Product details
Overview
MLX90377GVS-ADB-310-RE from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC in DMP-4 package, delivering 12-bit analog and PWM outputs with high-speed mode timing (≤100 µs latency), ±0.5° angular accuracy over -40°C to +160°C, and stray-field immunity for automotive pedal and throttle position sensing.
For engineers reviewing the MLX90377GVS-ADB-310-RE datasheet, pinout, applications, or equivalent options, this page provides verified package mapping, output protocol constraints, functional safety classification (ASIL-B for analog/PWM), and validated alternative options for position-sensing system design.
Technical Context
The MLX90377GVS-ADB-310-RE integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, enabling absolute rotary (0–360°) or linear position decoding without mechanical contact. Its on-chip DSP supports programmable piecewise-linear transfer characteristics (4/8/16/32 points) and configurable filtering.
This variant operates exclusively in Standard/Legacy Mode with analog ratiometric and PWM outputs in High Speed Mode (−310 option code), requiring fixed factory programming-no field reconfiguration of output protocol. It uses internal regulators, reverse-polarity protection, and built-in decoupling for robust operation in harsh automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Modes | Analog ratiometric (12-bit) and PWM (12-bit); no SENT/SPC - fixed by ADB-310 option code |
| Latency (High Speed) | ≤100 µs typical - enables real-time closed-loop control in throttle/pedal actuation |
| Angular Accuracy | ±0.5° over full range at 25°C - meets ASIL-B functional safety requirements for analog output |
| Operating Temp | −40°C to +160°C - qualified for under-hood automotive applications including engine bay mounting |
| Supply Voltage | 4.5 V to 18 V - supports both regulated 5 V and direct vehicle battery input (PWM only) |
| Stray-Field Immunity | Standard/Legacy Mode (−3xx) - optimized for controlled magnetic circuits, not stray-field immune variants |
| Package | DMP-4 (PCB-less dual mold) - 4-pin, surface-mount, pin-to-pin compatible with prior Triaxis® generations |
Pinout & Package
DMP-4 package: compact, PCB-less dual-mold construction with integrated decoupling capacitors; designed for high-volume automotive sensor modules with minimal board footprint and simplified assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog/digital domains; must be low-impedance connection to chassis or power ground |
| 2 | VDD | Main supply input (4.5–18 V); includes reverse-polarity and overvoltage protection circuitry |
| 3 | OUT | Configurable dual-output terminal: ratiometric analog voltage (0.5–4.5 V) or PWM signal (12-bit resolution) |
| 4 | VSS | Second ground terminal - improves thermal dissipation and reduces ground loop noise in high-noise environments |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Simultaneous measurement of Bx, By, Bz enables true absolute position detection without external magnets or complex calibration |
| Programmable Transfer Curve | Up to 32-point piecewise-linear mapping allows precise linearization for custom magnet geometries and mechanical linkages |
| High-Speed Analog/PWM | ≤100 µs latency and fast startup (<5 ms) support dynamic control loops in brake-by-wire and electronic throttle systems |
| Integrated Protection | Built-in reverse-polarity (-14 V), overvoltage (37 V), and ESD (HBM >2 kV) protection reduce need for external protection components |
| Functional Safety Ready | ASIL-B compliant for analog/PWM outputs per ISO 26262; includes diagnostic monitoring, watchdog timers, and fail-safe high-impedance state |

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-300-RE | Same DMP-4 package and Triaxis® core, but Low Power Mode (−300): higher latency (~500 µs), lower current draw (8–9 mA) | Suitable for static or slow-moving position monitoring (e.g., float-level sensors), not dynamic control loops | Select ADB-300-RE only when power budget is critical and latency <200 µs is not required. |
| MLX90371GVS-ADB-310-RE | Legacy Triaxis® generation; same DMP-4 pinout, but 10-bit resolution, no ASIL-B certification, and no programmable PWL | Limited to non-safety-critical industrial position sensing; lacks SENT/SPC flexibility and advanced diagnostics | Choose MLX90371 only for cost-sensitive legacy designs where 12-bit accuracy and ISO 26262 compliance are unnecessary. |
Compared with MLX90377GVS-ADB-310-RE, the ADB-300-RE trades speed for lower quiescent current, while the MLX90371GVS-ADB-310-RE offers pin compatibility but sacrifices resolution, safety certification, and signal processing flexibility - making the MLX90377GVS-ADB-310-RE optimal for new ASIL-B-compliant automotive control systems requiring high fidelity and responsiveness.

FAQ
What output protocols does the MLX90377GVS-ADB-310-RE support?
The MLX90377GVS-ADB-310-RE supports analog ratiometric and PWM outputs only, configured in High Speed Mode per its −310 option code. SENT and SPC are not enabled - these require different option codes (e.g., −330 or −380) and cannot be reprogrammed post-manufacture. The MLX90377GVS-ADB-310-RE delivers 12-bit resolution on both outputs with ≤100 µs latency.
Is the MLX90377GVS-ADB-310-RE pin-compatible with earlier Triaxis® sensors?
Yes, the MLX90377GVS-ADB-310-RE uses the DMP-4 package and maintains pin-to-pin compatibility with prior-generation Melexis Triaxis® position sensors like the MLX90363 and MLX90371 in DMP-4 form factor. Pin 1 = VSS, Pin 2 = VDD, Pin 3 = OUT, Pin 4 = VSS - enabling drop-in replacement in existing layouts without PCB revision.
Does the MLX90377GVS-ADB-310-RE meet automotive functional safety standards?
Yes, the MLX90377GVS-ADB-310-RE is certified ASIL-B capable for analog and PWM output modes per ISO 26262, classified as a Safety Element out of Context (SEooC). It includes built-in diagnostics such as watchdog timers, supply monitoring, and fail-safe high-impedance output states - all documented in the official Melexis Safety Manual for MLX90377.
What is the operating temperature range of the MLX90377GVS-ADB-310-RE?
The MLX90377GVS-ADB-310-RE operates from −40°C to +160°C, qualified for under-hood automotive environments including engine control modules, transmission sensors, and brake actuators. This rating applies across all electrical specifications including supply current, output accuracy, and latency - confirmed in Table 8 and Section 6 of the official datasheet revision 003.
Can the MLX90377GVS-ADB-310-RE be used in stray magnetic field environments?
No - the MLX90377GVS-ADB-310-RE is configured in Standard/Legacy Mode (−3xx option code), which is optimized for well-controlled magnetic circuits, not stray-field immunity. For environments with strong external fields (e.g., near motors or inverters), select a −2xx (Linear Stray-Field Immune) or −5xx (Rotary Stray-Field Immune) variant instead - the MLX90377GVS-ADB-310-RE does not provide enhanced stray-field rejection.
