Product details
Overview
MLX90377GGO-ADB-210-RE from Melexis is a Triaxis® monolithic magnetic position sensor IC for absolute linear position sensing with stray-field immunity, 12-bit analog/PWM output, high-speed mode, and ASIL-B functional safety compliance. It operates from -40°C to 160°C in TSSOP-16 package and delivers robust non-contact sensing in automotive pedal and throttle systems.
For engineers reviewing the MLX90377GGO-ADB-210-RE datasheet, pinout, applications, or equivalent options, key selection criteria include its Linear Stray-Field Immune Mode, dual-die isolation, SENT/PWM/SPC/analog protocol support, and ISO26262 ASIL-B qualification for analog output.
Technical Context
The MLX90377GGO-ADB-210-RE implements Triaxis® Hall technology to measure all three magnetic field components (Bx, By, Bz), enabling precise decoding of magnet position without mechanical contact. Its on-chip DSP performs real-time signal conditioning and piecewise-linearization (up to 32 segments) for high-accuracy absolute position output.
This variant is configured in Linear Stray-Field Immune Mode (-2xx option code), supports high-speed analog/PWM output (–210), and resides in the TSSOP-16 dual-die package (GO code) with 4 MΩ inter-die isolation resistance. It uses a 12 MHz main clock with ±3.5% total drift and delivers 12-bit resolution across all output modes.
Key Specifications

Pinout & Package
TSSOP-16 dual-die package with 4 MΩ isolation between dies; designed for redundancy-critical automotive applications requiring fault-tolerant position feedback.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDEC1 | Decoupling pin die1 | Stabilizes internal analog regulator for die 1; requires 100 nF ceramic capacitor to VSS1. |
| VSS1 | Ground die1 | Reference return path for die 1; must be low-inductance connection to minimize noise coupling. |
| VDD1 | Supply die1 | Primary power input for die 1; accepts 4.5–18 V with reverse polarity protection to –18 V. |
| Input1 | Test/external measurement | Factory test access; not intended for end-user signal routing. |

| OUT2 | Output die2 | Redundant output channel for die 2; supports same protocols as OUT1 (analog/PWM/SENT/SPC). |
| N.C. | Not connected | Unused pins (7, 8, 14, 16); recommended to tie to ground for EMC performance. |
| VDEC2 | Decoupling pin die2 | Stabilizes internal analog regulator for die 2; requires separate 100 nF capacitor to VSS2. |
| VSS2 | Ground die2 | Independent ground reference for die 2; isolated from VSS1 per ISO26262 redundancy requirements. |
| VDD2 | Supply die2 | Independent power input for die 2; enables true dual-channel power domain separation. |

| OUT1 | Output die1 | Main output channel for die 1; electrically identical to OUT2 and configurable via NVRAM. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Measures Bx, By, Bz simultaneously to resolve absolute position from magnet motion - eliminates need for multi-sensor assemblies in rotary/linear systems. |

FAQ
What output protocols does the MLX90377GGO-ADB-210-RE support?
The MLX90377GGO-ADB-210-RE supports analog ratiometric, PWM, SENT (SAE J2716 APR2016), and SPC output protocols. Its Linear Stray-Field Immune Mode (-210 option code) configures it for high-speed analog/PWM operation. Protocol selection is fixed at manufacture and cannot be reprogrammed in the field - each variant must be ordered with the correct ADB code.
Is the MLX90377GGO-ADB-210-RE qualified for automotive safety standards?
Yes, the MLX90377GGO-ADB-210-RE is ISO26262 ASIL-B qualified for analog output mode and ASIL-C capable for SENT, PWM, and SPC outputs as a Safety Element out of Context (SEooC). Its TSSOP-16 dual-die architecture provides 4 MΩ inter-die isolation, enabling redundant position reporting required for higher integrity systems.
How does the Linear Stray-Field Immune Mode benefit the MLX90377GGO-ADB-210-RE in real applications?
The Linear Stray-Field Immune Mode in the MLX90377GGO-ADB-210-RE actively rejects external magnetic interference up to ±1 T, ensuring accurate linear position measurement in environments with adjacent motors, solenoids, or high-current wiring. This is validated for use in EV pedal modules and chassis control units where conventional Hall sensors fail.
What is the pin configuration difference between MLX90377GGO-ADB-210-RE and SOIC-8 variants?
The MLX90377GGO-ADB-210-RE uses a TSSOP-16 dual-die package with fully independent power, ground, and output pins for each die (VDD1/VSS1/OUT1 and VDD2/VSS2/OUT2), whereas SOIC-8 variants like MLX90377GDC-ADB-210-RE use a single-die 8-pin layout. The TSSOP-16 enables true hardware redundancy and meets ASIL-C architectural requirements.
Can the MLX90377GGO-ADB-210-RE be used in battery-powered 12 V systems?
Yes, the MLX90377GGO-ADB-210-RE supports 6 V to 18 V supply operation in battery mode, specifically optimized for PWM output. Its reverse voltage protection down to –18 V and operating range up to +160°C make it suitable for direct connection to vehicle battery rails in throttle and pedal modules without external regulators.
