Product details
Overview
MLX90372GGO-ACE-100-RE from Melexis is a Triaxis® monolithic magnetic position processor IC for absolute rotary position sensing in stray-field-immune configurations. It features Hall-based 3-axis (Bx/By/Bz) magnetic field sensing, SENT or PWM output, AEC-Q100 qualification (-40°C to +160°C), and ISO 26262 ASIL-C Safety Element out of Context compliance. It delivers robust non-contact angular measurement in automotive throttle and pedal position systems.
For engineers reviewing the MLX90372GGO-ACE-100-RE datasheet, pinout, applications, or equivalent options, this page provides verified technical context, package-specific pin definitions, real-world application mappings, and validated alternative options for angular position sensing with stray-field immunity.
Technical Context
The MLX90372GGO-ACE-100-RE implements a dual-die TSSOP-16 architecture with full redundancy, enabling fault-tolerant operation per ISO 26262 ASIL-C requirements. Its Triaxis® front end captures all three orthogonal magnetic flux components (Bx, By, Bz), enabling precise angular decoding without mechanical contact.
This variant uses the ACE chip revision and -100 option code, configuring it for Angular Rotary Strayfield Immune mode with low-field sensitivity. It supports SAE J2716 APR2016 SENT output (3 µs tick) and programmable piecewise linear transfer characteristics (up to 32 points), with internal diagnostics including intelligent and absolute watchdogs.

| 6, 15 | OUT2 / OUT1 | Redundant digital outputs - support cross-checking or voting logic in safety-critical applications |
| 4, 5, 12, 13 | Input1 / Test2 / Input2 / Test1 | Test/application pins internally grounded - must be tied to PCB ground for EMC compliance |
| 7, 14 | N.C. | No-connect terminals - electrically isolated; no routing or soldering required |
Key Features
| Feature | Design Value |
|---|---|
| Stray-field immunity (-100 mode) | Enables reliable angular sensing in high-EMI engine compartments without external magnetic shielding |
| Dual-die TSSOP-16 redundancy | Provides hardware-level fault tolerance: independent dies allow cross-diagnostic comparison and fail-safe state activation |
| Programmable PWL transfer curve | Up to 32-point piecewise linear calibration eliminates post-assembly linearization firmware or external lookup tables |
| SENT with Secure Sensor format | Embedded CRC, status flags, and configurable diagnostic messages reduce host MCU parsing overhead and improve system-level error visibility |
| Integrated watchdog timers | Both Intelligent Watchdog (20 ms timeout) and Absolute Watchdog (20 ms) ensure deterministic recovery from software lockup or sensor freeze |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute rotary position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GDC-ACE-100-RE | SOIC-8 single-die package; no redundancy; lower pin count; lacks isolation between VSS1/VSS2 | Suitable for cost-sensitive, non-safety-critical rotary sensing where ASIL-C is not required | Select when functional safety certification is unnecessary and PCB space is constrained. |
| MLX90372GVS-ACE-100-RE | DMP-4 PCB-less package with pinout A (VSS-VDD-OUT-VSS); no test/input pins; built-in decoupling | Optimized for ultra-compact, high-volume modules where assembly cost and footprint are critical | Choose for embedded sensor subassemblies requiring minimal external passives and direct magnet coupling. |
Compared with MLX90372GGO-ACE-100-RE, the SOIC-8 variant reduces safety capability but lowers BOM cost, while the DMP-4 version trades diagnostic flexibility for miniaturization and simplified layout-neither offers the TSSOP-16's dual-die isolation or independent ground paths essential for ASIL-C decomposition.

FAQ
What is the primary magnetic sensing architecture used in the MLX90372GGO-ACE-100-RE?
The MLX90372GGO-ACE-100-RE uses Melexis' proprietary Triaxis® Hall technology, which simultaneously measures all three orthogonal components (Bx, By, Bz) of the applied magnetic flux density. This 3D sensing enables absolute angular position calculation from a single rotating magnet without mechanical contact or shielding, and is fundamental to the -100 variant's stray-field immunity in automotive applications.
Does the MLX90372GGO-ACE-100-RE support both SENT and PWM output modes?
Yes, the MLX90372GGO-ACE-100-RE supports both SENT (SAE J2716 APR2016 compliant) and PWM output protocols. Output mode selection is performed during programming via the end-user programmable memory. SENT is configured by default in factory settings and supports secure sensor formatting with CRC, status bits, and diagnostic fields; PWM is enabled as an alternative for legacy or resource-constrained host interfaces.
What safety certifications apply to the MLX90372GGO-ACE-100-RE?
The MLX90372GGO-ACE-100-RE is certified to AEC-Q100 Grade 0 (−40°C to +160°C) and qualifies as an ISO 26262 ASIL-C Safety Element out of Context (SEooC). Its dual-die TSSOP-16 implementation includes independent watchdog timers, memory ECC, and hardware-level redundancy-features documented in Melexis' Functional Safety Manual for integration into ASIL-B or ASIL-C systems.
How does the -100 option code affect the MLX90372GGO-ACE-100-RE's performance?
The -100 option code configures the MLX90372GGO-ACE-100-RE for Angular Rotary Strayfield Immune mode with low-field sensitivity. This setting optimizes magnetic front-end gain and filtering to reject interference from nearby current-carrying conductors or magnets, achieving ±0.3° typical INL accuracy in high-EMI environments such as engine bays-without requiring external shielding or recalibration.
What package type and pin count does the MLX90372GGO-ACE-100-RE use?
The MLX90372GGO-ACE-100-RE uses a TSSOP-16 RoHS-compliant surface-mount package with full hardware redundancy: two independent dies sharing one footprint. It has 16 pins-including dedicated VDD/VSS/VDEC per die, dual SENT outputs (OUT1/OUT2), and isolated test/input paths-enabling true functional safety decomposition per ISO 26262 requirements.
