Product details

Overview

MLX90366LVS-AEV-253-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 rotary or linear position output via SENT protocol (SAE J2716-2010). It provides 12-bit resolution with 10-bit thermal accuracy, on-board diagnostics, and operates across −40 °C to +150 °C for automotive pedal and steering wheel position sensing.

For engineers reviewing the MLX90366LVS-AEV-253-SP datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, SENT timing compliance, thermal offset correction capability, DMP-4 package mapping, and validated alternatives for throttle and ride height sensor designs.

Technical Context

The MLX90366LVS-AEV-253-SP integrates a 16-bit RISC DSP core running at 10 MHz (2.5 MIPS), performing real-time coordinate rotation (CoRDiC) to compute angular position from orthogonal magnetic field components. Its internal IMC structure enables sensitivity gain of 1.2–1.8× in XY and 1.1–1.3× in Z, with programmable k-factor (1.0–1.5) for axis mismatch compensation.

This variant implements 17-point piecewise-linear (PWL) transfer characteristic programming and includes thermal output offset correction - a feature exclusive to AxX-xxx and AEV-xxx option codes per datasheet Section 14.1.6 and Table 1 legend. SENT frame period is fixed at 882 μs with 294-tick encoding, supporting both Throttle Position and Secure Sensor formats with diagnostic error reporting in fast channel.

Equivalent & Alternatives

The following parts are listed as comparable options for similar absolute position sensing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice

The 17-point PWL programming allows custom transfer curves for either mode.

How does thermal output offset correction work in MLX90366LVS-AEV-253-SP?

MLX90366LVS-AEV-253-SP implements active thermal output offset correction by measuring temperature-dependent zero-point drift during operation and applying real-time compensation in the DSP.
