEV-250-RX?
The MLX90366LVS-AEV-250-RX transmits SENT frames compliant with SAE J2716-2010, using either Throttle Position or Secure Sensor format. Each frame is 882 µs long and contains 12 nibbles: 4 for position data (12-bit resolution), 2 for CRC, and 6 for diagnostics or OEM-defined values. The device supports both fast-channel (position + errors) and slow-channel (enhanced serial messages) transmission modes, with configurable pause pulses between frames.
Does the MLX90366LVS-AEV-250-RX support thermal offset correction?
Yes, the MLX90366LVS-AEV-250-RX includes thermal output offset correction as part of its AEV option code. This feature actively compensates for temperature-induced DC offset drift at the DSP input stage, reducing angular error to ±60 LSB15 over −40°C to +125°C-verified in the device's accuracy specification table and enabled by default in factory programming.
How does the MLX90366LVS-AEV-250-RX achieve absolute position sensing without a PCB?
The MLX90366LVS-AEV-250-RX uses the DMP-4 package with built-in capacitors and optimized leadframe design to enable "NoPCB" module integration. Its internal decoupling capacitance (per Section 16 of the datasheet) and robust DMP-4 molding eliminate the need for an external PCB, allowing direct mounting onto metal housings or plastic carriers-improving mechanical durability and environmental resistance in harsh automotive environments.
What magnetic field strength is required for reliable operation of the MLX90366LVS-AEV-250-RX?
The MLX90366LVS-AEV-250-RX requires a minimum magnetic flux norm of 20 mT (√[Bx² + By² + (Bz/1.2)²]) for optimal signal-to-noise ratio. For XY-plane sensing, BX and BY must each exceed 70 mT (with saturation onset above that level), and BZ must reach at least 126 mT. These thresholds are specified in the magnetic section of the datasheet and ensure ≤0.2° peak-to-peak noise under recommended filter settings.
Can the MLX90366LVS-AEV-250-RX be reprogrammed in-system for custom transfer curves?
Yes, the MLX90366LVS-AEV-250-RX supports in-system programming of its 17-point piecewise-linear transfer characteristic via SENT interface using Melexis' standard protocol. End users can write LNRAX–LNRCS parameters (Section 14.1.4), clamping limits, filter settings, and diagnostic configurations into EEPROM-enabling field calibration for application-specific linearity targets without hardware changes.
