Product details

Overview

MLX90366LVS-AEU-253-RE 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 and steering wheel position sensing.

For engineers reviewing the MLX90366LVS-AEU-253-RE datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, SENT timing compliance, thermal offset correction capability, programmable multi-point transfer characteristic, and DMP-4 package integration details critical for automotive sensor module design.

Technical Context

The MLX90366LVS-AEU-253-RE integrates a 16-bit RISC DSP core running at 10 MHz (2.5 MIPS), processes orthogonal Bx/By/Bz magnetic field components via IMC-enhanced front-end, and computes absolute angular or linear position using CoRDiC-based rectangular-to-polar transformation.

It implements SENT protocol with Throttle Sensor Format or Secure Sensor Format frames, supports user-programmable 17-point piecewise-linear transfer characteristic (AEU option), and includes on-chip diagnostics for broken track, overvoltage, undervoltage, and thermal offset drift compensation-enabling robust non-contacting potentiometer replacement in harsh environments.

Key Specifications

Parameter	Value and Actual Design Meaning

Programmability	End-user configurable 17-point LNR transfer curve, clamping thresholds, sensitivity mismatch (SMISM/K), and thermal offset correction (enabled in AEU-xxx).

Pinout & Package

DMP-4 (Dual Mold Package) with 4-pin leadframe, STD2 2.54 mm pitch, face-up reel packaging (RE), RoHS-compliant, designed for direct module integration without PCB.

Pin/Terminal	Circuit Role	Design Meaning
1	VSS (Ground)	Primary ground reference; either VSS pin may be used, but Pin 1 must remain floating if Pin 4 is used for grounding.
2	VDD	Power supply input (4.5–5.5 V); includes overvoltage protection up to +24 V and reverse voltage tolerance to −12 V.
3	OUT	SENT serial output signal; push-pull driver capable of driving 1 kΩ pull-down or 10 kΩ pull-up loads; supports diagnostic flag encoding.

FAQ

What is the SENT frame structure used by the MLX90366LVS-AEU-253-RE?

The MLX90366LVS-AEU-253-RE transmits SENT frames per SAE J2716-2010, supporting both Throttle Sensor Format (single fast channel) and Secure Sensor Format (fast + slow channels). Each frame contains 12-bit position data, CRC, status bits, and diagnostic flags. Frame period is fixed at 882 μs, with sync pulse latency of 1084 μs for first measurement.

Does the MLX90366LVS-AEU-253-RE support programmable linearization?

Yes, the MLX90366LVS-AEU-253-RE supports end-user programmable 17-point piecewise-linear (LNR) transfer characteristics via EEPROM. This allows precise calibration to custom mechanical profiles-such as non-uniform rotary cams or asymmetric linear strokes-without external microcontroller intervention.

How does thermal output offset correction work in the MLX90366LVS-AEU-253-RE?

The MLX90366LVS-AEU-253-RE implements on-chip thermal output offset correction by measuring die temperature and applying real-time compensation to the raw angle output. This feature reduces thermal drift to ±90 LSB15 (≈±0.45°) over −40°C to +150°C, significantly improving long-term accuracy in engine bay or transmission applications.

What is the magnetic field range supported by the MLX90366LVS-AEU-253-RE?

The MLX90366LVS-AEU-253-RE supports magnetic flux densities up to 70 mT in Bx/By and 126 mT in Bz. Its integrated magneto-concentrator (IMC®) enhances sensitivity while maintaining linearity; operation below 20 mT degrades SNR, and above 70 mT risks IMC saturation and increased linearity error.

Is the MLX90366LVS-AEU-253-RE pin-compatible with other MLX90366 variants?

Yes, all MLX90366 DMP-4 variants-including MLX90366LVS-AEU-253-RE, MLX90366LVS-AEV-253-RE, and MLX90366LVS-AEX-253-RE-share identical 4-pin DMP-4 package, pinout, and electrical interface. Functional differences (e.g., thermal correction, EEPROM endurance) are software-configurable and do not affect hardware compatibility.
