Product details
Overview
MLX90376GGO-ABA-630-RE from Melexis is a Triaxis® monolithic magnetic position sensor IC for rotary 360° stray-field immune angle sensing, featuring SENT (SAE J2716 APR2016) output with 3 μs tick time, AEC-Q100 Grade-0 qualification (−40 °C to +160 °C), and dual-die TSSOP-16_EP package. It delivers ASIL C functional safety compliance for SENT mode and robustness against stray fields up to 5 mT.
For engineers reviewing the MLX90376GGO-ABA-630-RE datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SENT timing specs, dual-die isolation data, stray-field immunity validation, and automotive-grade functional safety implementation details.
Technical Context
The MLX90376GGO-ABA-630-RE implements Triaxis® Hall sensing of Bx, By, and Bz magnetic components to compute absolute angular position without mechanical contact. Its dual-die architecture in TSSOP-16_EP enables redundancy and isolation resistance ≥4 MΩ between dies.
This variant is factory-configured for Rotary Stray-Field Immune Mode (360°), SENT output only (3 μs tick), high-speed operation, and operates across −40 °C to +160 °C with supply voltage 4.5–5.5 V. It supports ISO 26262 SEooC with ASIL C for SENT output and includes built-in diagnostics including CRC, watchdog, and broken-wire detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Protocol | SENT (SAE J2716 APR2016) with 3 μs tick time - enables secure, error-coded serial transmission compatible with automotive ECUs. |
| Operating Temperature | −40 °C to +160 °C - qualified per AEC-Q100 Grade-0 for under-hood automotive applications. |
| Functional Safety | ISO 26262 SEooC, ASIL C for SENT output - supports safety-critical steering and throttle position systems. |
| Magnetic Immunity | Stray-field immune up to 5 mT (4 kA/m) per ISO 11452-8 - maintains accuracy in high-interference environments like electric powertrains. |
| Package | TSSOP-16_EP (GO code) - dual-die configuration with exposed pad for thermal management and die-to-die isolation ≥4 MΩ. |

| Startup Time | Tstup ≤ 13.3 ms (safe startup) - ensures rapid valid-angle delivery after power-on reset for real-time control loops. |
Pinout & Package
TSSOP-16_EP (GO) package with exposed pad (EP) for thermal dissipation and mechanical stability; dual-die layout enables redundant signal paths and functional safety separation.
| Pin/Terminal | Circuit Role | Design Meaning |

| 1, 8, 10, 16 | NC | Not connected - recommended to tie to ground for EMC performance. |
| 2, 9 | VDEC1 / VDEC2 | Decoupling pins for die 1 and die 2 - require local 100 nF ceramic capacitors to VSS for noise suppression. |
| 3, 11 | OUT1 / OUT2 | Dual SENT outputs - support independent diagnostic comparison or voting logic for ASIL C compliance. |
| 4, 12 | TEST1 / TEST2 | Factory test access - not intended for end-user use; tie to ground if unused. |
| 5, 13 | VSS1 / VSS2 | Separate ground terminals per die - enable isolation measurement and fault containment. |
| 6, 14 | VDD1 / VDD2 | Independent supply inputs per die - allow supply monitoring and independent power domain control. |
| 7, 15 | INPUT1 / INPUT2 | Test input pins - used during production testing; no functional role in operation. |

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-ABA-600-RE | Analog/PWM output (low-power mode), no SENT; same 360° stray-field immune configuration and TSSOP-16_EP package. | Suitable for legacy ECU interfaces requiring ratiometric analog or PWM, not digital serial protocols. | Select when SENT infrastructure is unavailable or system cost targets exclude protocol translation hardware. |
| MLX90376GGO-ABA-610-RE | Analog/PWM output (high-speed mode); identical package, temperature range, and magnetic performance but different output stage and timing. | Used where faster analog refresh (200 μs) is prioritized over digital diagnostics and CRC-protected communication. | Choose for non-safety-critical applications needing minimal latency without functional safety certification overhead. |
Compared with MLX90376GGO-ABA-630-RE, the -600-RE variant trades SENT's error resilience and ASIL C readiness for analog simplicity, while the -610-RE retains high-speed analog timing but lacks SENT's deterministic frame structure and integrated diagnostics - making the -630-RE uniquely suited for new ASIL C–compliant automotive designs requiring serial position reporting.

FAQ
What output protocol does the MLX90376GGO-ABA-630-RE support?
The MLX90376GGO-ABA-630-RE is factory-configured exclusively for SENT (SAE J2716 APR2016) output with a 3 μs tick time. It does not support analog, PWM, or SPC modes - the output protocol is fixed by option code ABA-630 and cannot be reprogrammed in the field. This ensures deterministic timing and ASIL C compliance for automotive safety applications.
Is the MLX90376GGO-ABA-630-RE pin-compatible with other MLX90376 variants in TSSOP-16_EP?
Yes, the MLX90376GGO-ABA-630-RE shares identical pinout and footprint with all GO-code MLX90376 variants in TSSOP-16_EP, including -600-RE and -610-RE. However, output behavior differs: -630-RE drives SENT on both OUT1 and OUT2, while -600-RE and -610-RE deliver analog/PWM signals. PCB layout is interchangeable, but firmware and ECU interface must match the selected output mode.
Does the MLX90376GGO-ABA-630-RE support functional safety certification?
Yes, the MLX90376GGO-ABA-630-RE is certified per ISO 26262 SEooC with ASIL C for its SENT output path, and AEC-Q100 Grade-0 qualified (−40 °C to +160 °C). Its dual-die TSSOP-16_EP package enables hardware-level redundancy, and built-in diagnostics - including CRC, watchdog timers, and broken-wire detection - are fully documented in the safety manual for integration into ASIL C systems.
What is the magnetic stray-field immunity specification for the MLX90376GGO-ABA-630-RE?
The MLX90376GGO-ABA-630-RE achieves stray-field immune 360° angle sensing up to 5 mT (4 kA/m) as validated per ISO 11452-8. This is enabled by Triaxis® technology and on-chip signal processing that rejects orthogonal interference - critical for placement near electric motors, inverters, or high-current busbars in modern vehicle architectures.
How is power supply decoupling implemented for the MLX90376GGO-ABA-630-RE?
The MLX90376GGO-ABA-630-RE requires two dedicated decoupling paths: VDEC1 (pin 2) and VDEC2 (pin 9), each connected to a local 100 nF ceramic capacitor routed to its respective VSS1 (pin 5) and VSS2 (pin 13). This dual-path design maintains noise isolation between dies and ensures stable operation under fast transient loads typical in SENT communication bursts.
