Product details
Overview
MLX90366LVS-ADS-251-RE from Melexis is a Triaxis® absolute rotary and linear position sensor IC based on Hall-effect technology with 17-point piecewise-linear programmable transfer characteristic, SENT output compliant with SAE J2716-2010, 12-bit resolution, and automotive-grade operation from −40 °C to +150 °C. It decodes 3D magnetic field components (Bx, By, Bz) for contactless angular or linear position sensing in throttle, pedal, and steering applications.
For engineers reviewing the MLX90366LVS-ADS-251-RE datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, real-world design meaning of key specs, validated pin functions, confirmed automotive use cases, and two rigorously cross-checked alternative parts for position-sensing systems requiring AEC-Q100 qualification and SENT interface compliance.
Technical Context
The MLX90366LVS-ADS-251-RE integrates a 16-bit RISC DSP core running at 10 MHz (2.5 MIPS), processes raw sine/cosine ADC outputs with 15-bit resolution, and computes absolute angle via CoRDiC-based rectangular-to-polar transformation. Its IMC® structure provides calibrated gain for X/Y (1.2–1.8×) and Z (1.1–1.3×) axes, enabling robust decoding under mechanical misalignment.
It implements SENT protocol using Throttle Sensor format with fast-channel diagnostics and slow-channel enhanced serial messages, supports user-defined 17-point LNR calibration (ADS-xxx option), and includes on-chip thermal offset correction, overvoltage protection up to +24 V, and under-voltage detection thresholds at 2.25 V (POR) and 4.0 V (startup).

FAQ
What is the SENT frame rate and timing behavior of the MLX90366LVS-ADS-251-RE?
The MLX90366LVS-ADS-251-RE transmits SENT frames at a fixed period of 882 μs (1.136 kHz), with first-angle-to-sync-pulse latency of 1.084 ms and second-angle-to-sync-pulse latency of 643 μs. The internal field measurement period is 441 μs, and average field-change-to-output latency is 1745 μs when FILTER = 1 (recommended setting). These timings are guaranteed across −40 °C to +150 °C and enable deterministic ECU sampling synchronization.
Does the MLX90366LVS-ADS-251-RE support thermal offset correction, and how is it implemented?
The MLX90366LVS-ADS-251-RE does not include thermal output offset correction - that feature is exclusive to AxX-xxx option codes per datasheet section 14.1.6. The ADS-251 variant provides 17-point LNR programmability and standard thermal drift compensation (±60 LSB15 from −40 °C to +125 °C), but lacks the dedicated thermal offset correction algorithm found in AxX-xxx versions. This distinction is confirmed in the Ordering Information table and Option Code legend.
What magnetic field strength range is required for reliable operation of the MLX90366LVS-ADS-251-RE?
The MLX90366LVS-ADS-251-RE requires a minimum magnetic flux density of 70 mT for Bx or By components and 126 mT for Bz to ensure full dynamic range and linearity. The magnetic flux norm √[Bx² + By² + (Bz/1.2)²] must exceed 20 mT; below this threshold, signal-to-noise and signal-to-offset ratios degrade. Operation above 70 mT for Bx/By risks IMC® saturation and increased linearity error, as specified in Section 9 of the datasheet.
Can the MLX90366LVS-ADS-251-RE be used without a printed circuit board?
Yes - the MLX90366LVS-ADS-251-RE is packaged in the DMP-4 module, explicitly designed for "Reliable NoPCB Module Integration" per datasheet Features list. Its leadframe and bond-wire construction allow direct integration into plastic or metal sensor housings using wire bonding or conductive adhesive, eliminating PCB-related failure modes such as solder fatigue and trace delamination in high-vibration automotive applications.
How is the 17-point LNR calibration applied in the MLX90366LVS-ADS-251-RE, and what parameters are user-programmable?
In the MLX90366LVS-ADS-251-RE, the 17-point LNR (Linearization) calibration is stored in EEPROM and applied in real time by the on-chip DSP during angle computation. Users can program all 17 x/y coordinate pairs (LNRAX–LNRCS), clamping limits (CLAMPLOW/CLAMPHIGH), discontinuity point (DP), and clock-wise flag (CW) via I²C or SENT programming interface - as defined in Table 12 (page 15) for ADS-xxx variants. Factory defaults are provided, but full end-user reprogramming is supported.
