Melexis Technologies NV MLX90364LVS-AEE-208-RE

Overview

MLX90364LVS-AEE-208-RE from Melexis is an automotive-grade Triaxis® absolute rotary and linear position sensor IC in DMP-4 package, delivering 12-bit analog or PWM output with ±0.3° magnetic angle phase error (XY axis), 10-bit thermal accuracy, and integrated diagnostics including open/short detection and over-voltage protection. It operates across −40 °C to +150 °C and is used in throttle, EGR valve, and turbo actuator position sensing.

For engineers reviewing the MLX90364LVS-AEE-208-RE datasheet, pinout, applications, or equivalent options, key selection considerations include its programmable transfer characteristic (4- or 17-point piecewise-linear), thermal offset correction capability (AEE variant), dual-ground-pin DMP-4 package for EMC robustness, and AEC-Q100 qualification for safety-critical automotive subsystems.

Technical Context

The MLX90364LVS-AEE-208-RE implements Triaxis® Hall technology to measure all three orthogonal magnetic field components (B_X, B_Y, B_Z) using on-die IMC structures, enabling absolute angular or linear position decoding without external PCB. Its embedded DSP performs real-time coordinate rotation (CoRDiC) and multi-point linearization.

It features a 12.6–14 MHz main clock with ±3% thermal drift, configurable FIR filtering (Filter=0/1/2), and dual-output architecture supporting ratiometric analog (0–100% V_DD) or programmable PWM (100–1000 Hz). The AEE variant includes thermal output offset correction, distinguishing it from AED versions.

FAQ

What is the primary sensing principle used in the MLX90364LVS-AEE-208-RE?

The MLX90364LVS-AEE-208-RE uses Triaxis® Hall technology to detect all three orthogonal components (B_X, B_Y, B_Z) of a magnetic field. This enables computation of absolute angular position (0–360°) or linear displacement via on-die CoRDiC processing. Unlike single-axis Hall sensors, it does not require external magnets oriented perpendicularly - the DMP-4 package integrates the sensing die with optimized magnetic flux path geometry.

Does the MLX90364LVS-AEE-208-RE require an external microcontroller to operate?

No, the MLX90364LVS-AEE-208-RE contains an embedded RISC microcontroller, EEPROM, RAM, and firmware that fully manage signal acquisition, processing, diagnostics, and output generation. It operates autonomously after initial programming - no host MCU is needed for basic position reporting. Configuration (e.g., output mode, transfer curve) is performed once via I²C-compatible interface during manufacturing.

How does the thermal offset correction in the AEE variant improve performance?

The AEE variant of MLX90364LVS-AEE-208-RE implements on-chip thermal output offset correction, reducing zero-point drift caused by temperature gradients across the die. This feature lowers total angular error by up to ±0.5° over −40 °C to +150 °C compared to non-AEE versions, which is critical for applications like throttle position where idle stability and transient accuracy depend on consistent baseline output.

What are the key EMC advantages of the DMP-4 package used in MLX90364LVS-AEE-208-RE?

The DMP-4 package integrates up to four decoupling capacitors directly into the mold compound, eliminating discrete bypass components and minimizing PCB loop area. This achieves superior ESD immunity (IEC 61000-4-2 Level 4) and radiated emissions suppression - verified per AEC-Q200 - without requiring additional layout space or component placement, making MLX90364LVS-AEE-208-RE ideal for compact, high-density automotive modules.

Can the MLX90364LVS-AEE-208-RE be programmed in-system after soldering?

Yes, the MLX90364LVS-AEE-208-RE supports in-system programming via its dedicated programming interface (compatible with Melexis' PTM tooling), allowing full configuration - including output mode (analog/PWM), transfer characteristic, diagnostics, and lock status - after mounting on the final module. This enables late-stage customization and field updates without redesigning the sensor subassembly.
