Product details
Overview
MLX90366LVS-ADS-251-SP 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 output via SENT protocol (SAE J2716-2010), with 17-point programmable transfer characteristic, on-board diagnostics, and automotive-grade thermal stability (−40°C to +150°C). It enables non-contacting rotary and linear position sensing in throttle, pedal, and steering applications without a PCB.
For engineers reviewing the MLX90366LVS-ADS-251-SP 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 alternatives for automotive position-sensing designs.
Technical Context
The MLX90366LVS-ADS-251-SP integrates a 16-bit RISC DSP core running at 10 MHz (2.5 MIPS), co-located with analog front-end circuitry that digitizes orthogonal and parallel magnetic flux components. Its CoRDiC-based coordinate rotation engine computes absolute angle from raw sine/cosine signals with 15-bit ADC resolution.
It implements SENT output per SAE J2716-2010 Throttle Sensor format, delivering fast-channel position data (12-bit) plus slow-channel enhanced serial messages containing diagnostics, user-defined IDs, and error codes. The ADS-251 variant supports 17-point piecewise-linear (LNR) transfer function programming but excludes thermal output offset correction (a feature reserved for AxX-xxx variants).

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-253-SP | Same DMP-4 package and SENT interface; supports 17-point LNR calibration but lacks EEPROM lock (unlike ADS-251) | Preferred where field reprogramming of transfer curve is required post-assembly | Select AEV-253 when end-user calibration updates must be supported during service or production test |
| MLX90366LVS-AEX-250-SP | Includes thermal output offset correction (not present in ADS-251); uses STD1 1.27 mm pitch instead of 2.54 mm | Better suited for high-precision applications requiring <±0.15° angular error over full temperature range | Choose AEX-250 when thermal drift compensation is mandatory and board layout accommodates finer pitch |
Compared with MLX90366LVS-ADS-251-SP, AEV-253 offers greater field-programmability at the cost of reduced security locking, while AEX-250 adds thermal offset correction but requires different PCB land pattern-neither is pin-compatible due to differing package pitch and internal configuration defaults.

FAQ
What is the SENT frame structure used by MLX90366LVS-ADS-251-SP?
The MLX90366LVS-ADS-251-SP implements the SAE J2716-2010 Throttle Sensor format: each 882 μs SENT frame contains a 4-nibble fast channel (12-bit position + status bits) followed by optional slow-channel enhanced serial messages. Frame synchronization uses pause pulses, and diagnostic codes are embedded within the fast channel per specification section 13.2.2.
Does MLX90366LVS-ADS-251-SP support thermal output offset correction?
No, MLX90366LVS-ADS-251-SP does not include thermal output offset correction. That feature is exclusive to AxX-xxx option codes (e.g., AEX-250). The ADS-251 variant supports 17-point LNR calibration and diagnostics but relies on factory-trimmed thermal performance, with typical angular error of ±0.3° over −40°C to +125°C per datasheet section 8.
What package variant does MLX90366LVS-ADS-251-SP use, and what are its mounting requirements?
MLX90366LVS-ADS-251-SP uses the DMP-4 package in STD1 2.54 mm pitch configuration (datasheet section 19.2). It requires no PCB for module integration-direct die attachment to housing with magnet alignment is supported. Mounting must respect sensitive spot positioning per section 19.6 and avoid mechanical stress on leads during reflow or assembly.
How is the 17-point transfer function programmed in MLX90366LVS-ADS-251-SP?
The 17-point piecewise-linear (LNR) transfer function in MLX90366LVS-ADS-251-SP is programmed via Melexis' PTM (Programmable Transfer Matrix) tool using I²C or SENT-based bootloader mode. Parameters include LNRAX–LNRCS coordinates stored in EEPROM; programming occurs during final test or calibration, and the ADS-251 variant permits full user access without lock restrictions.
What diagnostic capabilities does MLX90366LVS-ADS-251-SP provide?
MLX90366LVS-ADS-251-SP provides on-chip diagnostics including broken-track detection (VSS/VDD open), supply fault reporting (MT4V/MT7V thresholds), SENT error code transmission, and internal signal path validation. Diagnostic status is delivered via dedicated bits in the fast channel and enhanced serial messages in the slow channel, per sections 14.6 and 15 of the datasheet.
