Product details
Overview
MLX90377GGO-ADB-530-RE from Melexis is a Triaxis® monolithic magnetic position sensor IC for absolute rotary position sensing in high-field stray-field immune configurations. It delivers 12-bit SENT output with 3 μs tick time, operates from -40°C to +160°C, and uses TSSOP-16 dual-die packaging for ASIL-C functional safety compliance in automotive pedal and throttle position systems.
For engineers reviewing the MLX90377GGO-ADB-530-RE datasheet, pinout, applications, or equivalent options, key selection criteria include its Rotary Stray-Field Immune Mode (High Field variant), SENT protocol conformance to SAE J2716 APR2016, and dual-die isolation for redundancy-critical motion control.
Technical Context
The MLX90377GGO-ADB-530-RE implements Triaxis® Hall sensing of Bx, By, and Bz magnetic components to decode absolute angular position without contact. Its DSP-based signal conditioning supports programmable piecewise-linear transfer characteristics (up to 32 segments) and real-time diagnostics including broken-wire detection on VDD and VSS.
This variant is configured exclusively for SENT output mode (3 μs tick time), operates in Rotary Stray-Field Immune Mode (High Field variant), and requires no end-user reprogramming to switch protocols - output mode is fixed at manufacture per ADB-530 option code.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Output Protocol | SENT (SAE J2716 APR2016), 3 μs tick time - enables secure, error-coded serial transmission with status nibbles for ECU-level fault reporting. |
| Operating Temperature | -40°C to +160°C - supports under-hood automotive placement without external thermal derating. |
| Supply Voltage Range | 4.5 V to 5.5 V (regulated) or 6 V to 18 V (battery) - accommodates both regulated MCU supply and direct vehicle battery connection. |
| Functional Safety | ISO 26262 ASIL-C capable (SENT mode) as Safety Element out of Context - meets requirements for high-integrity pedal/throttle position feedback loops. |
| Magnetic Sensing | Triaxis® 3-axis Hall front-end - resolves absolute angle from rotating magnet field vector, enabling non-contact, wear-free position measurement. |
| Accuracy | ±0.5° typical total error (rotary mode, -40°C to +150°C) - ensures precise closed-loop control in steering wheel and ride height applications. |
| Package | TSSOP-16 dual-die - provides galvanic isolation (>4 MΩ between dice) for redundant signal paths and enhanced fault tolerance. |
Pinout & Package
TSSOP-16 package with dual-die architecture: two independent sensor dies sharing mechanical footprint but electrically isolated, supporting redundancy-critical automotive functions. Pins include dedicated supply/ground per die, decoupling pins, test inputs, and separate output terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDEC1 / VDEC2 | Decoupling capacitor connection (per die) | Stabilizes internal analog/digital regulators; requires 100 nF ceramic capacitor close to each pin. |
| VSS1 / VSS2 | Ground reference (per die) | Independent ground return paths prevent cross-die noise coupling; must be connected to system ground with low-inductance routing. |
| VDD1 / VDD2 | Power supply input (per die) | Enables independent power domain control; supports fail-safe shutdown of one die while other remains active. |
| OUT1 / OUT2 | Digital output (per die) | Two independent SENT outputs - used for cross-checking or voting logic in ASIL-C systems. |
| Input1 / Input2 | External measurement/test interface | Allows factory calibration or diagnostic injection; not intended for end-user signal routing. |
| Test1 / Test2 | Internal test access | Reserved for Melexis production testing; must be tied to ground for optimal EMC performance. |
| N.C. | No connect | Unused pins (pins 7, 8, 14, 16); recommended to tie to ground to minimize parasitic antenna effects. |
Key Features
| Feature | Design Value |
|---|---|
| Rotary Stray-Field Immune Mode (High Field) | Rejects interference from nearby motors or solenoids up to ±1 T, enabling robust operation in dense powertrain environments. |
| SENT Output with Status Nibble | Delivers 12-bit position plus CRC-protected diagnostic data (e.g., temperature, supply voltage, internal faults) in every frame. |
| Dual-Die Isolation | Galvanic isolation >4 MΩ between dice ensures single-point failure cannot compromise both outputs - required for ASIL-C redundancy. |
| Programmable Transfer Characteristic | Up to 32-piecewise linear segments allow precise mapping of magnet rotation to output code, eliminating external lookup tables. |
| Broken-Wire Detection | Monitors continuity of VDD and VSS lines independently per die; reports open-circuit faults via SENT status nibble without interrupting position output. |

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 | Same TSSOP-16 package and temperature range, but Standard/Legacy Mode (not Rotary Stray-Field Immune); SENT output with identical 3 μs tick time. | Lacks high-field stray immunity; suitable for less electromagnetically noisy locations like HVAC flaps or seat position. | Select when cost optimization is prioritized over stray-field resilience and ASIL-C certification is not required. |
| MLX90377GDC-ADB-530-RE | Same Rotary Stray-Field Immune (High Field) mode and SENT output, but SOIC-8 single-die package instead of TSSOP-16 dual-die. | No galvanic isolation or redundancy; lower ASIL capability (ASIL-B max) due to single-die architecture. | Choose for space-constrained non-redundant applications where PCB area is critical and dual-output voting is unnecessary. |
Compared with MLX90377GGO-ADB-330-RE and MLX90377GDC-ADB-530-RE, the MLX90377GGO-ADB-530-RE uniquely combines high-field stray immunity, dual-die isolation, and ASIL-C compliance - making it the only option qualified for safety-critical throttle and brake pedal sensing where magnetic interference and fault tolerance are co-constrained.

FAQ
What output protocol does the MLX90377GGO-ADB-530-RE support?
The MLX90377GGO-ADB-530-RE supports SENT output only, conforming to SAE J2716 APR2016 with a fixed 3 μs tick time. It does not support analog, PWM, or SPC modes - this is hard-coded by the ADB-530 option and cannot be changed via programming or configuration.
Is the MLX90377GGO-ADB-530-RE 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-530-RE. However, electrical behavior differs: ADB-530 enables Rotary Stray-Field Immune Mode and SENT-only operation, while ADB-330 uses Standard Mode with SENT - requiring different magnetic circuit design and calibration.
Does the MLX90377GGO-ADB-530-RE meet ISO 26262 ASIL-C requirements?
Yes, the MLX90377GGO-ADB-530-RE is certified ASIL-C capable for SENT output mode as a Safety Element out of Context (SEooC), with documented safety mechanisms including CRC protection, internal diagnostics, and dual-die fault containment - verified per ISO 26262-5 and -10 for automotive safety applications.
What is the purpose of the dual-die architecture in the MLX90377GGO-ADB-530-RE?
The dual-die TSSOP-16 implementation in MLX90377GGO-ADB-530-RE provides galvanically isolated signal paths (VSS1/VSS2, VDD1/VDD2, OUT1/OUT2), enabling hardware-level redundancy. This allows cross-checking of position data or voting logic in ASIL-C systems, where failure of one die does not compromise the second die's output integrity.
Can the MLX90377GGO-ADB-530-RE be used in linear position sensing applications?
No - the MLX90377GGO-ADB-530-RE is configured exclusively for Rotary Stray-Field Immune Mode (High Field variant), optimized for angular position decoding from rotating magnets. For linear sensing, Melexis specifies Linear Stray-Field Immune variants (e.g., ADB-2xx codes), which use different internal calibration and magnetic circuit assumptions.
