Product details
Overview
MLX90376GDC-ABA-680-SP from Melexis is a Triaxis® monolithic magnetic position sensor IC for absolute rotary position sensing up to 360° in stray-field immune mode. It features SPC (Short PWM Code) output, AEC-Q100 Grade-0 qualification (-40°C to +160°C), and SOIC-8 single-die packaging. Used in automotive throttle and steering wheel position sensing where robustness against 5 mT stray fields is required.
For engineers reviewing the MLX90376GDC-ABA-680-SP datasheet, pinout, applications, or equivalent options, key selection criteria include SPC protocol timing (1.5 μs tick), 360° stray-field immune angular range, ASIL-C functional safety compliance, and SOIC-8 thermal performance under high-temperature engine bay conditions.
Technical Context
The MLX90376GDC-ABA-680-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, enabling contactless 360° angle decoding without mechanical wear. Its on-chip DSP performs real-time piecewise-linearization (up to 32-point) and programmable transfer characteristics.
It operates exclusively in Rotary Stray-Field Immune Mode (360° variant, -6xx option code) with fixed SPC output protocol-non-reprogrammable per ordering code-and supports ASIL-C diagnostics via built-in watchdogs, CRC, and fault-handling time intervals compliant with ISO 26262 SEooC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Protocol | SPC (Short PWM Code) with 1.5 μs tick time; enables fast, noise-immune digital communication compatible with standard automotive microcontrollers. |
| Angular Range | 0–360° absolute rotary position; validated for stray-field immunity up to 5 mT (4 kA/m) per ISO 11452-8. |
| Operating Temp | -40°C to +160°C; qualified per AEC-Q100 Grade-0, suitable for under-hood automotive placement. |
| Supply Current | 8–11.5 mA typical (SMD package); low-power operation optimized for continuous engine control unit monitoring. |
| Functional Safety | ISO 26262 SEooC, ASIL-C for SPC output; includes diagnostic test intervals, fault handling time ≤ 10 ms, and dual-watchdog architecture. |
| Package | SOIC-8 (DC code); single-die, RoHS-compliant surface-mount package with exposed pad thermal path. |
| Startup Time | ≤ 4.2 ms (low-power analog reference baseline); SPC startup defined by trigger pulse reception after internal initialization. |
Pinout & Package
MLX90376GDC-ABA-680-SP uses the SOIC-8 (DC) package: 8-pin, 3.9 mm × 4.9 mm body, 1.27 mm pitch, with exposed thermal pad (EP) recommended for soldering per Melexis Section 17.1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | SPC push-pull output; delivers encoded angle data with status nibble; requires 3–55 kΩ pull-up for emission compliance. |
| 2 | TEST | Factory test pin; not user-accessible in final application; recommended tied to GND for EMC. |
| 3 | VSS | Ground reference for analog/digital circuitry; shared return path; must be low-impedance for noise immunity. |
| 4 | VDD | Primary supply input (4.5–18 V); supports battery and regulated rail; includes reverse voltage protection to -14 V. |
| 5 | INPUT | Factory test pin; no user function; recommended tied to GND for EMC stability. |
| 6 | NC | No connect; internally unconnected; must be tied to VSS per datasheet for optimal EMC behavior. |
| 7 | NC | No connect; internally unconnected; must be tied to VSS per datasheet for optimal EMC behavior. |
| 8 | VDEC | Decoupling pin for internal LDO; requires 100 nF ceramic capacitor to VSS close to the pin for stable regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous measurement of Bx, By, Bz enables true 3D magnetic field resolution-critical for accurate 360° angle decoding in misaligned or noisy magnetic environments. |
| Stray-Field Immunity | Validated immunity to 5 mT external fields (ISO 11452-8); eliminates need for magnetic shielding in compact throttle or suspension modules. |
