Product details
Overview
MLX90377GGO-ADB-510-TU from Melexis is a Triaxis® monolithic magnetic position sensor IC for absolute rotary position sensing in high-field stray-field immune mode. It delivers 12-bit analog and PWM outputs with high-speed timing (≤100 µs latency), operates from -40°C to +160°C, and supports ASIL-C functional safety for PWM/SENT output modes. It is used in automotive throttle and steering wheel position sensing where robustness against external magnetic interference is critical.
For engineers reviewing the MLX90377GGO-ADB-510-TU datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (TSSOP-16), confirmed pin functions, real-world accuracy specs (±0.5° typical angular error), functional safety compliance (ISO 26262 ASIL-C), and validated alternative parts for design continuity.
Technical Context
The MLX90377GGO-ADB-510-TU implements Triaxis® Hall sensing of Bx, By, and Bz magnetic field components to compute absolute angular position without mechanical contact. Its on-chip DSP performs real-time piecewise-linear interpolation (up to 32 segments) and stray-field compensation optimized for rotary high-field configurations.
This variant uses the TSSOP-16 dual-die package with isolated ground/supply domains (VSS1/VDD1 and VSS2/VDD2), enabling redundant operation and >4 MΩ inter-die isolation. It is factory-programmed for Rotary Stray-Field Immune Mode (high-field variant), Analog/PWM output, and High Speed Mode - parameters fixed at manufacture and not reprogrammable in-system.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Resolution | 12-bit (4096 steps over 0–360°), enabling ±0.09° theoretical quantization step size |
| Angular Accuracy | ±0.5° typical total error (including INL, thermal drift, and assembly tolerance) in rotary high-field mode |
| Latency | ≤100 µs average response time from magnet movement to valid output - critical for closed-loop engine control |
| Supply Range | 4.5–5.5 V (regulated) or 6–18 V (battery), supporting direct vehicle battery connection with reverse polarity protection |
| Operating Temp | -40°C to +160°C ambient - qualified for under-hood automotive placement without heatsinking |

| Magnetic Immunity | Stray-field immune architecture rejects >15 mT external orthogonal fields - validated per ISO 11452-8 |
Pinout & Package
TSSOP-16 dual-die package with 0.65 mm pitch, 5.0 × 4.4 mm body, and exposed thermal pad (pin 0). Designed for redundancy: two independent sensor dies share no electrical connections except common VDD/VSS supply rails.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VDEC1 / VDEC2 | Dedicated decoupling pins per die - require separate 100 nF ceramic capacitors to VSS1/VSS2 for EMC stability |
| 2, 10 | VSS1 / VSS2 | Isolated ground returns per die - must be routed separately to avoid coupling faults in safety-critical systems |
| 3, 11 | VDD1 / VDD2 | Independent supply inputs per die - enable power domain separation for fault containment |
| 6, 15 | OUT2 / OUT1 | Independent PWM/analog outputs - support cross-checking or voting logic in ASIL-C architectures |
| 4, 12 | Input1 / Input2 | Test/external measurement inputs - unused in production; recommended tied to VSS for EMC |
| 5, 13 | Test2 / Test1 | Factory test access - not user-accessible; tie to VSS for noise immunity |
| 7, 8, 14, 16 | N.C. | No internal connection - must be connected to VSS per Melexis EMC guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Simultaneous Bx/By/Bz measurement enables true 360° absolute angle decoding without gear trains or multi-turn mechanisms |
| Rotary Stray-Field Immunity | Hardware-level rejection of external magnetic interference up to ±15 mT - eliminates need for magnetic shielding in chassis-mounted sensors |
| Programmable Transfer Curve | Up to 32-point piecewise-linear calibration stored in NVRAM - compensates for magnet nonlinearity and mechanical tolerances |
| Dual-Die Redundancy | Two independent sensor paths in one TSSOP-16 package - supports lockstep comparison or fail-safe fallback per ISO 26262 requirements |
| Fast PWM Output | Configurable 100–200 kHz carrier with 12-bit resolution and ≤100 µs latency - meets real-time torque control loop timing in electric power steering |

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 |
|---|---|---|---|
| MLX90377GGO-ADB-530-TU | Same TSSOP-16 package and rotary stray-field immune mode, but configured for SENT output (3 µs tick) instead of analog/PWM | Used where host ECU requires SENT protocol decoding (e.g., newer powertrain ECUs), not analog/PWM interfaces | Select when system architecture mandates SENT communication; not interchangeable without hardware redesign. |
| MLX90371GGO-ADB-510-TU | Legacy Triaxis® generation with identical pinout and rotary high-field mode, but 10-bit resolution and no ASIL-C certification | Suitable for cost-sensitive industrial applications where functional safety is not required | Choose for non-automotive designs needing footprint compatibility but lower performance and safety overhead. |
Compared with MLX90377GGO-ADB-510-TU, the ADB-530 variant shifts interface priority to SENT for diagnostic-rich environments, while the MLX90371 offers legacy compatibility at reduced resolution and safety scope - both require explicit validation against the target ECU interface and safety architecture.

FAQ
What output protocols does the MLX90377GGO-ADB-510-TU support?
The MLX90377GGO-ADB-510-TU is factory-configured for analog ratiometric and PWM output modes only. It does not support SENT or SPC protocols - those require different option codes (e.g., ADB-530 for SENT). The output mode is fixed during manufacturing and cannot be changed via programming or external configuration.
Is the MLX90377GGO-ADB-510-TU pin-compatible with other MLX90377 variants in TSSOP-16?
Yes, all MLX90377 variants in the GO (TSSOP-16) package share identical pinout and mechanical footprint, including MLX90377GGO-ADB-510-TU. However, electrical behavior differs by option code - for example, ADB-530 outputs SENT frames, while ADB-510 outputs analog/PWM. Interchangeability requires matching output protocol and safety requirements.
Does the MLX90377GGO-ADB-510-TU require external decoupling capacitors?
Yes, the MLX90377GGO-ADB-510-TU requires two 100 nF ceramic capacitors: one between VDEC1 and VSS1, and another between VDEC2 and VSS2. These are mandatory for stable operation and EMC compliance, as specified in Section 3.2 of the datasheet. Omitting them causes output instability and increased susceptibility to supply noise.
How is functional safety implemented in the MLX90377GGO-ADB-510-TU?
The MLX90377GGO-ADB-510-TU achieves ISO 26262 ASIL-C capability for PWM and SENT outputs through dual-die redundancy, built-in diagnostics (watchdog, memory ECC, signal path monitoring), and fault handling within <10 ms. It is certified as a Safety Element out of Context (SEooC), meaning its safety mechanisms are validated independently of system integration.
Can the MLX90377GGO-ADB-510-TU be used in linear position sensing applications?
No - the MLX90377GGO-ADB-510-TU is specifically configured for Rotary Stray-Field Immune Mode (high-field variant), optimized for angular position decoding. For linear sensing, Melexis specifies variants with ADB-2xx option codes (e.g., ADB-210). Using ADB-510 in linear configurations yields uncalibrated, non-monotonic output due to mismatched magnetic front-end tuning.
