Product details
Overview
MLX90372GGO-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 programmable piecewise-linear transfer characteristics (up to 32 points), and meets AEC-Q100 Grade 0 and ISO 26262 ASIL-C as a safety element out of context. It is used in automotive pedal and throttle position sensing where robustness against external magnetic interference is critical.
For engineers reviewing the MLX90372GGO-ACE-200-RE datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, package mapping to TSSOP-16, confirmed SENT/PWM dual-output capability, validated linear stray-field immune mode (-200 option code), and real-world automotive sensor design context - all extracted from Melexis Revision 8 datasheet (Mar 2019).
Technical Context
The MLX90372GGO-ACE-200-RE implements a full Triaxis® front end sensing Bx, By, and Bz components to compute absolute angle or linear displacement without mechanical contact. Its dual-die TSSOP-16 configuration enables full redundancy with isolated analog/digital grounds (VSS1/VSS2) and independent supply/decoupling pins per die (VDD1/VDEC1 and VDD2/VDEC2).
It executes on-chip DSP-based signal conditioning including configurable FIR filtering, programmable diagnostics (AWD/IWD), and SENT frame encoding compliant with SAE J2716 APR2016. The -200 option code configures it specifically for linear position measurement with enhanced stray-field immunity, using factory-trimmed magnetic sensitivity and dedicated calibration curves.

Pinout & Package
TSSOP-16 package with full redundancy: two independent dies sharing no analog/digital power or ground domains. Pinout supports separate decoupling (VDEC1/VDEC2), supply (VDD1/VDD2), ground (VSS1/VSS2), and output (OUT1/OUT2) paths per die - enabling fault-tolerant system architectures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VDEC1 / VDEC2 | Dedicated decoupling pins per die - require local 100 nF ceramic capacitors to VSSx for noise suppression |
| 2, 10 | VSS1 / VSS2 | Isolated analog grounds per die - must be routed separately to avoid coupling faults |
| 3, 11 | VDD1 / VDD2 | Independent supply inputs per die - enable dual-rail monitoring and fail-safe shutdown |
| 6, 15 | OUT2 / OUT1 | Redundant digital outputs - support cross-checking or voting logic in safety-critical systems |
| 4, 12 | Input1 / Input2 | Configurable gateway pins - usable for NTC biasing or auxiliary analog/digital input in custom firmware |
| 5, 13 | Test2 / Test1 | Factory test interfaces - internally grounded in application; connect to PCB ground for EMC |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90371GGO-ABD-200-RE | Single-die TSSOP-16; lacks dual-die redundancy and ASIL-C SEooC certification | Suitable for non-safety-critical linear position tasks (e.g., HVAC damper control) but not ASIL-B/C systems | Select only when functional safety certification is not required and cost optimization is prioritized |
| AMS AS5600-WSCT | Single-die SOIC-8; I²C interface only; no SENT/PWM; ±0.5° accuracy; no stray-field immunity | Used in consumer-grade rotary encoders or low-cost industrial knobs - lacks automotive qualification and EMI hardening | Choose for space-constrained designs needing I²C bus integration, not for automotive linear sensing |
Compared with MLX90372GGO-ACE-200-RE, the MLX90371 alternative omits redundancy and safety certification, while the AS5600 lacks SENT output, stray-field immunity, and AEC-Q100 qualification - making neither suitable as drop-in replacements in ASIL-C pedal or throttle systems.

FAQ
What is the primary function of the MLX90372GGO-ACE-200-RE in automotive systems?
The MLX90372GGO-ACE-200-RE functions as a stray-field immune linear position sensor for absolute displacement measurement. It uses Triaxis® Hall technology to decode magnet motion into precise SENT or PWM output signals. In automotive systems, it directly replaces contacting potentiometers in pedal and throttle assemblies, providing wear-free, high-accuracy feedback with built-in diagnostics and ASIL-C safety compliance - all confirmed in Melexis datasheet Rev. 8 (2019).
Does the MLX90372GGO-ACE-200-RE support both SENT and PWM output simultaneously?
No, the MLX90372GGO-ACE-200-RE supports either SENT or PWM output - selected during programming via the Output Mode parameter. It cannot output both protocols concurrently. The SENT implementation complies with SAE J2716 APR2016 and includes Secure Sensor features like CRC, status flags, and user-defined payload. PWM mode offers configurable frequency and duty-cycle mapping to position - both modes are validated for the -200 linear stray-field immune configuration.
What does the "-200" option code signify for the MLX90372GGO-ACE-200-RE?
The "-200" option code configures the MLX90372GGO-ACE-200-RE for Linear Position Strayfield Immune operation. This activates factory-trimmed magnetic sensitivity, dedicated calibration curves, and optimized front-end filtering to reject orthogonal interfering fields up to ±1 T. It is distinct from -100 (rotary stray-field immune) and -300 (legacy angular/linear) variants - and is explicitly documented in Table 8 (Magnetic Field Specifications) and Section 8.3 of the datasheet.
How is functional safety implemented in the MLX90372GGO-ACE-200-RE?
The MLX90372GGO-ACE-200-RE implements functional safety as an ISO 26262 ASIL-C Safety Element out of Context (SEooC). It includes dual watchdogs (Intelligent Watchdog TIWD = 20 ms, Absolute Watchdog TAWD = 20 ms), memory ECC, diagnostic cycle timing (DCTANA/DCTDIG), and fail-safe state activation within 11.9–34.6 ms after fault detection. These mechanisms are hardware-enforced and validated per Melexis Safety Manual (Rev. 8, Section 14), with no software dependency required for basic safety functionality.
What package type does the MLX90372GGO-ACE-200-RE use, and why is it significant?
The MLX90372GGO-ACE-200-RE uses the TSSOP-16 package (GO code), which houses two fully redundant dies with isolated power, ground, and signal paths. This physical separation - confirmed by >4 MΩ isolation resistance between VSS1 and VSS2 - enables fault containment and voting architectures required for ASIL-C systems. Unlike SOIC-8 or DMP-4 variants, the TSSOP-16 supports true hardware redundancy, making it mandatory for safety-critical pedal and throttle applications per ISO 26262.
