Product details

Overview

MLX90366LVS-ADU-251-SP from Melexis is an AEC-Q100 qualified Triaxis® absolute position sensor IC using Hall-effect technology to measure Bx, By, and Bz magnetic field components. It delivers 12-bit resolution with 10-bit thermal accuracy, SENT output per SAE J2716-2010 (Throttle format), and operates across −40 °C to +150 °C for automotive pedal and steering wheel position sensing.

For engineers reviewing the MLX90366LVS-ADU-251-SP datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SENT timing compliance, thermal offset correction capability, programmable multi-point transfer characteristic, and DMP-4 package integration details essential for non-contacting rotary/linear sensor design.

Technical Context

The MLX90366LVS-ADU-251-SP implements a 16-bit RISC DSP core running at 10 MHz (2.5 MIPS) to compute absolute angular or linear position from raw sine/cosine ADC outputs (15-bit resolution). Its Triaxis® architecture enables orthogonal and parallel flux density sensing via integrated magneto-concentrators (IMC), supporting both XY-plane rotation (0–360°) and Z-axis linear displacement.

It uses SENT protocol with configurable fast-channel diagnostics and slow-channel enhanced serial messages, supports on-board EEPROM programming of clamping limits, discontinuity point, clock-wise direction, and 17-point piecewise-linear transfer characteristic (per ADU option code), and includes built-in over-voltage protection, under-voltage detection, and passive/active diagnostic reporting.

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-251-SP	Same DMP-4 package and SENT interface; uses 17-pt PWL but lacks thermal offset correction	Suitable where ambient temperature stability is high and thermal drift compensation is handled externally	Select when lower-cost calibration suffices and thermal offset drift <±0.3° is acceptable
MLX90366LVS-AEU-251-SP	Includes thermal offset correction and 17-pt PWL; differs only in EEPROM lock configuration (lock enabled vs. disabled in ADU)	Preferred for production modules requiring write-protection of calibrated parameters post-configuration	Select when firmware-controlled reprogramming must be prevented after final calibration
