Product details
Overview
MLX90372GVS-ACE-200-RE from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute linear position sensing with stray-field immunity. It delivers SENT or PWM output, operates from -40°C to +160°C, supports 4.5–5.5 V regulated supply (or 6–18 V battery), and is AEC-Q100 qualified for automotive pedal and throttle position sensing.
For engineers reviewing the MLX90372GVS-ACE-200-RE datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DMP-4 Pinout B), confirmed stray-field immune linear mode operation, SENT/PWM timing specs, ISO26262 ASIL-C safety compliance, and real-world design context for non-contacting position feedback in harsh environments.
Technical Context
The MLX90372GVS-ACE-200-RE implements a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, enabling robust absolute linear position decoding without mechanical wear. Its on-chip DSP performs real-time signal conditioning, piecewise linear (PWL) transfer function correction (up to 32 points), and programmable diagnostics.
This variant uses DMP-4 package with Pinout B (VSS/VDD/OUT/Input), where Input serves as NTC or analog/digital gateway. It is configured for Linear Stray-field Immune Mode (-200 option code), delivering ±0.5° angular accuracy or ≤1.5% FS linearity over full stroke, with SENT frames compliant to SAE J2716 APR2016.

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-200-RE | Legacy Triaxis® device with fixed 16-point PWL, no SENT support - only PWM output | Lacks SENT protocol, diagnostics, and ASIL-C certification; limited to non-safety-critical linear sensing | Select when cost sensitivity outweighs diagnostic depth and functional safety requirements |
| AMS AS5600-WSCT | Single-die Hall angle sensor with I²C output; no stray-field immunity or ASIL qualification | Designed for consumer-grade rotary encoders; lacks automotive qualification, temperature range, and linear mode capability | Consider only for non-automotive, low-EMI, rotary-only applications with I²C host interface |
Compared with MLX90372GVS-ACE-200-RE, the MLX90371 offers lower system cost but sacrifices SENT diagnostics and ASIL-C compliance, while the AS5600 lacks automotive qualification, stray-field resilience, and linear position capability - making MLX90372GVS-ACE-200-RE uniquely suited for safety-critical, magnetically noisy linear sensing.

FAQ
What is the primary magnetic sensing architecture used in the MLX90372GVS-ACE-200-RE?
The MLX90372GVS-ACE-200-RE employs Melexis' proprietary Triaxis® Hall technology, which simultaneously measures all three orthogonal components (Bx, By, Bz) of the applied magnetic field. This enables precise absolute linear position decoding without mechanical contact, and is fundamental to its stray-field immunity in Linear Stray-field Immune Mode (-200 option code). The architecture is implemented in a single die within the DMP-4 package.
Does the MLX90372GVS-ACE-200-RE support both SENT and PWM outputs, and how is the selection made?
Yes, the MLX90372GVS-ACE-200-RE supports both SENT (SAE J2716 APR2016 compliant) and PWM outputs. Selection is performed via end-user programming of the Output Mode parameter (see Section 13.1 of the datasheet); no hardware change is required. The SENT interface provides enhanced diagnostics and error reporting, while PWM offers deterministic timing and analog-equivalent simplicity for legacy ECU interfaces.
What does the "-200" in the MLX90372GVS-ACE-200-RE part number indicate?
The "-200" suffix in MLX90372GVS-ACE-200-RE specifies Linear Stray-field Immune Mode - a factory-programmed configuration that optimizes the IC's magnetic front-end and signal processing for high-accuracy absolute linear position sensing in environments with strong external magnetic interference (e.g., near motors or high-current conductors). It guarantees ≤1.5% FS linearity and robustness against >10 mT stray fields.
Is the MLX90372GVS-ACE-200-RE qualified for automotive safety applications, and what level does it achieve?
Yes, the MLX90372GVS-ACE-200-RE is certified as an ISO26262 ASIL-C Safety Element out of Context (SEooC) and is AEC-Q100 Grade 0 qualified (-40°C to +160°C). As a SEooC, it provides documented safety mechanisms (e.g., watchdogs, memory ECC, diagnostic cycles) that can be integrated into higher-level ASIL-B or ASIL-C systems when combined with appropriate system-level safety measures.
What is the package type and pin configuration of the MLX90372GVS-ACE-200-RE, and how does it differ from SOIC-8 versions?
The MLX90372GVS-ACE-200-RE uses the DMP-4 (Dual Mould Package) with Pinout B: a 4-pin, PCB-less surface-mount package where pins are assigned as OUT, VSS, VDD, and Input (NTC/gateway). Unlike SOIC-8 variants, it integrates decoupling capacitance, eliminates PCB routing complexity, and supports direct module-level assembly - reducing bill-of-materials and improving EMC performance in space-constrained automotive modules.
