Product details

Overview

MLX90377GGO-ADB-380-SP from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC in TSSOP-16 dual-die package, delivering 12-bit SPC (Short PWM Code) output with 1.5 μs tick time, ASIL-C functional safety capability for SPC mode, and operation over −40 °C to +160 °C. It decodes absolute rotary or linear magnet position via B_x, B_y, B_z field components and supports stray-field immune configurations.

For engineers reviewing the MLX90377GGO-ADB-380-SP datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping, confirmed SPC timing and diagnostic behavior, ASIL-C safety scope, real-world automotive use cases, and validated alternative options for position-sensing system design.

Technical Context

The MLX90377GGO-ADB-380-SP implements a dual-die TSSOP-16 architecture with isolated ground and supply domains (VSS1/VDD1 and VSS2/VDD2), enabling redundancy-critical applications. Its Triaxis® front end captures all three orthogonal magnetic flux components, processed by an on-chip DSP with programmable piecewise-linear transfer characteristics (up to 32 segments) and configurable filtering.

It operates exclusively in SPC output mode per ADB-380 configuration-no runtime reprogramming-and features SENT/SPC-compliant error reporting, 48-bit ID, and passive broken-wire diagnostics for both VDD and VSS. The device uses internal analog and digital regulators, reverse-polarity protection, and operates from 4.5 V to 18 V battery supply.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Protocol	SPC (Short PWM Code) with 1.5 μs tick time - fixed by ADB-380 option code; not user-reprogrammable.
Functional Safety	ISO 26262 ASIL-C capable for SPC output mode (Safety Element out of Context); requires external safety manager.
Operating Temp	−40 °C to +160 °C - qualified for under-hood automotive environments including throttle and pedal sensors.
Supply Range	4.5 V to 18 V - supports direct vehicle battery connection with integrated reverse-voltage and overvoltage protection.
Resolution	12-bit angular/linear position - enables ≤0.1° or ≤0.025 mm precision depending on magnet geometry and calibration.
Package	TSSOP-16 dual-die - provides galvanic isolation (≥4 MΩ between dice) for fault-tolerant redundant sensing.
Diagnostic Coverage	Passive broken-wire detection for VDD and VSS, plus active CRC-checked SPC status nibbles with error codes.

Pinout & Package

TSSOP-16 dual-die package with isolated supply/ground domains per die and dedicated decoupling pins. Unused pins (N.C., Test) must be connected to ground for optimal EMC performance.

Pin/Terminal	Circuit Role	Design Meaning
1, 9	VDEC1 / VDEC2	Dedicated decoupling pins for each die - require local 100 nF ceramic capacitors to VSS1/VSS2 respectively.
2, 10	VSS1 / VSS2	Isolated ground returns - no internal connection between dice; critical for redundancy integrity.
3, 11	VDD1 / VDD2	Independent supply inputs - enable independent power domain monitoring and fault containment.
4, 12	Input1 / Input2	Test/measurement interface - not used in standard operation; tied to ground if unused.
5, 13	Test2 / Test1	Factory test access - reserved for Melexis; connect to ground per EMC recommendation.
6, 15	OUT2 / OUT1	SPC output drivers - push-pull, 12-bit resolution, 1.5 μs tick time; support open-drain configuration.
7, 8, 14, 16	N.C.	No internal connection - must be grounded to minimize EMI and ensure signal integrity.

Key Features

Feature	Design Value
Triaxis® 3D Hall Sensing	Simultaneous B_x, B_y, B_z measurement enables true absolute position decoding without mechanical stops or multi-turn ambiguity.
SPC Output Compliance	Meets SAE J2716 APR2016 SPC specification with 1.5 μs tick time, status nibble, and CRC-protected data frames.
Dual-Die Redundancy	Galvanically isolated dice in single TSSOP-16 package provide hardware-level fault tolerance for ASIL-C systems.
Programmable Transfer Curve	Up to 32-point piecewise-linear calibration allows precise linearization across non-ideal magnet trajectories (e.g., steering wheel).
Stray-Field Immunity	Configured for Standard/Legacy Mode (ADB-380), offering robustness against external magnetic interference up to ±1 T.
Integrated Diagnostics	Passive broken-wire detection (VDD/VSS) and active SPC status nibble reporting enable real-time health monitoring without host CPU overhead.

