Product details
Overview
MLX90377GVE-ADB-510-RX from Melexis is a monolithic Triaxis® Hall-based absolute rotary position sensor IC operating from -40°C to 160°C, delivering 12-bit analog/PWM output with high-speed mode timing (≤100 µs latency), stray-field immunity for rotary applications, and ASIL-C functional safety capability for PWM/SENT modes. It enables non-contact throttle or steering wheel position sensing in automotive powertrain and chassis systems.
For engineers reviewing the MLX90377GVE-ADB-510-RX datasheet, pinout, applications, or equivalent options, key selection criteria include its SMP-3 package footprint, rotary stray-field immune magnetic configuration (high-field variant), high-speed analog/PWM timing, and ASIL-C compliance for safety-critical vehicle control loops.
Technical Context
The MLX90377GVE-ADB-510-RX integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, enabling absolute angular position decoding up to 360° without mechanical contact. Its on-chip DSP supports programmable piecewise-linear transfer characteristics (up to 32 segments) and configurable filtering for dynamic response optimization.
It operates in Rotary Stray-Field Immune Mode (high-field variant) with analog/PWM output enabled in high-speed mode, achieving ≤100 µs latency and 12-bit resolution. The device uses internal voltage regulation, reverse-polarity protection, and built-in decoupling for robust operation in noisy automotive environments.

Pinout & Package
SMP-3 is a 3-pin surface-mount package with integrated capacitors, designed for direct soldering onto flex or rigid PCBs without discrete decoupling components. Pin 1 = VDD (supply), Pin 2 = OUT (analog/PWM output), Pin 3 = VSS (ground). Test and INPUT pins are internal-only and not externally accessible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VDD) | Supply input | Accepts 4.5–5.5 V regulated supply; includes reverse-polarity and overvoltage protection (−14 V to +37 V transient tolerance). |
| 2 (OUT) | Analog/PWM output driver | Push-pull capable; delivers ratiometric 0.5–99% VDD analog or 12-bit PWM with programmable duty cycle; supports 5–10 kΩ load. |
| 3 (VSS) | Ground reference | Low-impedance return path; used for broken-wire detection diagnostics (BVSSPU/BVSSPD thresholds defined). |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Simultaneous measurement of Bx, By, Bz enables true absolute angular position decoding without calibration per unit. |
| Rotary Stray-Field Immunity (High Field) | Robust operation in magnetically noisy environments (e.g., near motors or solenoids) using field-shaping concentrators and differential processing. |
| Programmable Transfer Characteristic | Up to 32-point piecewise-linear mapping allows precise linearization of non-ideal magnet trajectories in custom mechanical linkages. |
| ASIL-C Functional Safety Support | Dual-core diagnostic architecture, watchdog timers, memory ECC, and fault reporting via SENT/SPC enable safety-critical deployment without external monitors. |
| Integrated Decoupling (SMP-3) | Built-in ceramic capacitors eliminate need for external VDD/VSS bypass components, reducing BOM count and layout area by ~30%. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute rotary position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GVE-ADB-310-RX | Standard/Legacy Mode instead of Rotary Stray-Field Immune; same SMP-3 package and high-speed analog/PWM output. | Lacks stray-field rejection; suitable only in magnetically quiet environments like instrument clusters. | Select when cost sensitivity outweighs EMI robustness requirements and magnetic interference is absent. |
| MLX90371GSE-ADB-010-SP | Legacy Triaxis® generation; 10-bit resolution, no ASIL-C support, SOIC-8 package, fixed linear transfer function. | Lower accuracy and safety grade; requires external decoupling and lacks programmability. | Choose only for legacy redesigns where firmware and layout changes are prohibited and ASIL-B suffices. |
Compared with MLX90377GVE-ADB-510-RX, the ADB-310-RX sacrifices stray-field immunity for lower unit cost in benign environments, while the MLX90371 offers proven reliability at reduced resolution and safety scope-neither provides the high-field rotary immunity or ASIL-C capability required for next-gen powertrain control.

FAQ
What output protocols does the MLX90377GVE-ADB-510-RX support?
The MLX90377GVE-ADB-510-RX supports analog ratiometric and PWM output modes only, configured in high-speed mode per its ADB-510 option code. SENT and SPC protocols are not enabled for this variant; they require different option codes (e.g., ADB-530 for SENT). Output mode is factory-programmed and not user-reconfigurable in the field.
Is the MLX90377GVE-ADB-510-RX pin-compatible with other MLX90377 package variants?
No-MLX90377GVE-ADB-510-RX uses the 3-pin SMP-3 package (VDD, OUT, VSS), while SOIC-8 has 8 pins and TSSOP-16 has 16 pins with dual-die routing. DMP-4 shares the same 3-pin count but differs in lead form and thermal performance. Direct PCB replacement is not possible without layout revision.
How does the Rotary Stray-Field Immune Mode (High Field) affect magnet selection for MLX90377GVE-ADB-510-RX?
The Rotary Stray-Field Immune Mode (High Field) in MLX90377GVE-ADB-510-RX requires magnets with surface fields ≥400 mT to ensure reliable operation under EMI stress. It leverages integrated magnetic concentrators and differential signal processing to reject orthogonal interference, enabling use with smaller, higher-coercivity NdFeB magnets in dense engine bay layouts.
Does MLX90377GVE-ADB-510-RX include built-in diagnostics for open-circuit or short-circuit faults?
Yes-MLX90377GVE-ADB-510-RX implements passive broken-wire detection on VSS and VDD lines, with defined voltage thresholds (e.g., BVSSPU = 99.5% VDD, BVDDPD = 0.5% VDD), and active diagnostic reporting via output state modulation. These features are validated under ISO 26262 ASIL-C requirements for safety element out of context.
What is the startup time specification for MLX90377GVE-ADB-510-RX in analog high-speed mode?
In analog high-speed mode, MLX90377GVE-ADB-510-RX achieves first valid output within ≤10 ms after VDD crosses 4.1 V (VDDstartH), with full stabilization and latency compliance met within 100 µs thereafter. Startup behavior is independent of magnetic field presence and includes internal POR and clock stabilization sequences.
