Product details

Overview

MLX90366LVS-AEX-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 integrated diagnostics. It operates across −40 °C to +150 °C, is AEC-Q100 qualified, and supports programmable multi-point transfer characteristics for automotive pedal, steering, and throttle position sensing.

For engineers reviewing the MLX90366LVS-AEX-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 robust sensor system design.

Technical Context

The MLX90366LVS-AEX-253-RE integrates a 16-bit RISC DSP core running at 10 MHz (2.5 MIPS), processes B_x, B_y, and B_z magnetic field components simultaneously, and computes absolute angular or linear position using CoRDiC-based rectangular-to-polar conversion. Its IMC-enhanced sensitivity achieves ±126 mT B_z tolerance and 70 mT B_x/B_y minimum field detection.

This variant implements Thermal Output Offset correction (enabled by AxX option code), uses FILTER = 1 for optimal latency/noise trade-off (1745 μs average field-to-SENT latency), and delivers SENT frames in Throttle Sensor format with diagnostic reporting via fast channel and enhanced serial messages via slow channel.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MLX90367LVS-AEX-253-RE	Same DMP-4 package, SENT interface, and AxX thermal offset correction; adds dual-die redundancy for ASIL-B compliance	Required where functional safety mandates dual-channel monitoring (e.g., steering angle in L2+ ADAS)	Select MLX90367LVS-AEX-253-RE only when ISO 26262 ASIL-B certification is mandatory; otherwise MLX90366LVS-AEX-253-RE suffices
TLV493DW2B6HXTSA1	3D Hall sensor with I²C output (not SENT); 12-bit resolution; no built-in thermal offset correction or programmable LNR	Suitable for cost-sensitive industrial position feedback where SENT is not mandated and diagnostics are handled externally	Choose TLV493DW2B6HXTSA1 only for non-automotive designs lacking SENT infrastructure and requiring simpler I²C integration

Compared with MLX90367LVS-AEX-253-RE, the MLX90366LVS-AEX-253-RE provides identical core sensing and SENT functionality at lower cost and complexity, while TLV493DW2B6HXTSA1 offers I²C convenience but lacks automotive diagnostics, thermal correction, and SENT protocol compliance required for Tier-1 vehicle systems.

FAQ

What is the SENT protocol compliance level of MLX90366LVS-AEX-253-RE?

The MLX90366LVS-AEX-253-RE implements SENT output fully compliant with SAE J2716-2010, supporting both Throttle Sensor format and Secure Sensor format. It delivers 12-bit position data in the fast channel with diagnostic flags, and extended OEM data (e.g., serial ID, temperature) via the slow channel. Frame timing, tick count (294 ticks), and pause pulse behavior match the standard's requirements for automotive ECU interoperability.

Does MLX90366LVS-AEX-253-RE support thermal offset correction, and how is it activated?

Yes, MLX90366LVS-AEX-253-RE supports Thermal Output Offset correction - a feature exclusive to AxX option-code variants. It is factory-enabled and operates automatically during operation; no end-user programming is required. The correction reduces zero-point drift to ±60 LSB₁₅ over −40 °C to +125 °C, translating to <±0.3° angular error in rotary applications when k = 1.

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

MLX90366LVS-AEX-253-RE uses the DMP-4 (Dual Mold Package) with 4 terminals in STD2 2.54 mm pitch. Pins are: 1=VSS (to be left floating), 2=VDD, 3=OUT (SENT signal), 4=VSS (functional ground). This leadframe-only construction enables direct magnet coupling and eliminates the need for a PCB substrate in sensor modules.

How does the MLX90366LVS-AEX-253-RE achieve absolute position sensing without a dedicated reference point?

The MLX90366LVS-AEX-253-RE achieves absolute position by measuring all three orthogonal magnetic field components (B_x, B_y, B_z) simultaneously using its Triaxis® architecture and computing angle via CoRDiC-based arctangent. With proper magnet placement (e.g., diametrically magnetized ring for rotary, moving dipole for linear), it decodes position continuously from 0° to 360° or full stroke - no homing or index pulse required.

Is MLX90366LVS-AEX-253-RE qualified for automotive use, and what certifications does it hold?

Yes, MLX90366LVS-AEX-253-RE is AEC-Q100 qualified (Grade 0, −40 °C to +150 °C), RoHS-compliant (DMP-4 package), and designed for automotive powertrain and chassis applications. It meets stringent EMC requirements and includes built-in diagnostics such as broken-track detection, overvoltage protection, and supply monitoring - fulfilling functional safety prerequisites for ASIL-A systems.
