Product details
Overview
MLX90372GGO-ACE-200-SP 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, features ISO26262 ASIL-C safety compliance, and supports programmable piecewise-linear transfer characteristics up to 32 points. 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-SP datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (TSSOP-16), confirmed stray-field immune linear mode operation (-200 option code), SENT v4.0 timing compliance, AEC-Q100 qualification, and functional safety architecture details required for automotive sensor design and qualification.
Technical Context
The MLX90372GGO-ACE-200-SP implements dual-die full-redundant architecture in TSSOP-16 package with isolated analog grounds (VSS1/VSS2) and decoupling pins (VDEC1/VDEC2). Its Triaxis® front end measures Bx, By, and Bz components simultaneously to compute absolute linear displacement without mechanical contact.
It operates in Stray-field Immune Linear Mode (option -200), configured via factory-programmed memory to reject orthogonal magnetic interference while maintaining ±0.3° angular accuracy and <±1.5% INL over full range. Output is SENT SAE J2716 APR2016 compliant with 3µs tick time and enhanced error reporting.
Key Specifications

| Supply Voltage | 4.5 V to 5.5 V - Compatible with regulated 5 V automotive domains; supports battery mode up to 18 V via configuration. |
| Supply Current | 8.0–10.5 mA - Dual-die current draw is doubled; optimized for low-power linear position sensing in continuous mode. |
| Output Protocol | SENT APR2016 or PWM - SENT frame includes 48-bit ID, diagnostics, and user-defined values; PWM supports duty-cycle encoding. |
| Accuracy (INL) | <±1.5% - Validated for linear position applications per option -200 specification; enables high-fidelity pedal travel measurement. |
| Safety Certification | ISO26262 ASIL-C SEooC - Delivers safety element out of context for integration into ASIL-B/C systems without additional hardware redundancy. |
| Magnetic Immunity | Stray-field immune linear mode - Rejects orthogonal magnetic fields up to ±10 mT; eliminates need for external shielding in chassis-mounted sensors. |
Pinout & Package
TSSOP-16 package with full redundancy: two independent dies, isolated power/ground domains, and separate output channels (OUT1/OUT2) for fault-tolerant architectures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VDEC1 / VDEC2 | Dedicated decoupling pins per die - Require local 100 nF ceramic capacitors to stabilize internal 3.3 V analog regulator. |
| 2, 10, 16 | VSS1 / VSS2 / VSS1 | Isolated analog/digital ground domains - Prevent coupling between signal paths; mandatory separation on PCB layout. |
| 3, 11 | VDD1 / VDD2 | Independent supply inputs per die - Enable dual-rail monitoring and fail-safe power domain isolation. |
| 6, 15 | OUT2 / OUT1 | Redundant SENT/PWM outputs - Support cross-checking or voting logic in safety-critical control units. |
| 4, 5, 12, 13 | Input1 / Test2 / Input2 / Test1 | Factory-test and diagnostic access - Internally grounded in application; connect to PCB ground for EMC compliance. |
| 7, 14 | N.C. | No internal connection - Must be left unconnected or tied to ground per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Simultaneous Bx/By/Bz measurement enables true absolute linear position decoding without rotational ambiguity or homing sequence. |
| Programmable PWL Transfer | Up to 32-point piecewise-linear calibration allows precise compensation of mechanical nonlinearity in lever-arm or slider mechanisms. |

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-SP | Single-die TSSOP-16, no ASIL-C certification, SENT only (no PWM), lower INL (±2.0%) | Lacks dual-die redundancy and functional safety evidence; suitable for non-safety-critical industrial linear sensing. | Select when cost sensitivity outweighs ASIL-C requirement and diagnostic depth. |
| AMS AS5055A-BQFT | Single-die TSSOP-16, SPI/I²C interface only, no SENT/PWM, ±0.5° typical accuracy, no stray-field immunity mode | Requires external microcontroller for protocol translation; not qualified to AEC-Q100 Grade 0. | Choose for SPI-based embedded systems needing higher angular resolution but accepting added software complexity and no automotive qualification. |
Compared with MLX90372GGO-ACE-200-SP, the MLX90371 alternative reduces cost and power but sacrifices safety certification and redundancy, while the AS5055A requires host MCU intervention and lacks magnetic immunity - making the MLX90372GGO-ACE-200-SP uniquely suited for ASIL-B/C linear position sensing in harsh automotive environments.

FAQ
What is the operating temperature range of the MLX90372GGO-ACE-200-SP?
The MLX90372GGO-ACE-200-SP operates from -40°C to +160°C, validated per AEC-Q100 Grade 0 requirements. This range supports under-hood placement in modern ICE and EV powertrains, including proximity to exhaust manifolds and motor inverters. The TSSOP-16 package's thermal resistance (RθJA = 52°C/W) ensures junction temperature remains within safe limits at 10.5 mA supply current under worst-case ambient conditions.
Does the MLX90372GGO-ACE-200-SP support both SENT and PWM output modes?
Yes, the MLX90372GGO-ACE-200-SP supports both SENT SAE J2716 APR2016 and PWM output protocols, selectable via end-user programming. In SENT mode, it delivers 48-bit ID, diagnostics, and user data in secure format; in PWM mode, it encodes position as duty cycle with configurable frequency. Both modes are active simultaneously on OUT1 and OUT2 in TSSOP-16 package, enabling redundant signal paths.
How does the -200 option code affect the MLX90372GGO-ACE-200-SP's magnetic performance?
Option code -200 configures the MLX90372GGO-ACE-200-SP for Stray-field Immune Linear Mode, optimizing its Triaxis® front end to reject orthogonal magnetic interference up to ±10 mT while maintaining <±1.5% INL for linear displacement. This eliminates need for external mu-metal shielding in pedal or suspension sensors mounted near motors or solenoids, reducing system cost and size.
Is the MLX90372GGO-ACE-200-SP certified for functional safety applications?
Yes, the MLX90372GGO-ACE-200-SP is certified as an ISO26262 ASIL-C Safety Element out of Context (SEooC), with documented safety mechanisms including lockstep DSP monitoring, memory ECC, watchdog timers (IWD/AWD), and diagnostic coverage >90%. It provides all necessary safety artifacts - FMEDA, safety manual, and HW-SW interface definition - for integration into ASIL-B or ASIL-C systems without additional hardware redundancy.
What package type and pin count does the MLX90372GGO-ACE-200-SP use?
The MLX90372GGO-ACE-200-SP uses a TSSOP-16 package with full dual-die redundancy. It contains two independent sensor dies, each with dedicated VDD, VSS, VDEC, and OUT pins (pins 1–3, 6, 8–11, 15–16), plus test/input pins (4, 5, 12, 13) and N.C. terminals (7, 14). This layout enables fault-isolated operation and meets automotive EMC requirements when routed with split ground planes.
