Product details
Overview
MLX90372GVS-ACE-300-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, AEC-Q100 qualification, and supports programmable transfer characteristics (up to 32-point PWL) in a PCB-less DMP-4 package.
For engineers reviewing the MLX90372GVS-ACE-300-SP datasheet, pinout, applications, or equivalent options, key selection criteria include stray-field immunity mode (-300), DMP-4 package pinout compatibility, SENT 3µs timing compliance per SAE J2716 APR2016, and functional safety integration for automotive pedal/throttle/steering systems.
Technical Context
The MLX90372GVS-ACE-300-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, enabling robust absolute angle decoding without mechanical contact. Its on-chip DSP performs real-time signal conditioning and piecewise linear interpolation with up to 32 breakpoints.
It supports two timing modes: asynchronous acquisition (588 µs typical measurement period) for SENT without pause and PWM, and synchronous acquisition aligned to SENT frame timing (960 µs typical frame period at 3 µs tick). Output is configurable as SENT (Secure Sensor format with error codes) or PWM with user-defined duty cycle resolution.

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-200-SP | Linear position stray-field immune variant (-200 code) - different magnetic front-end calibration and filtering | Optimized for linear stroke sensing with enhanced stray-field rejection; not interchangeable with -300 in rotary setups | Select only when linear motion dominates and external magnetic interference is present |
| MLX90372GVS-ACE-100-SP | Angular rotary stray-field immune variant (-100 code) - lower magnetic field sensitivity and dedicated low-field algorithm | Designed for low-field angular applications (e.g., small-diameter magnets); incompatible with standard magnet strengths used in -300 mode | Choose only for compact rotary designs requiring immunity to nearby current-carrying conductors |
Compared with MLX90372GVS-ACE-300-SP, the -200 variant offers superior linearity under stray fields for linear motion but lacks angular optimization, while the -100 variant trades full-range angular fidelity for enhanced noise margin in constrained magnetic environments - all share identical DMP-4 packaging and SENT/PWM interface capability.

FAQ
What is the operating temperature range of the MLX90372GVS-ACE-300-SP?
The MLX90372GVS-ACE-300-SP is rated for operation from -40°C to +160°C, meeting AEC-Q100 Grade 0 requirements. This range is validated across all electrical parameters including supply current, output timing, and angular accuracy, making it suitable for under-hood automotive deployments where thermal stress is critical. The MLX90372GVS-ACE-300-SP maintains SENT frame integrity and diagnostic functionality throughout this full range.
Does the MLX90372GVS-ACE-300-SP support both SENT and PWM outputs?
Yes, the MLX90372GVS-ACE-300-SP supports both SENT (SAE J2716 APR2016 compliant) and PWM output modes, selected via end-user programming. SENT mode delivers 48-bit ID, CRC, and diagnostic fields in Secure Sensor format; PWM mode provides configurable duty cycle resolution. The MLX90372GVS-ACE-300-SP implements both interfaces using the same DMP-4 pinout and requires no hardware changes to switch between them.
What package type does the MLX90372GVS-ACE-300-SP use, and what are its mounting advantages?
The MLX90372GVS-ACE-300-SP uses the DMP-4 (Dual Mould Package) - a PCB-less, surface-mountable package with integrated decoupling capacitance. Its STD3 2.00 mm trim & form enables direct soldering onto curved or space-constrained surfaces such as suspension components or throttle bodies. The MLX90372GVS-ACE-300-SP eliminates external capacitors and reduces assembly steps versus SOIC-8 or TSSOP-16 alternatives.
How does the MLX90372GVS-ACE-300-SP achieve ISO26262 ASIL-C compliance?
The MLX90372GVS-ACE-300-SP achieves ISO26262 ASIL-C as a Safety Element out of Context (SEooC), incorporating dual watchdog timers (IWD/AWD), memory ECC, analog diagnostics with configurable DCT, and lockstep-capable internal architecture. These mechanisms are validated per ISO26262 Part 5 Annex D and documented in Melexis' functional safety manual. The MLX90372GVS-ACE-300-SP requires no external safety monitors to fulfill ASIL-C requirements in properly architected systems.
What magnetic configurations are supported by the MLX90372GVS-ACE-300-SP in legacy mode?
In legacy (-300) mode, the MLX90372GVS-ACE-300-SP supports both absolute rotary (0–360°) and absolute linear position sensing using standard magnet arrangements - e.g., diametrically magnetized ring magnets for rotary or side-magnetized rods for linear stroke. Its Triaxis® front end resolves Bx, By, and Bz components to compute position without external concentrators. The MLX90372GVS-ACE-300-SP's factory-programmed transfer characteristic is optimized for these configurations.
