Product details
Overview
MLX90377GVS-ADB-333-SP 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 built-in decoupling capacitors. It is deployed in automotive throttle and pedal position sensing where stray-field immunity and ASIL-C functional safety are required.
For engineers reviewing the MLX90377GVS-ADB-333-SP datasheet, pinout, applications, or equivalent options, key selection considerations include SENT protocol compliance (SAE J2716 APR2016), DMP-4 mechanical form factor with STD2 trim, -333 option code confirming Standard/Legacy Mode + SENT + 3 μs tick + Trim & Form STD2, and ASIL-C capability for SENT output mode.
Technical Context
The MLX90377GVS-ADB-333-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, enabling robust absolute angle or displacement decoding without mechanical contact. Its on-chip DSP performs real-time signal conditioning, including programmable piecewise-linearization (up to 32 segments) and configurable filtering.
It implements SAE J2716 APR2016-compliant SENT output with 12-bit position data, CRC error detection, and diagnostic nibbles. The device supports Secure Sensor format messaging and achieves ASIL-C compliance per ISO 26262 as a Safety Element out of Context when configured for SENT output - no external safety controller required for this mode.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GGO-ADB-330-RE | TSSOP-16 dual-die package with isolation between dies; higher pin count; requires external decoupling. | Used in redundancy-critical applications (e.g., steer-by-wire) requiring die-level fault separation. | Select when dual-die isolation and independent die diagnostics are mandatory; not drop-in compatible with DMP-4 footprint. |
| MLX90377GDC-ADB-330-RE | SOIC-8 package with standard leadform; larger footprint; no integrated capacitors. | Suitable for legacy PCB designs or prototyping where DMP-4 reflow constraints are prohibitive. | Choose for compatibility with existing SOIC-8 footprints and simplified thermal management; requires external 100 nF decoupling. |
Compared with MLX90377GGO-ADB-330-RE and MLX90377GDC-ADB-330-RE, the MLX90377GVS-ADB-333-SP offers the smallest board area and lowest component count due to its PCB-less DMP-4 package with integrated capacitors and STD2 lead form - ideal for high-volume, space-constrained automotive modules requiring SENT output and ASIL-C compliance.

FAQ
What output protocol does the MLX90377GVS-ADB-333-SP support?
The MLX90377GVS-ADB-333-SP supports SENT output only, specifically SAE J2716 APR2016-compliant frames with 3 μs tick time. This is fixed by the -333 option code and cannot be changed post-manufacture. The device does not support PWM, analog, or SPC outputs in this configuration.
Is the MLX90377GVS-ADB-333-SP pin-compatible with earlier Triaxis® sensors?
Yes - the MLX90377GVS-ADB-333-SP uses the DMP-4 package with pin-to-pin compatibility to prior-generation Triaxis® position sensors. Pin assignments (VSS-VDD-OUT-VSS) match legacy DMP-4 devices, enabling drop-in replacement in existing designs without layout changes.
Does the MLX90377GVS-ADB-333-SP require external decoupling capacitors?
No - the DMP-4 package of the MLX90377GVS-ADB-333-SP integrates ceramic decoupling capacitance internally. No external bulk or bypass capacitors are needed, simplifying PCB layout and reducing BOM count compared to SOIC-8 or TSSOP-16 variants.
What functional safety level does the MLX90377GVS-ADB-333-SP achieve?
The MLX90377GVS-ADB-333-SP is ISO 26262 ASIL-C capable for SENT output mode as a Safety Element out of Context. This means it satisfies ASIL-C requirements independently - no additional hardware or software safety mechanisms are required to meet ASIL-C when used per datasheet specifications.
What is the meaning of 'STD2 2.54' in the MLX90377GVS-ADB-333-SP ordering code?
The 'STD2 2.54' designation in MLX90377GVS-ADB-333-SP refers to the DMP-4 lead configuration: standard trim and form with 2.54 mm pitch, straight leads bent to 90° for surface-mount assembly. This matches common through-hole header spacing and ensures reliable reflow soldering in high-volume automotive production.
