Product details
Overview
MLX90366LVS-ADS-250-RX from Melexis is an AEC-Q100 qualified Triaxis® absolute position sensor IC using Hall-effect 3D magnetic field sensing (Bx, By, Bz) to deliver 12-bit angular/linear position data via SENT output (SAE J2716-2010). It operates from −40 °C to +150 °C, features 17-point programmable transfer characteristic, on-board diagnostics, and thermal offset correction - enabling high-accuracy non-contact sensing in automotive throttle and steering wheel position systems.
For engineers reviewing the MLX90366LVS-ADS-250-RX datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, SENT timing compliance, DMP-4 package integration details, and validated alternative options for automotive-grade position sensing designs.
Technical Context
The MLX90366LVS-ADS-250-RX implements a CoRDiC-based DSP architecture to compute absolute angle or linear displacement from orthogonal (Bx, By) and parallel (Bz) magnetic flux components. Its 17-point piecewise-linear (PWL) transfer function is user-programmable via EEPROM, supporting precise calibration across mechanical tolerances and temperature drift.
It outputs SENT frames in Throttle Sensor format with dual-channel capability: fast channel delivers primary position data (12-bit resolution), while slow channel transmits enhanced serial messages including diagnostics, 48-bit ID, and OEM-defined values - all synchronized to internal 13.3 MHz clock with ±3% thermal drift.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Interface | SENT compliant with SAE J2716-2010, Throttle Sensor format - enables direct connection to automotive ECUs without protocol translation. |
| Position Resolution | 12-bit digital output (4096 steps) with 10-bit thermal accuracy - ensures stable angular reporting over full −40 °C to +150 °C range. |
| Magnetic Sensing | Triaxis® 3D Hall sensing (Bx, By, Bz) - supports both rotary (0–360°) and linear stroke measurement with single IC. |
| Transfer Function | 17-point piecewise-linear (PWL) programmability - allows end-user calibration to compensate for magnet/mounting non-idealities. |
| Diagnostic Coverage | On-chip diagnostics including broken VDD/VSS detection, output short-circuit monitoring, and SENT error code reporting - meets ASIL-B functional safety requirements. |
| Supply Range | 4.5 V to 5.5 V nominal; survives up to +24 V overvoltage - suitable for 12 V automotive battery environments with load-dump transients. |
| Package | DMP-4 (Dual Mold Package), STD1 2.54 mm pitch - surface-mount, RoHS-compliant, no-PCB module integration enabled. |
Pinout & Package
DMP-4 is a 4-pin dual-mold surface-mount package with integrated leadframe, optimized for robust automotive mounting and direct magnet coupling. Pin 1 and Pin 4 are both VSS (ground); either may be used, but Pin 1 must remain floating when Pin 4 is connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS (Ground) | Ground reference terminal - must be left floating if Pin 4 is used for grounding; ensures proper IMC® magnetic field coupling. |
| 2 | VDD | Power supply input (4.5–5.5 V) - includes overvoltage protection up to +24 V and under-voltage detection at 3.8–4.2 V. |
| 3 | OUT | SENT serial output (open-drain) - delivers calibrated position data and diagnostics in SAE J2716-compliant nibble frames. |
| 4 | VSS (Ground) | Primary ground connection - low-inductance path for noise immunity; required for thermal offset correction stability. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Magnetic Sensing | Simultaneous Bx, By, Bz measurement enables single-IC solutions for rotary, linear, and tilt position - eliminating multi-sensor assemblies. |
| 17-Point PWL Programmability | End-user configurable transfer curve compensates for mechanical hysteresis, magnet tolerance, and air-gap variation - reduces system-level calibration effort. |
| SENT Fast + Slow Channel | Fast channel delivers primary position data every 882 μs; slow channel adds diagnostics, ID, and OEM fields - supports ASIL-B diagnostic coverage without external microcontroller. |
| Thermal Offset Correction | Compensates for temperature-induced zero-point drift in XY plane - maintains ≤ ±0.3° angular error from −40 °C to +125 °C (per datasheet Section 8). |
| AEC-Q100 Grade 0 | Qualified for automotive applications up to +150 °C ambient - validated for engine bay, transmission, and chassis-mounted position sensing. |
Applications
| Throttle Position Sensing | Steering Wheel Angle Sensing |
|---|---|
Use Scenario: Real-time detection of accelerator pedal rotation in gasoline/diesel powertrains with fail-safe redundancy. IC Role / Device Role / Timing Role: Primary absolute angle sensor delivering SENT-encoded position at 1.13 kHz frame rate with <1.75 ms total latency.

