Product details
Overview
MLX90372GVS-ACC-308-SP from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute rotary and linear position sensing. It delivers SENT or PWM output, operates from -40°C to +160°C, features ISO26262 ASIL-C safety compliance, and supports programmable 16- or 32-point piecewise linear transfer characteristics. It is used in automotive throttle and steering wheel position sensing with stray-field immunity.
For engineers reviewing the MLX90372GVS-ACC-308-SP datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DMP-4 Pinout-B), confirmed SENT/PWM dual-output capability, functional safety architecture per ISO26262 ASIL-C, AEC-Q100 qualification, and real-world angular/linear position decoding performance.
Technical Context
The MLX90372GVS-ACC-308-SP implements Triaxis® Hall sensing to resolve Bx, By, and Bz magnetic field components simultaneously, enabling robust absolute angle measurement without mechanical contact. Its on-chip DSP performs real-time signal conditioning, filtering, and piecewise linear interpolation using up to 32 user-defined points.
It supports SENT SAE J2716 APR2016 (3µs tick mode) and configurable PWM output, with built-in diagnostics including intelligent watchdog (20 ms timeout), analog/digital diagnostic cycle times (17–34 ms), and fail-safe state activation within 11.9 ms after digital fault detection.
