Product details
Overview
MLX90377GGO-ADB-300-TU from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC for rotary or linear non-contact sensing. It delivers 12-bit ratiometric analog or PWM output in Standard/Legacy Mode, operates from -40°C to 160°C, supports stray-field robust magnetic configurations, and is qualified for automotive pedal/throttle position sensing per ISO 26262 ASIL-B (analog mode).
For engineers reviewing the MLX90377GGO-ADB-300-TU datasheet, pinout, applications, or equivalent options, key selection factors include its TSSOP-16 dual-die package, programmable linear transfer characteristic (4/8/16/32-point PWL), SENT/PWM/SPC/analog output configurability, and ASIL-B safety capability in analog mode.
Technical Context
The MLX90377GGO-ADB-300-TU integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, enabling absolute angular (0–360°) or linear position decoding with appropriate magnet geometry. Its on-chip DSP performs real-time signal conditioning, including programmable piecewise-linearization and filtering.
This variant uses the TSSOP-16 package (GO code), implements Standard/Legacy Mode (ADB-300), and configures low-power analog/PWM output. It does not support SENT or SPC protocols - those require ADB-330 or ADB-380 options - and lacks full redundancy features enabled only in dual-die configurations with independent diagnostics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Mode | Analog ratiometric and PWM; fixed at factory via ADB-300 option - not reprogrammable in-system. |
| Resolution | 12-bit effective resolution for both analog and PWM outputs, enabling ≤0.1° angular or sub-millimeter linear position accuracy. |
| Operating Temp | -40°C to +160°C ambient, supporting under-hood automotive placement without external thermal derating. |
| Supply Voltage | 4.5 V to 5.5 V (regulated supply); supports 6–18 V battery operation only in PWM mode per datasheet Section 6. |
| Supply Current | 8–11.5 mA typical in Legacy Mode (ADB-300), enabling low-power ECU subsystem integration. |
| Safety Rating | ISO 26262 ASIL-B capable for analog output mode as Safety Element out of Context (SEooC). |
| Magnetic Sensing | Triaxis® 3-axis Hall front end enables absolute position measurement without mechanical contact or wear-prone potentiometers. |
Pinout & Package
TSSOP-16 package (GO code) with dual-die layout optimized for functional safety redundancy; requires external decoupling capacitors on VDEC1/VDEC2 pins and ground connection for all N.C. and Test pins per EMC best practice.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDEC1 | Decoupling pin die1 | Must be connected to 100 nF ceramic capacitor to VSS1 for stable analog/digital power rail filtering on first die. |
| VSS1 | Ground die1 | Primary ground reference for die1; must be low-inductance path to system ground plane. |
| VDD1 | Supply die1 | 4.5–5.5 V regulated supply input for die1; shares voltage domain with VDD2 in single-supply configuration. |
| Input1 | Test/external measurement | Factory test access; not intended for end-user signal routing or functional use in production design. |
| Test2 | Factory test | Dedicated test interface for die2; must be tied to VSS for EMC compliance and noise immunity. |
| OUT2 | Output die2 | Second independent output channel for redundant sensing; configured identically to OUT1 in ADB-300 mode. |
| N.C. | Not connected | No internal connection; tie to VSS to minimize parasitic antenna effects and improve EMC performance. |
| VDEC2 | Decoupling pin die2 | Requires separate 100 nF ceramic capacitor to VSS2 to isolate die2 power domain from die1. |
| VSS2 | Ground die2 | Independent ground reference for die2; recommended to route separately to avoid ground loop coupling. |
| VDD2 | Supply die2 | Identical supply requirements as VDD1; shared supply acceptable but dual-supply improves fault isolation. |
| Input2 | Test/external measurement | Redundant test access for die2; unused in application and must be grounded. |
| Test1 | Factory test | Die1 test interface; connect to VSS to prevent floating node and ensure predictable startup behavior. |
| OUT1 | Output die1 | Main analog/PWM output channel; electrically identical to OUT2 for cross-checking in safety-critical systems. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Enables absolute position detection from a single moving magnet without mechanical linkage or gear trains. |
| Programmable PWL Transfer | Supports 4-, 8-, 16-, or 32-point piecewise-linear calibration to correct for magnet nonlinearity and mechanical tolerances. |
| Stray-Field Immunity | Configurable via magnetic mode selection (ADB-300 = Standard/Legacy), reducing sensitivity to external EMI sources near engine compartments. |
| Dual-Die Redundancy | TSSOP-16 package provides two independent sensor dies with separate power/ground paths for ASIL-B diagnostic coverage. |
| Ratiometric Analog Output | Output scales directly with VDD, eliminating need for precision voltage references and simplifying ADC interfacing in microcontrollers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GDC-ADB-300-RE | SOIC-8 single-die package; no dual-die redundancy; lower pin count; no isolation between dies. | Targeted at cost-sensitive non-safety-critical applications where ASIL-B is not required. | Select when footprint constraints favor SOIC-8 and functional safety diagnostics are handled externally. |
| MLX90377GVS-ADB-300-RE | DMP-4 PCB-less package with straight leads; integrated decoupling capacitors; 4-pin footprint; no test pins. | Optimized for space-constrained modules requiring minimal board area and simplified layout. | Choose for compact motor control or HVAC actuators where TSSOP-16 routing complexity must be avoided. |
Compared with MLX90377GGO-ADB-300-TU, the SOIC-8 alternative sacrifices dual-die fault tolerance for lower cost and smaller footprint, while the DMP-4 version trades pin count and test access for ultra-compact integration and built-in capacitance - all retain identical analog/PWM functionality and ADB-300 configuration.

FAQ
What output protocols does the MLX90377GGO-ADB-300-TU support?
The MLX90377GGO-ADB-300-TU supports only analog ratiometric and PWM output modes, as defined by its ADB-300 option code. SENT and SPC protocols are not available on this variant - they require ADB-330 or ADB-380 ordering codes and cannot be enabled via programming after manufacture.
Is the MLX90377GGO-ADB-300-TU pin-compatible with other MLX90377 package variants?
No - the MLX90377GGO-ADB-300-TU uses the TSSOP-16 package with 16 pins and dual-die layout, whereas SOIC-8 (8-pin), DMP-4 (4-pin), and SMP-3 (3-pin) variants have entirely different pin counts, functions, and physical footprints. Direct PCB replacement is not possible without redesign.
Does the MLX90377GGO-ADB-300-TU support ISO 26262 functional safety certification?
Yes - the MLX90377GGO-ADB-300-TU is ISO 26262 ASIL-B capable for analog output mode as a Safety Element out of Context (SEooC). It achieves this through dual-die architecture, built-in diagnostics, and failure mode analysis documented in Melexis' safety manual, but full system-level ASIL-B compliance requires integration into a certified safety framework.
Can the transfer characteristic of the MLX90377GGO-ADB-300-TU be customized in the field?
No - the MLX90377GGO-ADB-300-TU's transfer function (e.g., 4-point or 32-point PWL) is programmed during final test at Melexis and locked in NVRAM. End users cannot modify it post-delivery; customization must be specified at order time via the ADB option code.
What is the maximum magnetic field range supported by the MLX90377GGO-ADB-300-TU?
The MLX90377GGO-ADB-300-TU operates within ±1 T (±10,000 Gauss) magnetic flux density per datasheet Table 8. Its Standard/Legacy Mode (ADB-300) is optimized for typical automotive magnet strengths (0.1–0.5 T), and exceeding ±1 T risks permanent sensor damage or parametric shift.
