Product details
Overview
MLX90372GDC-ACC-300-SP from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC in SOIC-8 package, delivering absolute rotary or linear position sensing via SENT or PWM output. It operates from -40°C to +160°C, supports programmable 4–32-point piecewise linear transfer characteristics, and meets AEC-Q100 Grade 0 and ISO 26262 ASIL-C safety requirements for automotive pedal and throttle position sensing.
For engineers reviewing the MLX90372GDC-ACC-300-SP datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, SOIC-8 pin mapping, SENT/PWM timing compliance (SAE J2716 APR2016), stray-field robustness data, and real-world automotive use cases with design-meaning specifications.
Technical Context
The MLX90372GDC-ACC-300-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, enabling true 3D field decoding for absolute angular (0–360°) or linear displacement. Its on-chip DSP performs real-time signal conditioning and advanced filtering, supporting both continuous asynchronous acquisition (528–588 µs measurement period) and synchronous SENT frame-aligned modes.
It features dual-domain diagnostics: analog diagnostics cycle time of 34 µs in asynchronous mode and digital diagnostics at 20 ms, plus fail-safe state activation within 9.8–34.6 ms after fault detection. The ACC revision uses push-pull output with Ron ≤ 100 Ω and supports SENT 3 µs tick mode only - no Fast SENT or DMP-4-specific configurations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GDC-ACE-300-RE | ACE revision replaces ACC; adds enhanced diagnostics, improved startup time (11.2 ms), and extended memory lifetime | Same SOIC-8 package and -300 legacy mode; supports identical magnetic configurations and output protocols | Select ACE-300 for new designs requiring longer product lifecycle support and updated safety documentation |
| MLX90371GDC-ACC-300-SP | Single-output SENT-only variant (no PWM); lower current (7.5 mA), same SOIC-8 footprint and pinout | Targeted for cost-sensitive applications where PWM fallback is unnecessary; lacks programmable PWL flexibility | Choose MLX90371 when SENT-only interface suffices and power budget is constrained below 8 mA |
Compared with MLX90372GDC-ACC-300-SP, the ACE-300 offers documented improvements in diagnostic coverage and startup reliability, while the MLX90371 reduces BOM cost and power at the expense of output flexibility and calibration granularity.
