Product details
Overview
MLX90377GVS-ADB-333-RE from Melexis is a monolithic Triaxis® Hall-based magnetic position sensor IC for absolute rotary or linear position sensing. It delivers 12-bit SENT output with 3 μs tick time, operates from -40 °C to 160 °C, and uses DMP-4 package with dual ground pins. It is ASIL-C capable in SENT mode and supports stray-field immune operation in Standard/Legacy Mode.
For engineers reviewing the MLX90377GVS-ADB-333-RE datasheet, pinout, applications, or equivalent options, this page provides verified functional context, validated DMP-4 pin mapping, confirmed SENT timing (3 μs tick), ASIL-C safety capability, and real-world automotive use cases including throttle and pedal position sensing.
Technical Context
The MLX90377GVS-ADB-333-RE integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz components, a 12-bit ADC, DSP-based signal processing engine, and SENT output stage compliant with SAE J2716 APR2016. Its architecture enables absolute angle decoding (0–360°) or linear displacement measurement using external magnet configurations.
This variant implements Standard/Legacy Mode with SENT protocol, 3 μs tick time, and DMP-4 packaging - a PCB-less dual-mold solution with built-in decoupling capacitance. It features programmable transfer characteristics (up to 32-point PWL), on-chip diagnostics, and robustness against stray magnetic fields per its -3xx option code.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic 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 1 μs tick time instead of 3 μs; no trim/form STD2 configuration. | Compatible with legacy SENT receivers requiring faster tick rates; lacks the standardized lead form (STD2) for automated insertion. | Select when interfacing with older ECU hardware or when board-level space constraints allow non-trimmed leads. |
| MLX90371GVS-ADB-030-RE | Legacy Triaxis® generation; 10-bit resolution, fixed 3-point linearization, no ASIL-C certification, and only analog/PWM outputs. | Suitable for cost-sensitive non-safety-critical applications like HVAC damper control or basic seat position feedback. | Choose only for brownfield designs where SENT interface or ASIL-C is not required and resolution >10 bits is unnecessary. |
Compared with MLX90377GVS-ADB-330-RE, the -333-RE offers guaranteed STD2 lead form and optimized 3 μs tick timing for newer ECUs; versus MLX90371GVS-ADB-030-RE, it adds ASIL-C support, 12-bit resolution, and programmable PWL - making it suitable for next-generation powertrain and chassis control systems.

FAQ
What output protocol does the MLX90377GVS-ADB-333-RE support?
The MLX90377GVS-ADB-333-RE supports SENT output only, specifically compliant with SAE J2716 APR2016 and configured for 3 μs tick time. It does not support analog, PWM, or SPC modes - this is fixed by factory programming per the ADB-333 option code and cannot be reconfigured in the field.
Is the MLX90377GVS-ADB-333-RE pin-compatible with earlier Triaxis® sensors?
Yes, the MLX90377GVS-ADB-333-RE uses the DMP-4 package with pin-to-pin compatibility to prior-generation Triaxis® devices such as MLX90363 and MLX90364. Its four-terminal layout (VSS-VDD-OUT-VSS) maintains identical footprint and soldering requirements, enabling drop-in replacement in existing DMP-4 designs.
Does the MLX90377GVS-ADB-333-RE require external decoupling capacitors?
No, the MLX90377GVS-ADB-333-RE integrates decoupling capacitance within the DMP-4 package. The VDEC function is embedded, eliminating the need for external ceramic capacitors - simplifying PCB layout and improving reliability in high-vibration environments like engine compartments.
What functional safety level is certified for the MLX90377GVS-ADB-333-RE?
The MLX90377GVS-ADB-333-RE is ISO 26262 ASIL-C capable in SENT output mode as a Safety Element out of Context (SEooC). This certification covers internal diagnostics, memory ECC, watchdog timers, and fault handling - enabling integration into ASIL-D systems when combined with appropriate system-level mechanisms.
Can the MLX90377GVS-ADB-333-RE measure both rotary and linear position?
Yes, the MLX90377GVS-ADB-333-RE supports both rotary and linear position measurement using the same Triaxis® 3D Hall architecture. With appropriate magnet placement (e.g., diametrically magnetized ring for rotation or side-facing magnet for linear stroke), it decodes absolute position from Bx, By, and Bz components without hardware change.
