Product details
Overview
MLX90372GGO-ACE-300-SP from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute rotary and linear position sensing. It features on-chip DSP signal conditioning, SENT or PWM output (SAE J2716 APR2016 compliant), ISO26262 ASIL-C safety element out of context, AEC-Q100 qualification, and operates from −40°C to +160°C in TSSOP-16 package.
For engineers reviewing the MLX90372GGO-ACE-300-SP datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, validated pin definitions for dual-die TSSOP-16, real-world automotive use cases, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The MLX90372GGO-ACE-300-SP implements a full dual-die redundant architecture in TSSOP-16, with isolated analog grounds (VSS1/VSS2), independent supply rails (VDD1/VDD2), and separate decoupling pins (VDEC1/VDEC2). Its Triaxis® front end measures all three magnetic field components (Bx, By, Bz) to compute absolute angular or linear position without mechanical contact.
It supports programmable transfer characteristics (4/8/16/32-point PWL), SENT 3µs mode with Secure Sensor format (48-bit ID option), and configurable diagnostics including intelligent watchdog (TIWD = 20 ms) and fail-safe state duration (TFSS = 9.8–34.6 ms). The -300 option code specifies legacy angular/linear mode with no stray-field immunity enhancement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | −40°C to +160°C - qualified for under-hood automotive environments |
| Supply Voltage | 4.5 V to 5.5 V - regulated mode; supports battery operation up to 18 V via PTC detection |
| Supply Current | 8.0–10.5 mA - for legacy (-300) applications; doubled for dual-die TSSOP-16 |
| Output Protocol | SENT (SAE J2716 APR2016) or PWM - selectable via programming; SENT includes error codes and user-defined values |
| Safety Certification | ISO26262 ASIL-C SEooC - enables integration into ASIL-B/C systems without additional hardware redundancy |
| Accuracy | ±0.3° typical angular error - specified for standard/legacy (-300) mode at 25°C |
| Magnetic Range | ±1 T maximum flux density - robust against external stray fields per design |
Pinout & Package
TSSOP-16 package (GO code) houses two fully redundant dies for functional safety compliance. Pinout supports independent power, ground, and output paths per die, enabling true hardware-level fault tolerance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VDEC1 / VDEC2 | Dedicated decoupling pins per die - require local 100 nF ceramic capacitors to VSS |
| 2, 10, 16 | VSS1 / VSS2 / VSS1 | Isolated analog/digital grounds - VSS1 and VSS2 are electrically separated (Risol ≥ 4 MΩ) |
| 3, 11 | VDD1 / VDD2 | Independent supply inputs per die - enable dual-rail monitoring and fault isolation |
| 6, 15 | OUT2 / OUT1 | Separate digital outputs per die - support cross-checking or voting logic in safety-critical systems |
| 4, 5, 12, 13 | Input1 / Test2 / Input2 / Test1 | Test/application pins - internally grounded in production; connect to PCB ground for EMC |
| 7, 14 | N.C. | No internal connection - must be left unconnected or tied to ground per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Dual-die TSSOP-16 redundancy | Full hardware redundancy with isolated power, ground, and signal paths - meets ASIL-C requirements without external components |
| Triaxis® 3D magnetic sensing | Simultaneous Bx, By, Bz measurement enables absolute angle decoding from 0° to 360° or linear displacement without magnet rotation |
| Programmable transfer curve | Configurable 4-, 8-, 16-, or 32-point piecewise linear (PWL) mapping - eliminates external calibration circuitry |
| SENT Secure Sensor protocol | 48-bit ID, CRC, and diagnostic data embedded in frame - enables traceability and real-time fault reporting in ECU networks |
| Stray-field immune variants | Not enabled in -300 option - this part uses standard legacy magnetic configuration optimized for cost-sensitive angular/linear applications |
Applications
| Steering Wheel Position Sensing | Pedal Position Sensing |
|---|---|
Use Scenario: Non-contact measurement of steering column rotation in EPS systems with high EMC immunity and thermal stability. IC Role / Device Role / Timing Role: Absolute angular position processor delivering SENT frames at 10 kHz update rate with fail-safe state activation on fault detection. Use Value: Eliminates potentiometer wear and contact bounce; dual-die architecture ensures continuous operation during single-point failures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GDC-ACE-300-RE | SOIC-8 single-die package; no electrical isolation between grounds; lower pin count; 3000 pcs/reel | Lacks dual-die redundancy and ASIL-C SEooC certification; suitable for non-safety-critical linear/rotary sensing | Select when cost, board space, or functional safety level < ASIL-B is acceptable |
| MLX90372GVS-ACE-300-RX | DMP-4 PCB-less package with Pinout-B; integrated capacitors; face-down tape-and-reel; 2500 pcs/reel | Optimized for ultra-compact mounting on flexible substrates; no external decoupling required; not pin-compatible with TSSOP-16 | Select for space-constrained modules where solder joint reliability and EMI performance outweigh need for test access |
Compared with MLX90372GGO-ACE-300-SP, the SOIC-8 variant reduces cost and footprint but forfeits functional safety capability, while the DMP-4 version trades testability and layout flexibility for miniaturization and built-in filtering - all three share identical core sensing functionality and -300 magnetic configuration.

FAQ
What is the package type and pin count of the MLX90372GGO-ACE-300-SP?
The MLX90372GGO-ACE-300-SP uses a TSSOP-16 package with 16 leads. This dual-die configuration provides electrically isolated grounds (VSS1/VSS2), independent supplies (VDD1/VDD2), and separate outputs (OUT1/OUT2) to meet ISO26262 ASIL-C requirements. Pin definitions are fully documented in Section 3.2 of the official datasheet revision 8.
Does the MLX90372GGO-ACE-300-SP support SENT or PWM output?
Yes, the MLX90372GGO-ACE-300-SP supports both SENT (SAE J2716 APR2016 compliant) and PWM output modes, selectable via end-user programming. SENT mode delivers secure frames with CRC, error codes, and optional 48-bit ID; PWM mode provides pulse-width modulated signals with configurable frequency and duty cycle. Both are supported in the -300 option code.
What safety certifications apply to the MLX90372GGO-ACE-300-SP?
The MLX90372GGO-ACE-300-SP is certified as an ISO26262 ASIL-C Safety Element out of Context (SEooC) and qualified to AEC-Q100 Grade 0 (−40°C to +160°C). These certifications validate its suitability for integration into ASIL-B and ASIL-C automotive systems without requiring additional hardware redundancy, provided system-level integration follows Melexis' safety manual.
What magnetic configuration does the "-300" option code indicate for the MLX90372GGO-ACE-300-SP?
The "-300" option code in MLX90372GGO-ACE-300-SP denotes the legacy/standard magnetic configuration supporting both angular rotary and linear position sensing without enhanced stray-field immunity. It uses the base Triaxis® front end and is optimized for cost-sensitive applications where external magnetic interference is minimal or controlled by shielding.
Can the MLX90372GGO-ACE-300-SP be used in battery-powered systems?
Yes, the MLX90372GGO-ACE-300-SP supports battery-powered operation up to 18 V via its PTC overvoltage detection circuitry (VPROV1 = 21.5–24.5 V). It automatically selects battery mode when WARM_ACT_HIGH is configured, enabling robust performance in 12 V automotive systems with load-dump transients, while maintaining 8.0–10.5 mA supply current in legacy (-300) mode.