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-250-RX | Includes thermal output offset correction (AxX-xxx option), higher EEPROM endurance (100k cycles vs. 10k), and enhanced SENT slow-channel payload. | Required where >125 °C operation or long-term thermal drift compensation beyond ±0.3° is mandated. | Select when thermal offset correction across full −40 °C to +150 °C is critical; not drop-in due to different EEPROM programming flow. |
| TLE5012BE1500XUMA1 | Uses Biss-C interface instead of SENT; 14-bit resolution; integrated SPI diagnostics; no 17-point PWL - only 3-point calibration. | Suitable for systems with existing Biss-C infrastructure or requiring SPI-configurable diagnostics, but lacks SENT-native ECU compatibility. | Choose for industrial servo drives or non-automotive platforms; requires protocol translation layer for legacy SENT ECUs. |
Compared with MLX90366LVS-ADS-250-RX, the MLX90367 variant adds full-range thermal offset correction and higher EEPROM reliability for mission-critical automotive modules, while the TLE5012B offers SPI flexibility at the cost of SENT interoperability and reduced calibration granularity.

FAQ
What is the SENT frame period and latency behavior of the MLX90366LVS-ADS-250-RX?
The MLX90366LVS-ADS-250-RX outputs SENT frames every 882 μs (tframe). Total field-to-data latency is 1745 μs when FILTER = 1 (recommended setting), comprising internal angle measurement (441 μs), processing, and SENT transmission. First sync pulse appears within 1.8 ms of power-up, and first valid data within 6.3 ms. These values are confirmed in Section 7 of the official datasheet revision 002.
Does the MLX90366LVS-ADS-250-RX support programmable transfer characteristics, and how many points are available?
Yes, the MLX90366LVS-ADS-250-RX supports end-user programmable transfer characteristics via EEPROM. The ADS-xxx option code specifies 17-point piecewise-linear (PWL) configuration - allowing precise calibration of position output across full mechanical range to compensate for magnet placement, air gap, and mechanical hysteresis.
Is the MLX90366LVS-ADS-250-RX qualified for automotive use, and what is its temperature rating?
Yes, the MLX90366LVS-ADS-250-RX is AEC-Q100 qualified (Grade 0) and rated for operation from −40 °C to +150 °C ambient temperature. This qualification covers thermal cycling, humidity, mechanical shock, and ESD robustness - making it suitable for under-hood and transmission-mounted position sensing applications.
What package type does the MLX90366LVS-ADS-250-RX use, and are both ground pins mandatory?
The MLX90366LVS-ADS-250-RX uses the DMP-4 package (Dual Mold Package) with 2.54 mm pitch. Pin 1 and Pin 4 are both labeled VSS, but only one ground connection is required: Pin 4 must be used as the primary ground, while Pin 1 must remain floating to ensure correct magnetic field coupling to the IMC® structure.
How does the MLX90366LVS-ADS-250-RX handle diagnostics, and what fault conditions does it report?
The MLX90366LVS-ADS-250-RX provides on-board diagnostics including broken VDD/VSS detection, output short-circuit monitoring, and SENT error codes (e.g., CRC failure, invalid frame). Diagnostic status is reported via dedicated bits in the SENT slow channel, and analog saturation levels (Dsat_lo/Dsat_hi) indicate active faults - all detailed in Sections 14.6 and 15 of the datasheet.
