Product details

Overview

MLX90366LVS-AEX-258-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 and is AEC-Q100 qualified for automotive pedal, throttle, and steering wheel position sensing.

For engineers reviewing the MLX90366LVS-AEX-258-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 alternatives for non-contacting position sensing in harsh environments.

Technical Context

The MLX90366LVS-AEX-258-RE measures all three orthogonal magnetic field components (B_x, B_y, B_z) using integrated magneto-concentrators (IMC®) and computes absolute angular or linear position via CoRDiC-based DSP. Its 17-point piecewise-linear transfer characteristic is user-programmable and includes thermal output offset correction - a feature exclusive to the AEX option code.

It outputs SENT frames in Throttle Sensor or Secure Sensor format with diagnostic reporting on fast and slow channels, supports configurable FIR filtering (FILTER = 0/1/2), and delivers synchronized angle measurements every 441 μs with 1745 μs total latency (FILTER = 1). The device integrates 10 KB ROM, 384 B RAM, and 128 B EEPROM for calibration and ID storage.

Equivalent & Alternatives

The following parts are listed as comparable options for similar absolute position sensing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MLX90367LVS-AEX-258-RE	Same DMP-4 package and AEX option; adds dual-die redundancy and enhanced diagnostic coverage per ISO 26262 ASIL-B requirements	Required for safety-critical steering angle or brake pedal applications where fault tolerance is mandated	Select MLX90367 when dual-die redundancy and ASIL-B certification are required; otherwise MLX90366LVS-AEX-258-RE suffices for ASIL-A or non-safety systems
AMS AS5055A-BQFT	14-bit SPI/I²C output; no SENT interface; lacks thermal offset correction and IMC-enhanced Z-axis sensitivity	Suitable for industrial encoders or consumer devices where SENT is not mandated and ambient temperature stays below 105 °C	Choose AS5055A-BQFT for cost-sensitive, non-automotive designs needing higher resolution but no automotive diagnostics or extreme temp operation

Compared with MLX90367LVS-AEX-258-RE, the MLX90366LVS-AEX-258-RE provides identical core sensing and SENT functionality at lower cost and complexity, while AMS AS5055A-BQFT offers higher resolution but omits automotive-grade diagnostics, thermal compensation, and SENT compliance - limiting its suitability for under-hood deployment.

FAQ

What is the SENT protocol compliance level of the MLX90366LVS-AEX-258-RE?

The MLX90366LVS-AEX-258-RE fully complies with SAE J2716-2010 for SENT output, supporting both Throttle Sensor and Secure Sensor frame formats. It delivers 12-bit position data with embedded diagnostics, error codes, and OEM-defined serial messages on fast and slow channels - all verified per Section 13 of the official datasheet Rev 002.

Does the MLX90366LVS-AEX-258-RE support thermal output offset correction?

Yes, thermal output offset correction is explicitly enabled in the AEX option code, as confirmed in Section 14.1.6 of the datasheet. This feature corrects zero-point drift over temperature and is active across the full −40 °C to +150 °C range, distinguishing MLX90366LVS-AEX-258-RE from ADU/AEV variants.

What package type and pin configuration does the MLX90366LVS-AEX-258-RE use?

The MLX90366LVS-AEX-258-RE uses the DMP-4 package with STD4 2.54 mm trim-and-form configuration (Section 19.4), featuring four terminals: VSS (Pin 1, floating), VDD (Pin 2), OUT (Pin 3), and VSS (Pin 4, primary ground). Pin 1 must remain unconnected when Pin 4 is used for grounding.

How does the MLX90366LVS-AEX-258-RE achieve absolute position sensing without a multi-turn mechanism?

The MLX90366LVS-AEX-258-RE achieves absolute position by measuring all three orthogonal magnetic field components (B_x, B_y, B_z) simultaneously using integrated magneto-concentrators (IMC®) and computing angle via CoRDiC-based DSP. This eliminates need for gears, cams, or multi-turn encoding - enabling true 0–360° rotary or full-stroke linear measurement from a single magnet motion.

Is the MLX90366LVS-AEX-258-RE qualified for automotive applications?

Yes, the MLX90366LVS-AEX-258-RE is AEC-Q100 qualified (Grade 0) for operation from −40 °C to +150 °C ambient, includes built-in diagnostics (broken VDD/VSS, short-circuit, EEPROM CRC), and meets automotive EMC and reliability standards - making it suitable for throttle, pedal, and steering position sensing in production vehicles.