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-SP	SENT output (3 μs tick time) instead of SPC; identical dual-die TSSOP-16 package and ASIL-C capability.	Requires SENT-capable ECU interface; supports richer diagnostic messaging (e.g., multiple status nibbles) but higher protocol overhead.	Select when host microcontroller has SENT receiver IP and system demands extended diagnostic coverage beyond SPC.
MLX90371GGO-ADB-080-SP	Single-die TSSOP-16, 12-bit SPC output, ASIL-B rated; lacks dual-die isolation and full ASIL-C support.	Suitable for non-redundant applications like HVAC flaps or seat position where ASIL-C is not mandated.	Choose for cost-sensitive, non-safety-critical linear/rotary sensing where galvanic isolation is unnecessary.

Compared with MLX90377GGO-ADB-380-SP, the ADB-330 variant offers deeper diagnostic framing at the cost of ECU interface compatibility, while the MLX90371 provides SPC functionality in a lower-cost, ASIL-B single-die form factor - neither is pin-compatible nor drop-in replaceable due to differing safety architecture and die count.

FAQ

What output protocol does the MLX90377GGO-ADB-380-SP support?

The MLX90377GGO-ADB-380-SP supports only SPC (Short PWM Code) output with a fixed 1.5 μs tick time, as defined by the ADB-380 option code. This configuration is factory-programmed and cannot be changed in the field. The SPC frame includes status and communication nibbles with CRC protection, enabling robust diagnostics in noisy automotive environments. MLX90377GGO-ADB-380-SP does not support SENT, PWM, or analog modes.

Is the MLX90377GGO-ADB-380-SP pin-compatible with other MLX90377 variants in TSSOP-16?

Yes, all MLX90377 variants in TSSOP-16 (GO package code) share identical pinout and footprint, including MLX90377GGO-ADB-380-SP. Pin assignments for VDD1/VSS1/VDEC1/OUT1 and VDD2/VSS2/VDEC2/OUT2 are standardized across ADB-300 through ADB-380 and ADB-5xx codes. However, functional differences - such as output protocol, safety rating, and stray-field immunity mode - require matching firmware and system-level validation.

Does the MLX90377GGO-ADB-380-SP meet ISO 26262 ASIL-C requirements?

Yes, the MLX90377GGO-ADB-380-SP is ISO 26262 ASIL-C capable for SPC output mode as a Safety Element out of Context (SEooC). This means it satisfies ASIL-C requirements for fault detection, diagnostics, and safe state behavior when integrated into a compliant system architecture with appropriate safety manager. MLX90377GGO-ADB-380-SP achieves this via dual-die isolation, CRC-protected SPC frames, and passive broken-wire detection.

What is the purpose of the dual-die architecture in the MLX90377GGO-ADB-380-SP?

The dual-die architecture in the MLX90377GGO-ADB-380-SP provides galvanic isolation between two independent sensing channels (≥4 MΩ isolation resistance), enabling hardware-level redundancy for functional safety. Each die has its own VDD/VSS/VDEC/OUT path, allowing independent power monitoring and fault containment. This structure supports ASIL-C decomposition in systems requiring fail-operational or fail-safe behavior, such as electric power steering or brake-by-wire.

Can the MLX90377GGO-ADB-380-SP be used in linear position sensing applications?

Yes, the MLX90377GGO-ADB-380-SP supports both absolute rotary and linear position sensing via Triaxis® 3D Hall technology. When paired with a properly designed linear magnet arrangement (e.g., moving pole pair or gradient field), it delivers 12-bit resolution linear displacement output in SPC format. Application examples include pedal position, ride height, and float-level sensing - all validated in Melexis documentation and supported by programmable transfer curve calibration.
