Product details
Overview
MLX90377GGO-ADB-380-RE from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC designed for automotive and industrial non-contacting rotary/linear sensing. It delivers 12-bit SPC (Short PWM Code) output, operates from -40°C to 160°C, supports stray-field immune operation in Standard/Legacy Mode, and features ISO 26262 ASIL-C capability for SPC mode. It is used in throttle, pedal, and steering wheel position sensing where robust serial communication and functional safety are required.
For engineers reviewing the MLX90377GGO-ADB-380-RE datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (TSSOP-16), confirmed SPC timing (1.5 μs tick time), functional safety classification (ASIL-C for SPC), magnetic accuracy specs, and validated alternatives for position-sensing system design.
Technical Context
The MLX90377GGO-ADB-380-RE implements Triaxis® Hall sensing of Bx, By, and Bz magnetic field components to compute absolute angular or linear position without mechanical contact. Its on-chip DSP performs real-time signal conditioning, piecewise-linearization (up to 32 segments), and diagnostics, enabling high-accuracy decoding of magnet motion under varying thermal and stray-field conditions.
This variant is configured exclusively for SPC output mode with 1.5 μs tick time, fixed at factory and not reprogrammable. It uses the TSSOP-16 dual-die package for redundancy, supports 4.5–5.5 V supply in regulated mode or 6–18 V in battery mode (PWM only), and integrates reverse-polarity and overvoltage protection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Protocol | SPC (Short PWM Code) with 1.5 μs tick time - enables deterministic, low-latency position reporting compatible with automotive ECU receivers requiring short pulse coding. |
| Resolution | 12-bit (4096 steps) - provides sub-degree angular resolution or sub-millimeter linear precision in calibrated systems. |
| Operating Temp | -40°C to +160°C - qualified for under-hood automotive applications including throttle bodies and suspension modules. |
| Safety Certification | ISO 26262 ASIL-C capable for SPC output - certified as Safety Element out of Context (SEooC) for use in ASIL-C safety mechanisms. |
| Supply Range | 4.5–5.5 V (regulated) or 6–18 V (battery mode, PWM only) - supports direct connection to vehicle battery when used with PWM; SPC requires regulated supply. |
| Magnetic Sensitivity | ±1 T maximum flux density - accommodates strong magnets while maintaining linearity and immunity to external stray fields in Standard/Legacy Mode. |
| Startup Time | < 10 ms (SPC mode, after valid trigger pulse) - ensures rapid system readiness following power-up or wake-up events. |
Pinout & Package
TSSOP-16 dual-die package (GO code) with internal isolation between dies; supports full redundancy for safety-critical applications. Pins include dedicated supply, ground, decoupling, and output terminals per die, plus test and input pins reserved for Melexis calibration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VDEC1 / VDEC2 | Dedicated decoupling pins for each die - require local 100 nF ceramic capacitors to ensure stable analog/digital regulation and EMC compliance. |
| 2, 10 | VSS1 / VSS2 | Independent ground returns per die - must be connected to common system ground but kept separate on PCB until star point to maintain isolation integrity. |
| 3, 11 | VDD1 / VDD2 | Independent supply inputs per die - enable independent power sequencing and fault containment; both require 4.5–5.5 V regulated input for SPC operation. |
| 6, 15 | OUT2 / OUT1 | SPC output drivers (push-pull) - deliver synchronized 12-bit position data frames; OUT1 and OUT2 can be used for cross-checking in redundant architectures. |
| 4, 12 | Input1 / Input2 | Factory test and external measurement interface - not intended for end-user signal routing; recommended to tie to ground for EMC. |
| 5, 13 | Test2 / Test1 | Internal test access points - unused in application; must be grounded per datasheet for optimal EMC performance. |
| 7, 8, 14, 16 | N.C. | No-connect pins - electrically isolated; grounding recommended to reduce radiated emissions and improve noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall front-end | Simultaneous Bx, By, Bz sensing enables true 3D magnetic field decoding - eliminates need for external concentrators or multi-sensor assemblies in rotary/linear position systems. |
| Programmable transfer characteristic | Up to 32-point piecewise-linear (PWL) calibration - allows precise compensation of magnet nonlinearity and mechanical tolerances without host MCU intervention. |
| SPC output with 1.5 μs tick | Deterministic, low-jitter timing - meets stringent automotive timing budgets for closed-loop control (e.g., electronic throttle actuation). |
| Stray-field immunity (Standard Mode) | Robust operation under ±1 mT external interference - validated for placement near motors, solenoids, or high-current traces without shielding. |
| Dual-die TSSOP-16 redundancy | Isolated VSS/VDD/OUT per die with >4 MΩ inter-die resistance - supports ASIL-D decomposition via hardware redundancy and cross-monitoring. |

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-330-RE | SENT output (3 μs tick), same TSSOP-16 package, identical ASIL-C qualification and Triaxis® core. | Requires SENT-capable ECU receiver; higher protocol overhead than SPC but supports richer diagnostic data embedding. | Select when ECU already implements SENT stack and diagnostic message bandwidth exceeds SPC capacity. |
| MLX90377GDC-ADB-380-RE | Same SPC output mode and firmware, but SOIC-8 single-die package (no redundancy), lower temperature grade (-40°C to +150°C). | Lacks dual-die isolation and ASIL-D decomposition capability; suitable for non-redundant, cost-sensitive applications. | Choose for space-constrained PCBs where redundancy is not mandated and thermal margin permits SOIC-8 use. |
Compared with MLX90377GGO-ADB-330-RE, the MLX90377GGO-ADB-380-RE offers lower latency and simpler ECU interface via SPC; compared with MLX90377GDC-ADB-380-RE, it provides full hardware redundancy and extended temperature range essential for safety-critical under-hood deployment.
