Product details
Overview
MLX90372GGO-ACC-500-SP from Melexis is a Triaxis® monolithic magnetic position processor IC for absolute rotary and linear position sensing. It integrates a 3-axis Hall front end, DSP-based signal conditioning, and SENT or PWM output. Operating from -40°C to +160°C with AEC-Q100 qualification and ISO 26262 ASIL-C safety compliance, it delivers robust stray-field immune angular position measurement in automotive throttle and pedal applications.
For engineers reviewing the MLX90372GGO-ACC-500-SP datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (TSSOP-16), confirmed dual-die redundancy architecture, SENT v4.0/SAE J2716 APR2016 compliance, ±0.3° typical angular accuracy in high-field rotary mode, and validated alternative options for ASIL-C–compliant position sensing designs.
Technical Context
The MLX90372GGO-ACC-500-SP implements a full-redundant dual-die architecture in TSSOP-16 packaging, with isolated analog/digital grounds (VSS1/VSS2) and independent supply/decoupling pins per die (VDD1/VDEC1 and VDD2/VDEC2). Its Triaxis® Hall sensor measures Bx, By, and Bz components to compute absolute angle without mechanical contact.
It supports two timing modes: asynchronous acquisition (588 µs typical measurement period) for SENT without pause or PWM, and synchronous acquisition locked to SENT frame timing (960 µs typical frame period at 3 µs tick). Output is configurable as SENT (SAE J2716 APR2016) or PWM, with programmable transfer characteristics using up to 32-point PWL.

Pinout & Package
TSSOP-16 package with full-redundant dual-die construction, RoHS-compliant, thermal pad optional (see Melexis Package Drawing GO).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VDEC1 / VDEC2 | Dedicated decoupling pins per die - Requires separate 100 nF ceramic capacitors to ground for stable analog regulation. |
| 2, 10 | VSS1 / VSS2 | Separate analog grounds per die - Must be routed independently to minimize crosstalk in redundant signal paths. |
| 3, 11 | VDD1 / VDD2 | Independent supply inputs per die - Enables fault detection via supply monitoring on each channel. |
| 6, 15 | OUT2 / OUT1 | Redundant digital outputs - Supports cross-checking or fail-safe voting logic in safety-critical systems. |
| 4, 12 | Input1 / Input2 | Configurable test/application pins - Internally grounded in operation; connect to PCB ground for EMC compliance. |
| 5, 13 | Test2 / Test1 | Factory test access - Not user-accessible in final application; tie to ground per datasheet recommendation. |
| 7, 14 | N.C. | No internal connection - Must remain unconnected; avoid routing traces or vias. |
| 8, 16 | VSS2 / VSS1 | Digital grounds per die - Shared with respective VSS1/VSS2 analog grounds only at single-point system ground. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GGO-ACE-500-RE | ACE revision replaces ACC; improved startup timing (TSafeStup ≤12.4 ms vs. not specified for ACC), enhanced ESD robustness. | Same TSSOP-16 package, -500 high-field rotary mode, SENT/PWM output - Direct drop-in for new designs requiring latest silicon revision. | Select ACE-500 for new designs to ensure long-term availability and access to updated safety manual (Rev. 8+). |
| MLX90371GGO-ACE-500-RE | Single-die version in same TSSOP-16 package; lacks dual-die isolation and ASIL-C SEooC certification. | Lower cost, no functional redundancy - Suitable for non-safety-critical industrial linear/rotary sensing where ASIL-C is not mandated. | Choose MLX90371 only when safety certification and hardware redundancy are unnecessary; not suitable for automotive ASIL-B/C systems. |
Compared with MLX90372GGO-ACC-500-SP, the ACE-500 alternative offers guaranteed lifecycle support and tighter startup timing, while the MLX90371GGO-ACE-500-RE reduces cost and complexity at the expense of ASIL-C compliance and dual-die fault tolerance.

FAQ
What is the primary function of the MLX90372GGO-ACC-500-SP?
The MLX90372GGO-ACC-500-SP is a Triaxis® monolithic magnetic position processor IC that computes absolute angular or linear position from 3-axis Hall measurements. It outputs calibrated position data via SENT or PWM protocols and is specifically configured in the -500 option code for high-field rotary applications with enhanced stray-field immunity. This makes MLX90372GGO-ACC-500-SP ideal for automotive throttle and pedal sensing where precision and EMI resilience are critical.
Does the MLX90372GGO-ACC-500-SP support functional safety standards?
Yes, the MLX90372GGO-ACC-500-SP is certified to ISO 26262 ASIL-C as a Safety Element out of Context (SEooC) and qualified to AEC-Q100 Grade 0. Its dual-die TSSOP-16 implementation provides hardware-level redundancy, and its integrated diagnostics-including CRC, watchdog timers, and supply monitoring-enable seamless integration into ASIL-B or ASIL-C systems. These features are fully documented in the MLX90372GGO-ACC-500-SP safety manual (Rev. 8).
What package type and pin count does the MLX90372GGO-ACC-500-SP use?
The MLX90372GGO-ACC-500-SP uses the TSSOP-16 package with full-redundant dual-die construction. It has 16 pins, including duplicated supply (VDD1/VDD2), ground (VSS1/VSS2), decoupling (VDEC1/VDEC2), and output (OUT1/OUT2) terminals to support independent operation of each die. Pin definitions are explicitly defined in Section 3.2 of the MLX90372GGO-ACC-500-SP datasheet, and unused pins (7, 14) are marked N.C.
Can the MLX90372GGO-ACC-500-SP output both SENT and PWM signals simultaneously?
No, the MLX90372GGO-ACC-500-SP supports either SENT or PWM output-not both simultaneously. The output protocol is selected during programming via the OUTPUT_MODE parameter (Section 13.1). SENT follows SAE J2716 APR2016 with Secure Sensor format, while PWM offers configurable frequency and duty cycle. The MLX90372GGO-ACC-500-SP's output stage is designed for single-mode operation to ensure timing integrity and diagnostic coverage.
What is the meaning of "-500" in the MLX90372GGO-ACC-500-SP part number?
The "-500" suffix in MLX90372GGO-ACC-500-SP denotes the high-field rotary stray-field immune configuration. Per Table 2 and Section 8.2 of the datasheet, this option code enables operation in magnetic fields up to ±50 mT with ±0.3° typical angular accuracy, optimized for throttle and steering applications near high-current actuators. It is distinct from -100 (low-field rotary), -200 (linear), and -300 (legacy) variants-all sharing the same MLX90372GGO-ACC-500-SP silicon but differing in factory-programmed magnetic sensitivity and transfer characteristics.
