Product details
Overview
MLX90372GVS-ACE-308-RX 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 certification, and uses a PCB-less DMP-4 package with Pinout-B configuration for NTC/analog gateway support in automotive throttle and pedal sensors.
For engineers reviewing the MLX90372GVS-ACE-308-RX datasheet, pinout, applications, or equivalent options, this page provides verified functional context, validated DMP-4 Pinout-B terminal roles, confirmed SENT/PWM timing modes, stray-field-immune angular/linear measurement capability, and AEC-Q100 qualification status.
Technical Context
The MLX90372GVS-ACE-308-RX implements Triaxis® Hall sensing to resolve all three magnetic field vector components (Bx, By, Bz), enabling robust absolute angle or displacement decoding without mechanical contact. Its on-chip DSP supports programmable piecewise-linear (PWL) transfer characteristics with up to 32 points and configurable SENT frame structure per SAE J2716 APR2016.
This variant uses the ACE chip revision in DMP-4 package with Pinout-B (OUT/VSS/VDD/Input), where Input serves as NTC or analog/digital gateway interface. It operates in legacy/standard mode (-300 option code), supports both asynchronous and synchronous acquisition timing, and includes integrated diagnostics with intelligent watchdog (TIWD = 20 ms) and fail-safe state activation.

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-308-RX | Single-die architecture; no ASIL-C certification; SENT-only output; lower accuracy (±0.5°) | Limited to non-safety-critical applications like HVAC dampers or seat position | Select when cost sensitivity outweighs functional safety requirements and diagnostic depth |
| AMS AS5055A-BQFT | Rotary-only Hall encoder; SPI/I²C interface; no SENT/PWM; ±0.25° accuracy; no AEC-Q100 Grade 0 | Suitable for infotainment rotary knobs or non-automotive industrial encoders | Choose for SPI-based systems requiring higher resolution but lacking automotive qualification or stray-field immunity |
Compared with MLX90372GVS-ACE-308-RX, MLX90371GVS-ABF-308-RX lacks ASIL-C and offers reduced diagnostics, while AMS AS5055A-BQFT provides higher angular resolution but omits SENT output, automotive qualification, and stray-field resilience-making MLX90372GVS-ACE-308-RX uniquely suited for safety-critical, magnetically noisy automotive position sensing.

FAQ
What is the package type and pin configuration of MLX90372GVS-ACE-308-RX?
The MLX90372GVS-ACE-308-RX uses the DMP-4 (Dual Mould Package) with Pinout-B configuration: Pin 1 = OUT, Pin 2 = VSS, Pin 3 = VDD, Pin 4 = Input. This layout supports NTC thermistor integration or analog/digital gateway functions and is PCB-less, reducing assembly complexity. The "RX" suffix indicates tape-and-reel packaging with face-down orientation specific to DMP-4 devices.
Does MLX90372GVS-ACE-308-RX support both SENT and PWM output modes?
Yes, MLX90372GVS-ACE-308-RX supports both SENT (SAE J2716 APR2016 compliant) and PWM output modes, configurable via end-user programming. SENT mode offers secure sensor format with 48-bit ID and CRC, while PWM provides deterministic timing for legacy ECUs. The device defaults to SENT 3 µs mode per its ACE-308 option code, and switching requires reprogramming using Melexis' PTC software tool.
What safety certifications apply to MLX90372GVS-ACE-308-RX?
MLX90372GVS-ACE-308-RX 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 suitability for automotive safety-related systems such as electronic throttle control and brake-by-wire, with documented safety mechanisms including watchdog timers, memory ECC, and diagnostic cycle monitoring per the official Melexis safety manual.
How does the MLX90372GVS-ACE-308-RX achieve stray magnetic field immunity?
The MLX90372GVS-ACE-308-RX achieves stray-field immunity through Triaxis® Hall technology combined with on-chip differential signal processing and proprietary magnetic front-end filtering. In standard (-300) mode, it maintains angular accuracy within ±0.3° even under external DC or AC magnetic interference up to ±100 Gauss, eliminating need for external shielding in applications like engine bay throttle sensors or EPS motor proximity installations.
What is the operating temperature range and supply voltage specification for MLX90372GVS-ACE-308-RX?
MLX90372GVS-ACE-308-RX operates from -40°C to +160°C and supports dual supply modes: regulated 4.5–5.5 V (for 5 V systems) or battery-rail 6–18 V (for direct battery connection). Internal regulation generates a stable 3.3 V analog rail (VDEC), and undervoltage/overvoltage detection thresholds are programmable to match system-level power architecture requirements.
