Product details
Overview
MLX90377GVS-ADB-338-RE from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC in DMP-4 package, delivering 12-bit SENT output with 3 μs tick time, operating from -40°C to 160°C, and certified ASIL-C capable for SENT mode in automotive safety-critical throttle and pedal position sensing.
For engineers reviewing the MLX90377GVS-ADB-338-RE datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping, SENT protocol timing compliance, stray-field immune operation mode, functional safety classification, and validated alternative options for automotive position sensing designs.
Technical Context
The MLX90377GVS-ADB-338-RE implements Triaxis® technology to measure Bx, By, and Bz magnetic field components simultaneously, enabling absolute rotary or linear position decoding without mechanical contact. Its on-chip DSP supports programmable piecewise-linear transfer characteristics (up to 32 segments) and configurable filtering for robustness against magnetic interference.
This variant operates in Standard/Legacy Mode with SENT output (3 μs tick), uses DMP-4 packaging (PCB-less dual mold), and features reverse polarity and overvoltage protection. It is ASIL-C capable per ISO 26262 for SENT mode as a Safety Element out of Context, with built-in diagnostics including broken-wire detection on VDD and VSS.
Key Specifications

Pinout & Package
DMP-4 package: PCB-less dual-mold construction with 4 terminals, designed for direct soldering onto flex or rigid substrates. Pin-to-pin compatible with prior Triaxis® generations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog/digital domains; must be low-impedance connection to minimize noise coupling into Triaxis® front end. |
| 2 | VDD | Main supply input (4.5–18 V); includes reverse polarity and overvoltage protection circuitry up to -18 V and +37 V transient. |
| 3 | OUT | SENT open-drain output; requires external pull-up (10–55 kΩ) to VEXT ≤ 18 V; supports diagnostic signaling via status nibbles. |
| 4 | VSS | Second ground terminal - used for current return path separation and improved EMC performance in high-noise environments. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Simultaneous Bx/By/Bz measurement enables true absolute position decoding from a single moving magnet - eliminates need for multi-sensor assemblies or complex magnet geometries. |
| Programmable Transfer Curve | Up to 32-point piecewise-linear calibration allows precise linearization across non-uniform magnetic fields - reduces system-level compensation effort in production. |
| SENT v4.0 Compliance | Full SAE J2716 APR2016 implementation with CRC, status nibble, and user-defined data fields - ensures interoperability with Tier 1 ECU receivers and diagnostic tools. |
| Stray-Field Immune Operation | Configured in Standard/Legacy Mode (-338 code) - optimized for robustness against external magnetic interference in engine bay or chassis-mounted applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GVS-ADB-330-RE | Identical DMP-4 package and SENT output, but uses standard 3 μs tick without enhanced emission mode - lower EMI margin in noisy harnesses. | Same functional scope; suitable where full SAE J2716 APR2016 emission compliance is not mandated by OEM. | Select when cost optimization is prioritized and system-level EMC testing confirms adequate noise immunity. |
| MLX90371GVS-ADB-338-RE | Legacy Triaxis® generation with identical pinout and SENT interface, but limited to 10-bit resolution and no ASIL-C certification. | Applicable only in non-safety-critical positions (e.g., HVAC flaps); lacks diagnostic coverage for ASIL-B/C systems. | Choose only for legacy redesigns where qualification timelines prohibit new-generation validation. |
Compared with MLX90377GVS-ADB-338-RE, the ADB-330 variant offers identical functionality at lower EMI robustness, while the MLX90371 alternative sacrifices resolution and safety certification for backward compatibility - making the ADB-338 the optimal choice for new ASIL-C throttle or pedal designs requiring full APR2016 SENT compliance.