| SPC Output Protocol | 1.5 μs tick time enables sub-100 μs full-frame transmission; supports status & communication nibble (SCN) for real-time diagnostics without host processor overhead. |
| Programmable Transfer Curve | Up to 32-point piecewise-linear (PWL) calibration allows precise linearization of non-ideal magnet trajectories-reducing ECU compensation effort. |
| AEC-Q100 Grade-0 | Qualified across -40°C to +160°C ambient; ensures reliability in direct engine-mount applications without derating or forced cooling. |

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; identical SPC output, 360° stray-field mode, but adds inter-die isolation (4 MΩ) and redundancy. | Required for ASIL-D systems needing hardware redundancy; larger footprint and higher cost than SOIC-8. | Select when dual-die fault containment is mandated-e.g., steer-by-wire actuator feedback. |
| MLX90377GDC-ABA-680-SP | Newer generation with enhanced SPC timing margin (1.2 μs min tick), lower quiescent current (6.5 mA), and extended diagnostic coverage. | Backward-compatible pinout and protocol; supports same 360° stray-field use cases with improved power efficiency. | Prefer for new designs targeting longer EOL; verify SPC decoder timing compatibility with legacy ECUs. |
Compared with MLX90376GDC-ABA-680-SP, the TSSOP-16 dual-die alternative provides hardware-level fault isolation for higher ASIL targets, while the MLX90377 offers tighter timing margins and lower power-both retain identical SPC framing and 360° stray-field immunity but differ in package scalability and lifecycle roadmap.

FAQ
What output protocol does the MLX90376GDC-ABA-680-SP support, and is it configurable?
The MLX90376GDC-ABA-680-SP supports only SPC (Short PWM Code) output with a fixed 1.5 μs tick time, as defined by its ABA-680 option code. This output mode is factory-programmed and cannot be reconfigured by the end user-unlike other MLX90376 variants offering SENT, PWM, or analog outputs. The SPC frame includes status and communication nibbles for integrated diagnostics.
Does the MLX90376GDC-ABA-680-SP meet automotive functional safety requirements?
Yes, the MLX90376GDC-ABA-680-SP is certified per ISO 26262 SEooC with ASIL-C capability for its SPC output path. It includes built-in safety mechanisms such as dual watchdogs (AWD/IWD), CRC-protected SPC frames, diagnostic test intervals (DTI), and fault-handling time intervals ≤ 10 ms-all documented in the MLX90376 safety manual (Rev 003). ASIL-B applies only to analog variants, not this SPC-specific part.
What is the operating temperature range and qualification status of the MLX90376GDC-ABA-680-SP?
The MLX90376GDC-ABA-680-SP is qualified per AEC-Q100 Grade-0, supporting continuous operation from -40°C to +160°C ambient. This rating is verified across all electrical, magnetic, and timing specifications in the datasheet (Rev 003), making it suitable for under-hood placement in engine control, transmission, and brake modules without thermal derating.
How is stray-field immunity implemented in the MLX90376GDC-ABA-680-SP, and what is the validated limit?
The MLX90376GDC-ABA-680-SP achieves stray-field immunity through Triaxis® Hall technology combined with on-chip differential signal processing and proprietary magnetic concentrator (IMC®) geometry. It is validated per ISO 11452-8 to maintain full 360° angular accuracy in external DC stray fields up to 5 mT (4 kA/m)-a requirement confirmed in Section 8.5 of the datasheet for -6xx SMD variants.
What package type and pin configuration does the MLX90376GDC-ABA-680-SP use, and are there layout recommendations?
The MLX90376GDC-ABA-680-SP uses the SOIC-8 (DC) package with an exposed thermal pad. Pin 1 is OUT (SPC), Pins 2 and 5 are TEST/INPUT (tie to GND), Pins 6–7 are NC (tie to GND), Pin 3 is VSS, Pin 4 is VDD, and Pin 8 is VDEC (requires 100 nF decoupling to VSS). Melexis recommends grounding all unused pins and using controlled-impedance routing for the SPC output trace to minimize EMI coupling.
