Product details
Overview
MLX90366LVS-AEU-460-RE from Melexis is a Triaxis® monolithic absolute position sensor IC using Hall-effect and integrated magneto-concentrator (IMC) technology to measure Bx, By, and Bz field components. It delivers 12-bit resolution with 10-bit thermal accuracy, SENT output per SAE J2716-2010, on-board diagnostics, and operates across −40 °C to +150 °C. It enables non-contact rotary/linear sensing in automotive throttle and steering wheel position systems.
For engineers reviewing the MLX90366LVS-AEU-460-RE datasheet, pinout, applications, or equivalent options, this page provides verified functional context, SENT timing compliance, thermal offset correction capability, DMP-4 package mapping, and AEC-Q100 qualification details essential for automotive-grade position-sensing design validation.
Technical Context
The MLX90366LVS-AEU-460-RE implements a 16-bit RISC DSP core running at 10 MHz (2.5 MIPS), performing real-time coordinate rotation (CoRDiC) to compute absolute angle from orthogonal magnetic field components. Its IMC-enhanced front-end supports ±1 T magnetic flux density with programmable gain (k = 1–1.5) and factory-trimmed orthogonality compensation.
This variant (AEU-460) features 17-point piecewise-linear transfer characteristic programming, SENT Throttle Position format output, and thermal output offset correction-enabled via EEPROM-configurable parameters including CLAMPLOW/CLAMPHIGH, DP (discontinuity point), and FILTER settings. All diagnostics-including broken VDD/VSS detection and SENT error code reporting-are implemented in hardware and firmware without external components.

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-AEU-460-RE | Same DMP-4 package and SENT interface, but adds dual-die redundancy and enhanced diagnostics for ASIL-C systems. | Required where fault-tolerant dual-channel operation is mandated (e.g., steer-by-wire primary sensing). | Select MLX90367 when functional safety integrity exceeds ASIL-B; otherwise MLX90366LVS-AEU-460-RE suffices for standard throttle/pedal use. |
| TLV493DW2B6HTSA1 | Infineon 3D Hall sensor with I²C output; 12-bit resolution but no SENT, no thermal offset correction, and narrower temp range (−40 °C to +125 °C). | Suitable for industrial linear encoders or non-automotive rotary feedback where SENT is not required. | Choose TLV493DW2B6HTSA1 only for cost-sensitive, non-automotive designs lacking SENT infrastructure or extended temperature needs. |
Compared with MLX90367LVS-AEU-460-RE, the MLX90366LVS-AEU-460-RE reduces system cost and complexity by omitting redundant die while retaining full SENT compliance and thermal correction-making it optimal for single-channel automotive position sensing. Versus TLV493DW2B6HTSA1, it delivers automotive-grade robustness, SENT-native ECU compatibility, and guaranteed performance up to +150 °C.

FAQ
What is the SENT frame period and latency behavior of the MLX90366LVS-AEU-460-RE?
The MLX90366LVS-AEU-460-RE outputs SENT frames every 882 µs. Total latency from magnetic field change to valid SENT data is 1745 µs when FILTER = 1 (recommended setting). First sync pulse appears within 1.8 ms of power-up, and first data is delivered within 6.3 ms. These timing values are fixed per datasheet Section 7 and confirmed for the AEU-460 option code.
Does the MLX90366LVS-AEU-460-RE support thermal output offset correction, and how is it enabled?
Yes, the MLX90366LVS-AEU-460-RE includes thermal output offset correction, a feature specific to the AxX-xxx and AEU-xxx option codes. It is enabled via EEPROM configuration of the THERMAL_OFFSET_CORR parameter during end-user programming. This correction reduces angular error to <±0.3° over −40 °C to +150 °C, as validated in Accuracy Specification Table 8.
What magnetic field strengths are required for reliable operation of the MLX90366LVS-AEU-460-RE?
The MLX90366LVS-AEU-460-RE requires √(Bx² + By²) ≥ 70 mT for XY-axis operation and Bz ≥ 126 mT for Z-axis sensing. The magnetic flux norm √(Bx² + By² + (Bz/1.2)²) must exceed 20 mT for optimal SNR. Operation below 20 mT degrades noise performance; above 70 mT, IMC saturation increases linearity error-both thresholds are specified in Magnetic Specification Table 9.
How is the 17-point transfer characteristic programmed in the MLX90366LVS-AEU-460-RE?
The 17-point piecewise-linear (LNR) transfer characteristic is programmed into the MLX90366LVS-AEU-460-RE's 128 B EEPROM using Melexis' PTM (Programmable Transfer Matrix) tool. Parameters include LNRAX–LNRCS coordinates, DP (discontinuity point), and CW (clockwise direction flag). Programming occurs post-manufacture and is retained across power cycles per Section 14.1.4 of the datasheet.
Is the MLX90366LVS-AEU-460-RE pin-compatible with other MLX90366 variants in the DMP-4 package?
Yes, all MLX90366 variants in the DMP-4 package-including MLX90366LVS-AEU-460-RE-share identical 4-pin pinout (VSS, VDD, OUT, VSS), mechanical footprint, and soldering profile. Differences are limited to EEPROM content, factory trim, and option-code-specific features (e.g., thermal correction), not electrical or physical interface.
