Product details
Overview
MLX90366LVS-ADS-250-TU from Melexis is a Triaxis® monolithic absolute position sensor IC using Hall-effect technology to measure orthogonal (Bx, By) and parallel (Bz) magnetic flux components. It delivers 12-bit angular/linear position data via SENT output (SAE J2716-2010), features 17-point programmable piecewise-linear transfer characteristic, on-board diagnostics, and operates across −40 °C to +150 °C for automotive pedal and steering position sensing.
For engineers reviewing the MLX90366LVS-ADS-250-TU datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SENT timing compliance, thermal offset correction capability, DMP-4 package mapping, and validated automotive-grade alternatives for throttle, ride height, and non-contacting potentiometer designs.
Technical Context
The MLX90366LVS-ADS-250-TU integrates a 16-bit RISC DSP core running at 10 MHz (2.5 MIPS) with dedicated analog front-end for simultaneous Bx, By, Bz field acquisition. Its CoRDiC-based angle computation supports rotary (0–360°) and linear displacement decoding using IMC-enhanced magnetic sensitivity (GainIMCXY = 1.2–1.8×).
This variant implements the ADS-xxx option code, enabling full 17-point LNR parameter programming for high-fidelity transfer curve shaping, SENT frame transmission at 882 μs period, and internal diagnostics including broken-track detection, over-voltage protection, and thermal offset monitoring - all without external PCB routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Interface | SENT (SAE J2716-2010 Throttle Sensor format), 882 μs frame period - enables direct connection to automotive ECUs without protocol translation. |
| Position Resolution | 12-bit digital output with 10-bit thermal accuracy - ensures stable angular reporting under temperature cycling in engine bay environments. |
| Magnetic Sensing | Triaxis® (Bx, By, Bz) with integrated magneto-concentrator - allows single-chip absolute position measurement using off-axis or axial magnets. |
| Accuracy | ±0.3° XY intrinsic linearity error at 25 °C - supports high-precision pedal and steering wheel position feedback. |
| Operating Range | −40 °C to +150 °C ambient - qualified per AEC-Q100 Grade 0, suitable for under-hood and transmission-mounted applications. |
| Supply Voltage | 4.5–5.5 V nominal, 24 V absolute max - withstands load-dump transients common in 12 V automotive systems. |
| Programmability | 17-point piecewise-linear transfer function (ADS-xxx) - enables end-user calibration for custom mechanical stroke profiles. |

FAQ
What is the SENT frame structure used by MLX90366LVS-ADS-250-TU?
The MLX90366LVS-ADS-250-TU implements the SAE J2716-2010 Throttle Sensor format with an 882 μs frame period. Each frame contains 12 nibbles: 4 for position data (12-bit resolution), 2 for status/diagnostic flags, and 6 for OEM-defined serial messages. The fast channel reports real-time errors such as open-load or magnetic saturation, while the slow channel delivers user-programmed identifiers and calibration constants.
Does MLX90366LVS-ADS-250-TU support thermal offset correction?
MLX90366LVS-ADS-250-TU does not include thermal output offset correction - that feature is exclusive to the AxX-xxx option code variants. The ADS-xxx version provides 17-point LNR programmability and standard diagnostics but relies on external calibration or mechanical design to manage thermal drift. For applications requiring active thermal compensation, MLX90366LVS-AEX-250-TU or MLX90366LVS-AEX-253-TU should be selected instead.
What is the maximum magnetic field the MLX90366LVS-ADS-250-TU can measure?
The MLX90366LVS-ADS-250-TU supports magnetic flux densities up to ±1 T (10,000 G) as specified in Absolute Maximum Ratings. However, optimal accuracy is maintained below 70 mT for Bx/By and 126 mT for Bz, as higher fields cause IMC® saturation and increased linearity error. For reliable operation, magnetic circuit design should target 20–50 mT at the die surface under worst-case temperature and air gap conditions.
Can MLX90366LVS-ADS-250-TU operate without an external PCB?
Yes - the MLX90366LVS-ADS-250-TU is packaged in the DMP-4 module, which integrates bond wires, molding compound, and termination pads to enable direct connection to sensor housings or metal substrates. This "no-PCB" architecture eliminates solder joints and vias, increasing mechanical reliability in high-vibration environments like suspension or transmission mounts, and is explicitly supported in Melexis documentation (Section 19.5).
Is MLX90366LVS-ADS-250-TU AEC-Q100 qualified?
Yes, MLX90366LVS-ADS-250-TU is fully qualified to AEC-Q100 Grade 0 (−40 °C to +150 °C), including stress testing for HTSL, TC, UHAST, and ESD per the standard. This qualification is documented in the official Melexis datasheet (Revision 002, Page 1) and applies specifically to the L-temperature code and VS-package variants, confirming suitability for safety-critical automotive subsystems.
