Product details
Overview
MLX90372GVS-ACE-108-RE 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 compliant with SAE J2716 APR2016, operates from -40°C to +160°C, consumes 9.0–12.6 mA supply current, and uses the PCB-less DMP-4 package with Pinout-B (VDD/VSS/OUT/Input). It enables non-contacting throttle and steering wheel position sensing in automotive powertrain and chassis systems.
For engineers reviewing the MLX90372GVS-ACE-108-RE datasheet, pinout, applications, or equivalent options, this page provides verified functional context, validated DMP-4 Pinout-B terminal roles, confirmed stray-field-immune angular rotary operation, SENT 3µs mode configuration, and real-world selection guidance against comparable AEC-Q100 position processors.
Technical Context
The MLX90372GVS-ACE-108-RE implements a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, enabling robust absolute angle decoding without mechanical wear. Its on-chip DSP performs real-time signal conditioning, piecewise linear (PWL) transfer function mapping (up to 32 points), and SENT frame encoding with embedded diagnostics and 48-bit ID.
This variant is configured for Angular Rotary Strayfield Immune – Low Field Variant (-100 code), uses DMP-4 Pinout-B (Input pin enabled for NTC or analog/digital gateway), and operates in SENT 3µs mode with standard capacitor configuration (Option Code ACE-108). It supports ISO26262 ASIL-C safety element out of context and AEC-Q100 Grade 0 qualification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90371GVS-ABF-100-RE | Single-die DMP-4, SENT-only output, no Input pin, lower accuracy (±0.8°), no ASIL-C support. | Limited to cost-sensitive, non-safety-critical linear/rotary sensing where temperature compensation is handled externally. | Select when ASIL-C compliance and NTC integration are unnecessary and BOM cost is primary constraint. |
| AMS AS5055A-BQFT | 12-bit SPI/I²C output, no SENT/PWM, ±0.5° accuracy, -40°C to +125°C, SOIC-16 package. | Requires external microcontroller for protocol translation and diagnostics; unsuitable for direct ECU interfacing in ASIL-B/C domains. | Choose only if system already uses SPI/I²C infrastructure and safety architecture handles diagnostics externally. |
Compared with MLX90372GVS-ACE-108-RE, the MLX90371 offers reduced functionality and safety scope at lower cost, while the AS5055A requires host-side protocol handling and lacks automotive-grade thermal/safety certification - making MLX90372GVS-ACE-108-RE the only option supporting SENT-native, ASIL-C-ready, and NTC-integrated operation in a DMP-4 form factor.

FAQ
What is the operating temperature range of the MLX90372GVS-ACE-108-RE?
The MLX90372GVS-ACE-108-RE is rated for continuous operation from -40°C to +160°C, meeting AEC-Q100 Grade 0 requirements. This range supports under-hood placement in engine management, transmission control, and brake-by-wire systems without external thermal mitigation. The device's internal diagnostics and watchdog timers remain fully functional across this entire span.
Does the MLX90372GVS-ACE-108-RE support both SENT and PWM output protocols?
Yes, the MLX90372GVS-ACE-108-RE supports both SENT (SAE J2716 APR2016 compliant) and PWM output modes, but only one can be active at a time. This specific variant is factory-configured for SENT 3µs mode per Option Code ACE-108. PWM mode requires reprogramming via Melexis' PTC software and is not pre-enabled in the -108 configuration.
What does the "-108" in MLX90372GVS-ACE-108-RE signify?
The "-108" suffix indicates three configuration layers: "1" = Angular Rotary Strayfield Immune (Low Field Variant), "0" = SENT 3µs mode with standard capacitor configuration, and "8" = STD4 2.54 trim and form for the DMP-4 package. This combination ensures optimal performance in high-interference rotary applications with minimal external components.
Can the Input pin on the MLX90372GVS-ACE-108-RE be used for temperature sensing?
Yes - the Input pin in DMP-4 Pinout-B configuration (used by MLX90372GVS-ACE-108-RE) supports direct connection of an NTC thermistor. The IC applies a precision bias current and digitizes the voltage for on-chip temperature compensation of magnetic sensitivity and offset, eliminating the need for a separate temperature sensor or ADC channel.
Is the MLX90372GVS-ACE-108-RE certified for functional safety applications?
Yes, the MLX90372GVS-ACE-108-RE is qualified as an ISO26262 ASIL-C Safety Element out of Context (SEooC). It integrates hardware-level safety mechanisms including dual watchdogs (IWD/AWD), memory ECC, diagnostic cycle timing, and fail-safe output states - enabling its use in ASIL-B or ASIL-C systems when integrated per Melexis' safety manual.
