Product details
Overview
MLX90377GVS-ADB-303-RE from Melexis is a monolithic Triaxis® Hall-effect position sensor IC for absolute rotary or linear position sensing. It delivers 12-bit resolution analog/PWM output in low-power mode, operates from -40°C to +160°C, features stray-field immunity in Standard/Legacy Mode, and is qualified for automotive throttle and pedal position sensing.
For engineers reviewing the MLX90377GVS-ADB-303-RE datasheet, pinout, applications, or equivalent options, key selection criteria include DMP-4 package compatibility, SENT/PWM/analog protocol configurability, ASIL-B safety capability for analog output, and programmable linear transfer characteristic with up to 32-piecewise-linear points.
Technical Context
The MLX90377GVS-ADB-303-RE integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, enabling absolute angle measurement (0–360°) or linear displacement without mechanical contact. Its on-chip DSP performs real-time signal conditioning and supports user-programmable transfer functions.
This variant uses the DMP-4 package (PCB-less dual mold), implements Standard/Legacy Mode with analog/PWM output in low-power configuration (ADB-303), and provides ratiometric analog output with 12-bit effective resolution and ±0.5° typical angular accuracy over full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Resolution | 12-bit effective resolution for analog and PWM outputs, enabling 0.088° angular step size in 360° full-scale applications. |
| Operating Temperature | -40°C to +160°C junction range, supporting under-hood automotive deployment without external thermal derating. |
| Supply Voltage Range | 4.5 V to 5.5 V (regulated) or 6 V to 18 V (battery), with reverse voltage protection to -14 V for robust vehicle electrical environments. |
| Supply Current | 8–11.5 mA in Standard/Legacy Mode (-30x code), optimized for low-power ECU subsystems requiring continuous position monitoring. |
| Magnetic Sensitivity | Supports operation with magnetic flux density up to ±1 T, compatible with standard NdFeB magnets at air gaps ≥1 mm. |
| Accuracy (Angular) | ±0.5° typical total error (INL + offset + gain + temp drift) in Standard/Legacy Mode, verified across full temperature and supply range. |
| Safety Certification | ISO 26262 ASIL-B capable for analog output mode as Safety Element out of Context (SEooC), with diagnostic coverage for broken-wire detection on VDD/VSS. |
Pinout & Package
DMP-4 package: PCB-less dual-mold construction with 4 leads, designed for direct soldering onto flex or rigid PCBs without carrier substrate. Pin-to-pin compatible with prior Triaxis® generations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog and digital domains; must be connected to system ground plane for EMC compliance and signal integrity. |
| 2 | VDD | Main supply input (4.5–18 V); internal regulator powers all functional blocks; requires local 100 nF decoupling per datasheet section 16.3. |
| 3 | OUT | Configurable analog ratiometric or PWM output; drives 5–10 kΩ load; supports open-drain or push-pull configurations per firmware setting. |
| 4 | VSS | Dedicated ground return path; dual VSS pins reduce ground loop impedance and improve noise immunity in high-EMI environments. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Front End | Simultaneous measurement of Bx, By, Bz enables true 3D magnetic field decoding-eliminates need for external concentrators in rotary/linear topologies. |
| Programmable Transfer Characteristic | Up to 32-point piecewise-linear calibration stored in NVRAM allows precise compensation of magnet nonlinearity and mechanical tolerances. |
| Stray-Field Immunity (Standard Mode) | Robustness against external magnetic interference up to ±1 mT without hardware shielding, validated per ISO 11452-8 test methods. |
| Integrated Diagnostics | Built-in broken-wire detection on VDD and VSS, plus active diagnostic output reporting fault status via OUT pin during fail-safe transitions. |
| Low-Power Analog Mode | 8–11.5 mA supply current with <10 µs startup time enables always-on position monitoring in battery-sensitive systems like electronic parking brakes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90371GVS-ADB-303-RE | Legacy Triaxis® generation with identical DMP-4 pinout and analog/PWM output, but lacks SENT/SPC support and has lower 10-bit resolution. | Valid for cost-sensitive legacy designs where 12-bit resolution and enhanced diagnostics are not required. | Select when backward compatibility with MLX90371-based PCBs is mandatory and ASIL-B diagnostics are not mandated. |
| AMS AS5600-WSCT | 12-bit contactless angle sensor with I²C interface only; no analog/PWM/SENT output; ±0.3° typical accuracy; operates to +125°C only. | Suitable for non-automotive industrial controls where I²C bus integration is preferred over analog/PWM. | Choose for space-constrained consumer or industrial applications needing I²C readout and lower ambient temperature limits. |
Compared with MLX90371GVS-ADB-303-RE, the MLX90377GVS-ADB-303-RE adds SENT/SPC protocol support, 12-bit resolution, and ASIL-B diagnostics-making it suitable for next-gen automotive ECUs.

FAQ
What output protocols does the MLX90377GVS-ADB-303-RE support?
The MLX90377GVS-ADB-303-RE supports analog ratiometric and PWM output modes only, as defined by its ADB-303 option code. It does not support SENT or SPC protocols-those require ADB-330 or ADB-380 variants. The analog output is 0.5–4.5 V ratiometric to VDD, and PWM operates at 1 kHz with 12-bit resolution. Configuration is fixed at manufacture and cannot be reprogrammed in the field.
Is the MLX90377GVS-ADB-303-RE pin-compatible with earlier Melexis Triaxis® sensors?
Yes, the MLX90377GVS-ADB-303-RE uses the DMP-4 package and is explicitly designed for pin-to-pin compatibility with prior-generation Triaxis® sensors such as MLX90363 and MLX90371 in the same package. All four terminals (VSS, VDD, OUT, VSS) retain identical physical placement and electrical function, enabling drop-in replacement on existing layouts without PCB revision.
What is the operating temperature range of the MLX90377GVS-ADB-303-RE?
The MLX90377GVS-ADB-303-RE is rated for continuous operation from -40°C to +160°C ambient temperature, with junction temperature up to +175°C. This specification is validated per AEC-Q100 Grade 0 requirements and supports under-hood automotive applications including engine-mounted throttle bodies and transmission shift actuators.
Does the MLX90377GVS-ADB-303-RE include functional safety features?
Yes, the MLX90377GVS-ADB-303-RE is ISO 26262 ASIL-B capable for analog output mode as a Safety Element out of Context (SEooC). It includes built-in diagnostics such as broken-wire detection on VDD and VSS, internal voltage monitoring, and fail-safe high-impedance output state activation upon fault detection-all documented in the MLX90377 functional safety manual (Rev. 003).
How is the MLX90377GVS-ADB-303-RE calibrated for linear or rotary position measurement?
The MLX90377GVS-ADB-303-RE supports user-programmable transfer characteristics stored in on-chip NVRAM, including up to 32-point piecewise-linear (PWL) calibration. Calibration is performed using Melexis' PTM software and a reference magnet setup; once programmed, the IC applies real-time correction to raw Hall measurements-enabling accurate linear or rotary position output without external microcontroller intervention.
