Product details
Overview
MLX90377GGO-ADB-330-TU from Melexis is a Triaxis® monolithic 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 features ASIL-C functional safety compliance for SENT mode. Used in automotive throttle and pedal position sensing where stray-field immunity and protocol reliability are critical.
For engineers reviewing the MLX90377GGO-ADB-330-TU datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (TSSOP-16), SENT timing parameters, ASIL-C safety architecture, magnetic accuracy specs per SAE J2716 APR2016, and validated alternative options for automotive position-sensing designs.
Technical Context
The MLX90377GGO-ADB-330-TU implements Triaxis® Hall sensing of Bx, By, and Bz magnetic components to compute absolute angular or linear position without mechanical contact. Its on-chip DSP supports programmable piecewise-linear transfer characteristics (up to 32 segments) and real-time signal conditioning for robust operation under EMI and thermal stress.
This variant is configured exclusively for SENT output (3 μs tick time), uses the TSSOP-16 dual-die package for redundancy, and meets ISO 26262 ASIL-C requirements as a Safety Element out of Context. It does not support analog, PWM, or SPC modes - output protocol is fixed at factory via ADB-330 option code.
Key Specifications

| Package | TSSOP-16 dual-die - provides physical redundancy and >4 MΩ isolation between dies for fault-tolerant system design. |
Pinout & Package
TSSOP-16 package with dual-die architecture for functional redundancy and die-to-die isolation. Pins include dedicated supply/ground pairs per die, independent outputs, and decoupling terminals for EMC-optimized layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VDEC1 / VDEC2 | Dedicated decoupling pins per die - require local 100 nF ceramic capacitors to minimize noise coupling between sensor dies. |
| 2, 10 | VSS1 / VSS2 | Independent ground returns per die - maintain isolation integrity; must not be shorted externally. |
| 3, 11 | VDD1 / VDD2 | Separate supply inputs per die - enable independent power sequencing and fault containment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GGO-ADB-310-TU | Same TSSOP-16 package and temperature range, but configured for high-speed PWM output instead of SENT. | Used where ECU lacks SENT receiver but requires fast position updates (e.g., legacy powertrain controllers). | Select when PWM interface compatibility outweighs ASIL-C certification needs. |
| MLX90377GDC-ADB-330-TU | Identical SENT configuration and firmware, but in SOIC-8 single-die package - no die isolation or redundancy. | Suitable for non-safety-critical applications like HVAC flap control or seat position where cost and footprint are prioritized. | Choose for cost-sensitive designs where ASIL-C is not mandated and board space permits SOIC-8. |
Compared with MLX90377GGO-ADB-330-TU, the ADB-310 variant trades SENT protocol compliance and ASIL-C capability for faster PWM response, while the ADB-330 in SOIC-8 retains identical functionality but removes hardware-level redundancy - making the TSSOP-16 dual-die version uniquely suited for fault-tolerant automotive safety systems.
