Product details

Overview

MLX90366LVS-ADU-253-RE from Melexis is an AEC-Q100 qualified Triaxis® absolute rotary and linear position sensor IC using Hall-effect 3D magnetic field sensing (Bx, By, Bz) with SENT output per SAE J2716-2010, 12-bit resolution, 10-bit thermal accuracy, and programmable piecewise-linear transfer characteristic. It operates across −40 °C to +150 °C and enables non-contacting potentiometer replacement in automotive throttle and steering systems.

For engineers reviewing the MLX90366LVS-ADU-253-RE datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, SENT timing compliance, thermal offset correction capability, DMP-4 package mapping, and validated automotive-grade alternatives for pedal, float-level, and ride height sensing designs.

Technical Context

The MLX90366LVS-ADU-253-RE integrates a 16-bit RISC DSP core running at 10 MHz (2.5 MIPS), performs real-time coordinate rotation (CoRDiC) on raw sine/cosine ADC outputs, and computes absolute angular or linear position from orthogonal and parallel magnetic flux components. Its internal IMC structure provides calibrated gain of 1.2–1.8× in XY and 1.1–1.3× in Z.

It implements SENT protocol with Throttle Sensor Format frames (294 ticks/frame, 882 µs period), supports diagnostic reporting via fast channel, and includes configurable FIR filtering (FILTER=0/1/2), clamping, discontinuity point definition, and thermal output offset correction - enabled specifically in ADU-xxx variants per datasheet Section 14.1.6.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Interface	SENT per SAE J2716-2010 (Throttle Sensor Format); enables deterministic, noise-immune digital transmission over long cables in EMI-heavy automotive environments.
Resolution & Accuracy	12-bit position resolution with 10-bit thermal accuracy; delivers ≤ ±0.3° angular error over −40 °C to +125 °C when k = 1, validated for high-stability rotary applications.
Operating Range	−40 °C to +150 °C ambient; AEC-Q100 Grade 0 qualified for under-hood and transmission-mounted position sensing.
Magnetic Sensing	Triaxis® 3D Hall sensing (Bx, By, Bz); supports absolute angle measurement up to 360° or linear stroke via custom magnetic circuit design.
Supply & Protection	4.5–5.5 V nominal supply; integrated over-voltage protection (24 V), under-voltage detection (MT4V threshold at 4.0 V), and short-circuit robustness (18 mA sink/source).
Programmability	User-configurable 17-point piecewise-linear transfer curve (ADU-253 variant), thermal output offset correction, diagnostics enablement, and EEPROM-stored 48-bit ID.

Pinout & Package

DMP-4 (Dual Mold Package) with 4-pin leadframe, STD2 2.54 mm pitch, RoHS-compliant, no PCB required for module integration. Pin 1 and Pin 4 are both VSS (ground); Pin 2 is VDD (supply); Pin 3 is OUT (SENT output). Either VSS pin may be used for grounding, but Pin 1 must remain floating if Pin 4 is connected.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	VSS (Ground)	Secondary ground terminal; must remain floating if Pin 4 is used for grounding - avoids ground loop and ensures proper biasing of internal diagnostics.
Pin 2	VDD	Primary power input (4.5–5.5 V); powers analog front-end, DSP, SENT driver, and EEPROM; includes POR and MT4V startup detection.
Pin 3	OUT	SENT-compliant open-drain output (pull-up required); transmits encoded position, diagnostics, and OEM data in standardized nibble format.
Pin 4	VSS (Ground)	Primary ground terminal; mandatory connection point for return path, diagnostic reference, and thermal stability in high-temp operation.

Key Features

Feature	Design Value
Triaxis® 3D Magnetic Sensing	Simultaneous Bx, By, Bz measurement enables single-chip absolute angle or linear position decoding without external magnets or complex mechanical coupling.
SENT Output Compliance	Fully compliant with SAE J2716-2010 Throttle Sensor Format (294-tick frame, 882 µs period), supporting robust EMI-resistant communication in automotive networks.
17-Point Programmable Transfer Curve	End-user configurable LNR parameters allow precise calibration to mechanical nonlinearity (e.g., pedal travel arc or float arm geometry) without hardware redesign.
On-Chip Thermal Offset Correction	Compensates output drift over temperature using factory-trimmed coefficients - active in ADU-xxx variants and critical for <±0.3° angular stability across full automotive range.
No-PCB Module Integration	DMP-4 package allows direct wire-bonding to leads or flex substrates, eliminating PCB-related failure modes and improving mechanical robustness in vibration-prone applications.

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 SENT interface; uses 17-pt LNR without thermal offset correction (no AxX-xxx firmware).	Suitable for ambient-controlled cabin applications where thermal drift <±0.5° is acceptable.	Select when cost sensitivity outweighs under-hood thermal stability requirements.
MLX90366LVS-AEX-253-RE	Identical pinout and electrical specs; adds EEPROM lock (MEMLOCK) and enhanced serial message support beyond standard SENT throttle format.	Preferred for OEMs requiring traceable, write-protected calibration and extended OEM-specific diagnostics.	Choose when production-line programming security and multi-message SENT capability are mandatory.

Compared with MLX90366LVS-ADU-253-RE, the AEV-253 variant omits thermal offset correction - reducing accuracy at temperature extremes - while the AEX-253 adds EEPROM locking and extended serial messaging, increasing firmware complexity but enabling secure, multi-parameter system integration.

FAQ

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

The MLX90366LVS-ADU-253-RE implements the SAE J2716-2010 Throttle Sensor Format with a fixed 294-tick frame period (882 µs), delivering 12-bit position data plus diagnostic flags in the fast channel. Each frame includes synchronization pulses, nibble-aligned payload, and CRC-checked status bits - fully compatible with standard automotive SENT receivers.

Does MLX90366LVS-ADU-253-RE support thermal output offset correction?

Yes, MLX90366LVS-ADU-253-RE supports thermal output offset correction as specified in datasheet Section 14.1.6 for AxX-xxx variants. This feature actively compensates for temperature-induced zero-point drift using factory-trimmed coefficients stored in EEPROM, ensuring <±0.3° angular error over −40 °C to +125 °C.

What package type and pin configuration does MLX90366LVS-ADU-253-RE use?

MLX90366LVS-ADU-253-RE uses the DMP-4 package (STD2 2.54 mm pitch) with four terminals: Pin 1 (VSS, floating), Pin 2 (VDD), Pin 3 (OUT), and Pin 4 (VSS, primary ground). The dual-ground layout supports robust diagnostics and eliminates reliance on PCB routing for signal integrity.

How is the 17-point transfer characteristic programmed in MLX90366LVS-ADU-253-RE?

The 17-point piecewise-linear (LNR) transfer curve in MLX90366LVS-ADU-253-RE is programmed via I²C or SENT-compatible host interface into dedicated EEPROM registers (LNRAX–LNRCS). Configuration requires Melexis' PTM software and supports end-of-line calibration to match mechanical travel profiles such as pedal arcs or float arm motion.

Is MLX90366LVS-ADU-253-RE qualified for automotive safety-critical systems?

Yes, MLX90366LVS-ADU-253-RE is AEC-Q100 Grade 0 qualified (−40 °C to +150 °C) and integrates multiple diagnostics - broken VDD/VSS detection, SENT CRC validation, watchdog timer, and thermal monitoring - enabling ASIL-B compliance when implemented per ISO 26262 system architecture requirements.
