Product details
Overview
MLX90372GVS-ACE-108-SP from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute rotary position sensing in stray-field-immune configurations. It delivers SENT output (3µs tick, Pinout-B), operates from -40°C to +160°C, supports programmable linear transfer characteristic (16-point PWL), and features ISO26262 ASIL-C safety element out of context compliance. It is used in automotive throttle and steering wheel position sensing where robustness against external magnetic interference is critical.
For engineers reviewing the MLX90372GVS-ACE-108-SP datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DMP-4, Pinout-B), confirmed SENT timing (3µs mode), validated stray-field immunity for angular rotary use, and real-world diagnostic cycle time (20 ms digital DCT) - all essential for functional safety validation and ECU interface design.
Technical Context
The MLX90372GVS-ACE-108-SP implements a Triaxis® Hall front end sensitive to Bx, By, and Bz components, enabling precise 360° absolute angle decoding from a single moving magnet. Its on-chip DSP performs real-time signal conditioning, including exponential moving average (EMA) filtering and piecewise linear (PWL) transfer function interpolation with up to 16 breakpoints.
This variant uses DMP-4 package with Pinout-B (OUT/VSS/VDD/Input), where the Input pin serves as NTC or analog/digital gateway - a configuration exclusive to ACE-1xx codes. It operates in continuous asynchronous acquisition mode (TangleMeas = 588 µs typical) and outputs SAE J2716 APR2016 SENT frames with embedded diagnostics, CRC, and 48-bit ID support.

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-100-SP | Same DMP-4 Pinout-B package and SENT 3µs mode, but uses standard capacitor configuration (vs. config #2 in -108) | Identical stray-field immune angular rotary functionality; differs only in internal decoupling capacitor layout | Select -100 for legacy designs; -108 adds optimized capacitor configuration for enhanced EMC in high-noise chassis domains |
| MLX90371GVS-ABE-100-SP | Single-die predecessor; lacks ASIL-C SEooC certification and 48-bit ID; supports only 4/8-point PWL | Not suitable for new ASIL-B/C designs; limited diagnostic coverage and lower accuracy (±0.5°) | Only consider for cost-sensitive, non-safety-critical industrial applications where functional safety is not required |
Compared with MLX90372GVS-ACE-108-SP, the -100 variant offers identical core sensing and safety features but omits the enhanced capacitor configuration for EMC robustness, while the MLX90371 lacks ASIL-C qualification, 48-bit ID, and advanced 16-point linearization - making the -108 the preferred choice for new automotive safety-critical designs requiring full SAE J2716 APR2016 compliance and stray-field resilience.

FAQ
What output protocol does the MLX90372GVS-ACE-108-SP support?
The MLX90372GVS-ACE-108-SP supports SENT per SAE J2716 APR2016 with 3 µs tick time and is configured for Pinout-B (OUT/VSS/VDD/Input). It does not support PWM in this option code; PWM capability requires different ACE-xxx configuration. The SENT output includes embedded diagnostics, CRC, and a 48-bit unique ID - all accessible without external programming hardware.
Is the MLX90372GVS-ACE-108-SP qualified for automotive safety applications?
Yes, the MLX90372GVS-ACE-108-SP is certified as an ISO26262 ASIL-C Safety Element out of Context (SEooC) and AEC-Q100 Grade 0 qualified. It integrates hardware-level safety mechanisms including dual watchdogs (IWD/AWD), memory ECC, and diagnostic cycle monitoring (DCTDIG = 20 ms), enabling its use as a primary sensor in ASIL-B and ASIL-C systems such as electronic throttle control and EPS.
What is the purpose of the Input pin on the MLX90372GVS-ACE-108-SP?
The Input pin on the MLX90372GVS-ACE-108-SP (Pinout-B) functions as an NTC or analog/digital gateway input. It allows direct connection of a thermistor for temperature compensation of magnetic sensitivity or serves as a configurable digital input for auxiliary signals - enabling single-package integration of position and thermal sensing without external ADC or GPIO expansion.
How does stray-field immunity work in the MLX90372GVS-ACE-108-SP?
The MLX90372GVS-ACE-108-SP achieves stray-field immunity through proprietary Triaxis® signal processing that rejects common-mode magnetic interference while preserving the orthogonal field components (Bx, By, Bz) needed for angle calculation. In -100-code variants like this one, it maintains ±0.3° accuracy under external stray fields up to 1 mT - validated per ISO11452-8 - eliminating the need for magnetic shielding in engine compartment deployments.
What package type and pin configuration does the MLX90372GVS-ACE-108-SP use?
The MLX90372GVS-ACE-108-SP uses the DMP-4 (Dual Mould Package) with Pinout-B configuration: Pin 1 = OUT, Pin 2 = VSS, Pin 3 = VDD, Pin 4 = Input. This PCB-less, leadless package is optimized for automated assembly into compact automotive sensor modules and supports both SENT and auxiliary signal routing within a 2.54 mm pitch STD4 trim form.
