Product details
Overview
MLX90377GGO-ADB-210-SP from Melexis is a monolithic Triaxis® Hall-based magnetic position sensor IC designed for absolute rotary or linear position sensing in harsh automotive environments. It delivers 12-bit resolution analog and PWM outputs, operates from -40°C to +160°C, supports Linear Stray-Field Immune Mode, and is ASIL-B capable for analog output - used in throttle, pedal, and ride height sensing.
For engineers reviewing the MLX90377GGO-ADB-210-SP datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (TSSOP-16), confirmed stray-field immunity mode, real-world timing specs (startup < 5 ms in High Speed Mode), functional safety classification (ASIL-B), and validated alternative options for automotive position sensing designs.
Technical Context
The MLX90377GGO-ADB-210-SP implements Triaxis® technology to measure all three orthogonal magnetic field components (Bx, By, Bz), enabling robust absolute angle or linear displacement decoding without mechanical contact. Its on-chip DSP performs real-time piecewise-linearization (up to 32 segments) and programmable transfer characteristics.
This variant uses the TSSOP-16 dual-die package with isolated ground/supply domains (Risol ≥ 4 MΩ), supports only Analog/PWM output in High Speed Mode (no SENT/SPC), and features factory-programmed Linear Stray-Field Immune operation - optimized for magnet configurations where external field interference must be rejected while maintaining high accuracy over full stroke.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Resolution | 12-bit effective resolution for analog and PWM outputs - enables ±0.1° angular accuracy or sub-0.1 mm linear precision in calibrated systems. |
| Operating Temperature | -40°C to +160°C - qualified for under-hood and transmission-mounted automotive applications without derating. |
| Supply Voltage Range | 4.5 V to 5.5 V (regulated) or 6 V to 18 V (battery) - supports direct connection to vehicle battery with reverse polarity protection up to -18 V. |
| Startup Time | < 5 ms in High Speed Mode - ensures rapid system readiness after ignition, critical for drivetrain control loops. |
| Functional Safety | ISO 26262 ASIL-B capable for analog output - certified as Safety Element out of Context (SEooC) with documented fault handling time interval < 100 ms. |
| Magnetic Immunity | Linear Stray-Field Immune Mode (-2xx option code) - rejects uniform external fields up to ±100 mT while preserving sensitivity to target magnet motion. |
| Output Modes | Analog ratiometric (0.5–4.5 V) and PWM (10–90% duty cycle) - both configurable for high-speed response with no protocol switching required. |
Pinout & Package
TSSOP-16 dual-die package with internal isolation between die1 and die2; requires separate decoupling (VDEC1/VDEC2), supply (VDD1/VDD2), and ground (VSS1/VSS2) connections per die. Unused pins (N.C., Test) must be tied to ground for EMC compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VDEC1 / VDEC2 | Dedicated decoupling terminals per die - mandatory 100 nF ceramic capacitor placement adjacent to each pin for stable analog/digital regulation. |
| 2, 10 | VSS1 / VSS2 | Isolated ground returns - must not be shorted externally; enables differential diagnostics and fault containment between dies. |
| 3, 11 | VDD1 / VDD2 | Independent supply inputs - allow independent power sequencing and support redundancy architectures with separate voltage rails. |
| 6, 15 | OUT2 / OUT1 | Push-pull PWM/analog outputs - electrically isolated; support dual-signal validation or hot-swap failover in safety-critical systems. |
| 4, 12 | Input1 / Input2 | Factory test access points - not intended for end-user signal routing; leave unconnected or tie to ground per layout guidelines. |
| 5, 13, 7, 8, 14, 16 | Test1 / Test2 / N.C. | No-connect or internal test terminals - must be connected to VSS for optimal EMC performance per datasheet Section 3.2. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Magnetic Sensing | Simultaneous Bx, By, Bz measurement enables single-chip absolute position decoding without external concentrators or multi-sensor fusion. |
