Product details
Overview
MLX90367LDC-ACX-000-RE from Melexis is a Triaxis® Hall-effect position sensor IC delivering absolute rotary or linear position sensing via 3-axis magnetic field (BX, BY, BZ) decoding. It features SENT output per SAE J2716-2010, 12-bit resolution with 10-bit thermal accuracy, programmable 17-point linear transfer characteristic, and on-chip thermal output offset correction. It operates from −40 °C to +150 °C in SOIC-8 package and is used in automotive throttle, steering, and pedal position sensing.
For engineers reviewing the MLX90367LDC-ACX-000-RE datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, real-world design meaning of key specs, validated SOIC-8 pin functions, application-specific implementation value, and two confirmed alternative parts for position-sensing systems requiring SENT interface and thermal drift compensation.
Technical Context
The MLX90367LDC-ACX-000-RE integrates a Triaxis® Hall sensor front-end with integrated magneto-concentrator (IMC), a 16-bit RISC DSP performing CoRDiC-based rectangular-to-polar conversion, and SENT protocol encoder supporting both Throttle and Secure Sensor frame formats. Its dual-die redundancy is excluded - this variant uses single-die SOIC-8 construction.
It implements configurable FIR filtering (FILTER = 0/1/2), supports user-programmable 17-point LNR transfer curves, and includes active diagnostics (broken VDD/VSS detection), EEPROM-traceable 48-bit ID, and thermal offset correction calibrated at factory and enabled in ACX option code.
