Product details
Overview
MLX90372GVS-ACC-303-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 4–32-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-303-SP datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DMP-4 Pinout-B), confirmed SENT/PWM timing modes, functional safety architecture, and validated alternatives for legacy angular/linear position sensing designs.
Technical Context
The MLX90372GVS-ACC-303-SP implements a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, enabling absolute angle decoding from 0° to 360° or linear displacement without contact. Its on-chip DSP performs real-time signal conditioning, filtering, and piecewise linear interpolation using up to 32 user-defined points.
It supports two timing modes: asynchronous acquisition (528–588 µs measurement period) for SENT without pause and PWM, and synchronous acquisition aligned to SENT frame timing (930–960 µs frame period at 3 µs tick). Output is configurable as SAE J2716 APR2016 SENT (3 µs mode) or PWM with programmable duty cycle.

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GVS-ACE-303-SP | Same DMP-4 Pinout-B package and -303 option code, but ACE chip revision (preferred for new designs) | Identical angular/linear legacy mode functionality; improved startup time (11.2 ms vs 12.4 ms) | Select ACE-303 for new designs requiring full lifecycle support and enhanced diagnostics |
| MLX90371GVS-ACC-303-SP | Single-die predecessor with identical DMP-4 Pinout-B and -303 option, but lacks ASIL-C certification and SENT 3 µs mode | Supports only PWM output and basic diagnostics; not suitable for ASIL-B/C systems | Use only in cost-sensitive legacy upgrades where functional safety is not required |
Compared with MLX90372GVS-ACC-303-SP, the ACE-303 variant offers shorter safe startup time and extended manufacturer support, while the MLX90371GVS-ACC-303-SP lacks SENT capability and safety certification-making it unsuitable for modern automotive safety-critical applications.

Yes, the MLX90372GVS-ACC-303-SP is certified to ISO26262 ASIL-C as a Safety Element out of Context (SEooC) and qualified to AEC-Q100 Grade 0. These certifications validate its use in safety-critical automotive subsystems such as electronic throttle control and electric power steering, where failure could impact vehicle controllability.
What is the package type and pin configuration of the MLX90372GVS-ACC-303-SP?
The MLX90372GVS-ACC-303-SP uses the DMP-4 (Dual Mould Package) with Pinout-B configuration: Pin 1 = OUT, Pin 2 = VSS, Pin 3 = VDD, Pin 4 = Input (NTC/gateway). This PCB-less package integrates decoupling capacitance and is optimized for compact, high-reliability automotive modules.
Can the MLX90372GVS-ACC-303-SP be used for both rotary and linear position sensing?
Yes, the MLX90372GVS-ACC-303-SP supports both absolute rotary (0°–360°) and linear position sensing in Legacy Mode (-303 option code). Its Triaxis® Hall front end detects all three magnetic field vector components (Bx, By, Bz), allowing flexible magnet placement-rotary magnets for angle or linear magnets for displacement-without hardware change.
What is the operating temperature range of the MLX90372GVS-ACC-303-SP?
The MLX90372GVS-ACC-303-SP operates across -40°C to +160°C ambient temperature, meeting AEC-Q100 Grade 0 requirements. This range supports under-hood automotive deployment, including engine control units, transmission sensors, and suspension modules exposed to extreme thermal cycling.
