Overview
MLX90376GGO-ABA-630-SP from Melexis is a Triaxis® Hall-based monolithic magnetic position sensor IC for absolute rotary position sensing up to 360°, featuring SENT (SAE J2716 APR2016) output with 3 μs tick time, AEC-Q100 Grade-0 qualification (-40°C to +160°C), and stray-field immunity up to 5 mT per ISO 11452-8. It implements dual-die redundancy in TSSOP-16_EP package and supports ASIL C functional safety for SENT mode.
For engineers reviewing the MLX90376GGO-ABA-630-SP datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, SENT timing compliance, dual-die isolation specs, automotive-grade thermal performance, and real-world use cases in throttle, steering, and ride-height sensing systems.
Technical Context
The MLX90376GGO-ABA-630-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz components, enabling contactless 360° absolute angle measurement without mechanical stops. Its DSP performs on-chip signal conditioning including piecewise-linearization (up to 32 segments) and programmable transfer characteristics.
This variant operates exclusively in Rotary Stray-Field Immune Mode (360°), uses SENT protocol with fixed 3 μs tick time, and resides in TSSOP-16_EP dual-die package with isolated ground/supply domains (Risol ≥ 4 MΩ between dice). It delivers ASIL C compliance via built-in diagnostics including CRC, watchdog timers, and fault-handling time intervals ≤ 10 ms.
Key Specifications
