Product details
Overview
MLX90366LVS-AEU-468-SP from Melexis is a Triaxis® monolithic Hall-effect position sensor IC that measures absolute rotary or linear position via orthogonal and parallel magnetic flux components (Bx, By, Bz). It delivers 12-bit resolution with 10-bit thermal accuracy, SENT output compliant with SAE J2716-2010, and operates across −40 °C to +150 °C. Used in automotive pedal and steering wheel position sensing.
For engineers reviewing the MLX90366LVS-AEU-468-SP datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SENT timing parameters, thermal offset correction capability, AEC-Q100 qualification status, and DMP-4 package integration details for robust non-contacting position sensing design.
Technical Context
The MLX90366LVS-AEU-468-SP implements a 16-bit RISC DSP core running at 10 MHz (2.5 MIPS) to compute angular or linear position from raw sine/cosine ADC outputs. Its Triaxis® architecture uses integrated magneto-concentrators (IMC®) to sense all three magnetic field components simultaneously.
It supports SENT output in Throttle Sensor or Secure Sensor format with fast-channel diagnostics, slow-channel enhanced serial messages, and programmable 17-point piecewise-linear transfer characteristics. The AEU-468 variant includes thermal output offset correction and STD4 2.54 trim-and-form configuration per DMP-4 package outline.

IC Role / Device Role / Timing Role: Non-contacting linear position sensor operating in harsh chemical and vibration environments without sealing compromises. Use Value: DMP-4 package enables direct encapsulation; no PCB required reduces moisture ingress risk and improves long-term stability vs. traditional potentiometers. |
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-258-RE | Lacks thermal output offset correction; uses STD2 2.54 trim-and-form; 17-pt LNR only (no thermal compensation) | Suitable for less demanding thermal environments where <±0.3° drift is acceptable | Select when cost sensitivity outweighs need for full temperature compensation in pedal or throttle modules |
| MLX90366LVS-AEX-250-RE | Includes thermal offset correction but uses STD1 1.27 trim-and-form; different EEPROM lock and diagnostic defaults | Better suited for compact space-constrained designs requiring same thermal performance in smaller footprint | Choose for new designs needing thermal correction where board layout favors 1.27 mm pitch over 2.54 mm |
Compared with MLX90366LVS-AEU-468-SP, the AEV-258 offers identical core sensing and SENT functionality but omits thermal offset correction-reducing calibration complexity at the expense of high-temperature accuracy. The AEX-250 retains thermal correction but shifts to a finer-pitch STD1 package, trading mechanical robustness for miniaturization.

FAQ
What is the SENT protocol compliance level of the MLX90366LVS-AEU-468-SP?
The MLX90366LVS-AEU-468-SP implements SENT output fully compliant with SAE J2716-2010, supporting both Throttle Sensor and Secure Sensor frame formats. It delivers fast-channel diagnostics, slow-channel enhanced serial messages, and configurable pause pulses. Each SENT frame has a fixed 882 μs period, and the IC includes built-in CRC checking per the 2010 standard. This ensures interoperability with standard automotive ECUs and diagnostic tools without external protocol translation.
Does the MLX90366LVS-AEU-468-SP require an external microcontroller to configure its transfer function?
No, the MLX90366LVS-AEU-468-SP contains an embedded 16-bit RISC DSP and 128 B EEPROM, enabling full end-user programming of its 17-point piecewise-linear transfer characteristic, thermal offset correction, diagnostics, and SENT message content without external MCU involvement. Configuration is performed via Melexis' PTM software using a standard SENT-compatible programmer, and settings persist through power cycles. The MLX90366LVS-AEU-468-SP executes all signal processing-including CoRDiC-based angle computation and FIR filtering-on-chip.
How does the thermal output offset correction in the MLX90366LVS-AEU-468-SP improve system-level accuracy?
The thermal output offset correction feature in the MLX90366LVS-AEU-468-SP actively compensates for temperature-induced zero-point drift in the magnetic front-end, reducing angular error to ±0.3° over −40 °C to +150 °C. This is achieved by applying calibrated correction coefficients stored in EEPROM during DSP processing. For example, in a throttle position sensor, this eliminates the need for ECU-side temperature lookup tables or dual-sensor redundancy, directly improving air-fuel ratio stability and emissions compliance without increasing software overhead or BOM cost.
What package dimensions and mounting requirements apply to the MLX90366LVS-AEU-468-SP?
The MLX90366LVS-AEU-468-SP uses the DMP-4 package with STD4 2.54 trim-and-form lead configuration-meaning 2.54 mm pitch, 4-pin gull-wing leads, and standardized outline per Melexis POD document STD4 2.54. It requires reflow soldering per JEDEC J-STD-020, with peak temperature ≤260 °C. The sensitive spot is centered on the die surface; mechanical alignment must respect ±0.3 mm tolerance relative to magnet center. No PCB is needed-the device is designed for direct integration into molded sensor housings using wire bonding.
Is the MLX90366LVS-AEU-468-SP pin-compatible with other MLX90366 variants such as AEU-250 or AEV-258?
Yes, all MLX90366 variants-including MLX90366LVS-AEU-468-SP, MLX90366LVS-AEU-250-RE, and MLX90366LVS-AEV-258-RE-share identical DMP-4 4-pin pinout (VSS, VDD, OUT, VSS) and mechanical footprint. However, functional differences exist: AEU-468 includes thermal offset correction and uses STD4 2.54 leads, while AEU-250 uses STD1 1.27 and AEV-258 omits thermal correction. Electrical compatibility is maintained, but firmware and calibration must match the specific option code's EEPROM structure and feature set.
