Product details
Overview
MLX90376GDC-ABA-680-RE from Melexis is a Triaxis® monolithic magnetic position sensor IC for absolute rotary position sensing up to 360° in stray-field immune mode, featuring SPC (Short PWM Code) output, AEC-Q100 Grade-0 qualification (-40°C to +160°C), and SOIC-8 single-die packaging. It delivers robust angle measurement in automotive throttle and steering wheel position systems using integrated Hall front-end and DSP signal processing.
For engineers reviewing the MLX90376GDC-ABA-680-RE datasheet, pinout, applications, or equivalent options, this page provides verified technical context, real-world timing specs, functional safety alignment (ASIL C), package-specific pin definitions, and validated alternative options for SPC-output magnetic position sensing.
Technical Context
The MLX90376GDC-ABA-680-RE implements Triaxis® Hall technology to measure all three magnetic flux components (Bx, By, Bz), enabling true 360° absolute angle decoding without mechanical contact. Its on-chip DSP supports programmable piecewise-linear transfer characteristics and configurable diagnostics.
This variant operates exclusively in Rotary Stray-Field Immune Mode (360°), uses SPC output with 1.5 μs tick time, and is implemented in SOIC-8 (DC) single-die packaging. It achieves ASIL C compliance per ISO 26262 SEooC for SPC output and supports stray-field immunity up to 5 mT (4 kA/m) as defined in ISO 11452-8.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Protocol | SPC (Short PWM Code) with 1.5 μs tick time - enables fast, secure serial communication with built-in status & communication nibble (SCN) for error reporting. |
| Operating Temperature | -40°C to +160°C - qualified per AEC-Q100 Grade-0 for under-hood automotive applications including throttle and steering modules. |
| Stray-Field Immunity | Up to 5 mT (4 kA/m) - certified per ISO 11452-8, allowing reliable operation in high-interference environments like engine compartments. |
| Angle Range | 0–360° absolute rotary position - enabled by Triaxis® 3D magnetic sensing and on-chip DSP, eliminating need for external magnets or complex calibration. |
| Supply Current | 8–11 mA typical (SMD packages, -68x code) - optimized for low-power SPC mode while maintaining full diagnostic coverage and ASIL C compliance. |
| Functional Safety | ISO 26262 SEooC, ASIL C for SPC output - includes programmable diagnostics, fault handling time interval (FHTI), and end-user configurable safety mechanisms. |
| Package | SOIC-8 (DC) - surface-mount, RoHS-compliant single-die package with exposed pad not present; pin-compatible with standard SOIC-8 footprints. |
Pinout & Package
MLX90376GDC-ABA-680-RE is housed in an SOIC-8 (DC) package - a standard 8-pin surface-mount device with gull-wing leads, no exposed pad, and RoHS-compliant molding compound. Pin assignments are validated per Melexis datasheet Rev. 003 Section 3.2.1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | SPC output signal - push-pull driver delivering Short PWM Code frames; requires external pull-up resistor (3–55 kΩ) matched to capacitive load for valid trigger pulse timing. |
| 2 | TEST | Factory test pin - not intended for end-user connection; recommended to tie to ground for optimal EMC performance. |
| 3 | VSS | Ground reference - common return path for internal circuitry and output stage; must be low-impedance to ensure stable SPC timing and diagnostic accuracy. |
| 4 | VDD | Supply input - accepts 4.5–5.5 V regulated supply or 5–18 V battery input; includes under-voltage lockout (UVLO) at 3.75–4.05 V and PTC programming entry thresholds. |
| 5 | INPUT | Factory test pin - unused in application; recommended to tie to ground to minimize noise coupling and improve EMC robustness. |
| 6 | NC | No connect - internally unconnected; must be tied to ground per datasheet recommendation to reduce EMI susceptibility. |
| 7 | NC | No connect - internally unconnected; grounding prevents floating node effects and ensures consistent startup behavior. |
| 8 | VDEC | Decoupling pin - requires local 100 nF ceramic capacitor to VSS for stable internal voltage regulation and noise suppression on analog/DSP blocks. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Measures Bx, By, Bz simultaneously to resolve absolute 360° angle without mechanical stops or multi-magnet assemblies - reduces system BOM and improves long-term reliability. |
