Product details

Overview

MLX90366LVS-AEU-250-RX 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 resolution with 10-bit thermal accuracy, SENT output compliant with SAE J2716-2010 (Throttle Sensor format), and operates across −40 °C to +150 °C for automotive pedal and steering wheel position sensing.

For engineers reviewing the MLX90366LVS-AEU-250-RX datasheet, pinout, applications, or equivalent options, this page provides verified functional context, SENT timing compliance, thermal offset correction capability, AEC-Q100 qualification, and DMP-4 package integration details required for robust non-contacting position sensor design.

Technical Context

The MLX90366LVS-AEU-250-RX implements a 16-bit RISC DSP core running at 10 MHz (2.5 MIPS) to compute angular or linear position from raw Bx/By/Bz ADC samples. Its architecture includes on-chip IMC® magneto-concentrator, programmable piecewise-linear transfer characteristic (17-point LNR), and dual-stage diagnostics covering broken track, overvoltage, and thermal faults.

It supports SENT frame transmission with configurable fast channel (throttle position or secure sensor format), slow channel enhanced serial messages, and field-sensing synchronization pulses. The AEU-250 variant enables 17-point linearization and thermal output offset correction-confirmed in Section 14.1.6 of the datasheet for AxX-xxx and AEU-xxx option codes.