| Linear Stray-Field Immunity | Factory-configured rejection of uniform external magnetic fields - eliminates need for shielding or compensation algorithms in EMI-heavy zones. |
| Programmable Transfer Characteristic | Up to 32-point piecewise-linear calibration stored in NVRAM - allows precise matching to non-linear mechanical travel (e.g., throttle cam profiles). |
| Dual-Die Redundancy (TSSOP-16) | Electrically isolated dies with independent supplies/grounds - supports ASIL-D system-level fault tolerance via cross-checking or voting logic. |
| High-Speed Analog/PWM Output | Sub-5 ms startup and ≤ 100 µs latency - meets real-time control requirements for engine management and brake-by-wire systems. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90371GGO-ADB-210-SP | Single-die TSSOP-16 variant with identical Linear Stray-Field Immune Mode and Analog/PWM outputs, but lacks dual-die isolation and ASIL-C capability. | Suitable for ASIL-B systems requiring same magnetic immunity but lower cost and smaller footprint; not approved for dual-channel redundancy. | Select when system-level fault tolerance is handled externally and board space is constrained. |
| TLV493DW2B6HTSA1 | Infineon 3D Hall sensor with I²C interface, 12-bit resolution, and -40°C to +125°C rating - no stray-field immunity mode or ASIL certification. | Used in consumer/industrial position feedback where automotive qualification and field immunity are not required. | Choose for cost-sensitive non-automotive designs needing digital interface and simpler programming model. |
Compared with MLX90377GGO-ADB-210-SP, the MLX90371 offers reduced safety certification scope and no die isolation, while the TLV493D lacks temperature rating, stray-field rejection, and functional safety documentation - making MLX90377GGO-ADB-210-SP the only option qualified for ASIL-B linear position sensing in 160°C environments with field immunity.

FAQ
What output protocols does the MLX90377GGO-ADB-210-SP support?
The MLX90377GGO-ADB-210-SP supports only analog ratiometric and PWM outputs in High Speed Mode, as defined by its ADB-210 option code. SENT and SPC protocols are disabled in this variant - they require different option codes (e.g., ADB-230 or ADB-280) and cannot be enabled via reprogramming. The MLX90377GGO-ADB-210-SP delivers 12-bit resolution on both outputs with sub-5 ms startup time.
Is the MLX90377GGO-ADB-210-SP pin-compatible with other MLX90377 variants in TSSOP-16?
Yes, all MLX90377 variants in TSSOP-16 (GO package code) share identical pinout and mechanical footprint per datasheet Section 3.2. The MLX90377GGO-ADB-210-SP uses pins 1 (VDEC1), 2 (VSS1), 3 (VDD1), 6 (OUT2), 9 (VDEC2), 10 (VSS2), 11 (VDD2), and 15 (OUT1) - with all other pins designated N.C. or Test and requiring grounding per EMC guidelines.
How does Linear Stray-Field Immunity work in the MLX90377GGO-ADB-210-SP?
The MLX90377GGO-ADB-210-SP implements factory-programmed Linear Stray-Field Immune Mode (option code "2") that digitally cancels uniform external magnetic fields up to ±100 mT while preserving sensitivity to the target magnet's axial motion. This is achieved through on-chip differential signal processing of Triaxis® Bx/By/Bz measurements - no external shielding or calibration is needed for operation near motors or solenoids.
What functional safety level is certified for the MLX90377GGO-ADB-210-SP?
The MLX90377GGO-ADB-210-SP is ISO 26262 ASIL-B capable for analog output mode and classified as a Safety Element out of Context (SEooC). Its fault handling time interval is <100 ms, and it includes built-in diagnostics such as broken-wire detection on VDD/VSS and internal watchdog timers - all documented in the Melexis Safety Manual for MLX90377.
Can the MLX90377GGO-ADB-210-SP be used in dual-die redundancy architectures?
Yes - the MLX90377GGO-ADB-210-SP is packaged in TSSOP-16 with electrically isolated die1 and die2, including separate VDD/VSS/VDEC domains and independent OUT1/OUT2 outputs. This enables hardware-level redundancy for ASIL-D systems when combined with external voting logic or cross-monitoring, as supported by its ≥4 MΩ inter-die isolation resistance.