| SPC Output with SCN | Delivers status & communication nibble (SCN) in every frame for real-time fault detection (e.g., open-circuit, short-to-battery, broken-wire), supporting ASIL C diagnostic coverage. |
| Programmable Transfer Characteristic | Supports 4-, 8-, 16-, or 32-point piecewise-linear (PWL) calibration - enables precise linearization across non-ideal magnet trajectories without host MCU intervention. |
| Stray-Field Immune 360° Mode | Validates angle accuracy under 5 mT external DC/AC magnetic interference - critical for placement near motors, solenoids, or high-current traces in vehicle chassis. |
| End-User Programmable Diagnostics | Allows configuration of diagnostic test intervals (DTI), fault reaction times, and fail-safe states via NVRAM - simplifies integration into diverse ASIL C architectures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90376GGO-ADA-680-RE | TSSOP-16_EP dual-die package with isolation between dies (4 MΩ min); identical SPC output, 360° stray-field immune mode, and ASIL C compliance. | Required where hardware redundancy or die-level isolation is mandated for ASIL D decomposition; occupies larger PCB area and requires EP soldering. | Select when system-level fault tolerance demands physical separation of sensing channels beyond single-die capability. |
| MLX90376GVD-ADA-680-RE | SMP-4 PCB-less single-mold package; same SPC protocol and 360° mode but with 4-pin footprint (VDD/VSS/OUT1/OUT2) and no NC pins. | Targeted at ultra-compact, cost-sensitive modules where board space is constrained and dual-output (redundant or differential) is needed. | Choose for space-constrained automotive modules requiring minimal assembly steps and no PCB routing for sensor die. |
Compared with MLX90376GDC-ABA-680-RE, the GO variant adds die-level isolation for higher ASIL decomposition, while the VD variant eliminates PCB dependency entirely - both retain identical SPC timing, stray-field immunity, and functional safety architecture but differ in mechanical integration and redundancy topology.

FAQ
What output protocol does the MLX90376GDC-ABA-680-RE support?
The MLX90376GDC-ABA-680-RE supports only SPC (Short PWM Code) output with a fixed 1.5 μs tick time, as defined by its ABA-680 option code. It cannot be reprogrammed to SENT, PWM, or analog modes - output protocol is factory-configured and immutable in end-use. This ensures deterministic timing and ASIL C diagnostic coverage for safety-critical deployments.
Is the MLX90376GDC-ABA-680-RE qualified for automotive under-hood use?
Yes, the MLX90376GDC-ABA-680-RE is AEC-Q100 Grade-0 qualified for operation from -40°C to +160°C and meets ISO 11452-8 for stray magnetic field immunity up to 5 mT. Its SOIC-8 package and internal diagnostics support direct mounting in engine compartments, transmission housings, and brake modules without additional shielding.
Does the MLX90376GDC-ABA-680-RE provide functional safety certification?
Yes, the MLX90376GDC-ABA-680-RE is developed as a Safety Element out of Context (SEooC) per ISO 26262 and achieves ASIL C for SPC output. It includes programmable diagnostics, fault handling time interval (FHTI) control, and status & communication nibble (SCN) reporting - all documented in Melexis' functional safety manual for integration into ASIL C systems.
What is the pin configuration and recommended layout for MLX90376GDC-ABA-680-RE?
The MLX90376GDC-ABA-680-RE uses an SOIC-8 (DC) package with pins: 1=OUT (SPC), 2=TEST (ground), 3=VSS, 4=VDD, 5=INPUT (ground), 6=NC (ground), 7=NC (ground), 8=VDEC (100 nF decoupling to VSS). Grounding all NC and TEST pins minimizes EMI and ensures stable startup per Melexis layout guidelines.
Can the MLX90376GDC-ABA-680-RE measure linear position?
No - the MLX90376GDC-ABA-680-RE is configured exclusively for 360° rotary position sensing in Stray-Field Immune Mode. While the base MLX90376 family supports linear motion in Legacy Mode (-3xx codes), the -680 option code locks the device to rotary 360° operation with SPC output and cannot be repurposed for linear displacement.
