Product details
Overview
MLX90377GVE-ADB-210-TU from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC for linear stray-field immune applications, delivering 12-bit analog and PWM outputs with high-speed mode timing, operating from -40°C to +160°C, and housed in the SMP-3 package.
For engineers reviewing the MLX90377GVE-ADB-210-TU datasheet, pinout, applications, or equivalent options, this page provides verified functional specifications, SMP-3 terminal mapping, automotive-grade safety compliance (ASIL-B), and validated alternative options for pedal, throttle, and ride height sensing designs.
Technical Context
The MLX90377GVE-ADB-210-TU integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, enabling robust absolute linear position decoding without mechanical contact. Its on-chip DSP supports programmable piecewise-linear transfer characteristics (4/8/16/32 points) and configurable filtering.
This variant implements Linear Stray-Field Immune Mode (-2xx option code), uses high-speed analog/PWM output configuration (-210), and operates in the SMP-3 PCB-less single-mold package with VDD/OUT/VSS terminals plus INPUT/TEST test pins. It achieves ASIL-B capability for analog output per ISO 26262 as a Safety Element out of Context.

Pinout & Package
SMP-3 is a PCB-less single-mold package with three main terminals (VDD, OUT, VSS) and two test pads (INPUT, TEST). It integrates decoupling capacitance internally and requires no external bypass capacitors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VDD) | Power supply input | Accepts 4.5–18 V; includes reverse polarity and overvoltage protection up to -14 V / +28 V |
| 2 (OUT) | Signal output | Push-pull analog ratiometric or PWM output; 12-bit resolution; drives 5–10 kΩ load |
| 3 (VSS) | Ground reference | Primary return path; supports broken-wire detection diagnostics when pulled down |
| a (INPUT) | Factory test interface | Not user-accessible in final application; used for wafer-level calibration and EoL testing |
| b (TEST) | Factory test interface | Not connected in operation; tied to ground per EMC recommendations if externally accessible |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Measures Bx, By, Bz simultaneously to resolve absolute linear or rotary position from magnet motion without mechanical wear |
| Programmable Transfer Curve | Supports 4-, 8-, 16-, or 32-point piecewise-linear calibration - enables precise compensation of non-ideal magnet trajectories |
| Integrated Diagnostics | Includes passive broken-wire detection on VDD/VSS and active diagnostic output - reduces need for external monitoring circuitry |
| On-Chip Decoupling | SMP-3 package embeds internal capacitors - eliminates external VDD/VDEC bypass components and saves PCB area |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GVE-ADB-310-TU | Same SMP-3 package and temperature range, but Standard/Legacy Mode with analog/PWM high-speed output - lacks Linear Stray-Field Immunity | Used where external magnetic interference is negligible, e.g., enclosed pedal modules with shielded magnets | Select when stray-field rejection is unnecessary and legacy calibration workflows apply |
| MLX90371GVE-ADB-210-TU | Previous-generation Triaxis® sensor in SMP-3; same Linear Stray-Field Immune Mode and ADB-210 output config, but 10-bit resolution and no ASIL-B certification | Deployed in cost-sensitive industrial position feedback where functional safety is not mandated | Choose for legacy design refreshes requiring footprint compatibility but lower performance and safety assurance |
Compared with MLX90377GVE-ADB-210-TU, the ADB-310 variant omits stray-field immunity and targets simpler magnetic environments, while the MLX90371GVE-ADB-210-TU retains the same package and mode but delivers lower resolution and no ISO 26262 ASIL-B qualification - making MLX90377GVE-ADB-210-TU the only option meeting full automotive safety and interference resilience requirements.

FAQ
What output protocols does the MLX90377GVE-ADB-210-TU support?
The MLX90377GVE-ADB-210-TU supports analog ratiometric and PWM outputs only. Its ADB-210 option code permanently configures it for Linear Stray-Field Immune Mode with high-speed analog/PWM operation. SENT and SPC protocols are disabled and cannot be enabled by reprogramming.
Is the MLX90377GVE-ADB-210-TU pin-compatible with other MLX90377 variants in SMP-3?
Yes, all MLX90377 variants in the SMP-3 package - including MLX90377GVE-ADB-210-TU, MLX90377GVE-ADB-310-TU, and MLX90377GVE-ADB-230-TU - share identical pinout: VDD (pin 1), OUT (pin 2), VSS (pin 3), plus INPUT (pad a) and TEST (pad b). Mechanical and electrical interface compatibility is maintained across the SMP-3 family.
Does the MLX90377GVE-ADB-210-TU require external decoupling capacitors?
No. The MLX90377GVE-ADB-210-TU in SMP-3 package integrates internal decoupling capacitance. Per datasheet section 16.4 and package specification 19.4, no external VDD bypass capacitor is needed - simplifying layout and improving reliability in space-constrained automotive modules.
What functional safety level does the MLX90377GVE-ADB-210-TU achieve?
The MLX90377GVE-ADB-210-TU is ISO 26262 ASIL-B capable for analog output mode as a Safety Element out of Context (SEooC). This certification covers fault detection, diagnostics, and fail-safe behavior - validated per Melexis safety manual and applicable to pedal, throttle, and suspension control systems.
How is stray-field immunity implemented in the MLX90377GVE-ADB-210-TU?
The MLX90377GVE-ADB-210-TU implements Linear Stray-Field Immune Mode via on-chip differential signal processing of Triaxis® Hall measurements. This mode rejects orthogonal magnetic interference up to ±1 T while preserving sensitivity to the target magnet's axial field - confirmed in datasheet section 8.2 and validated per AEC-Q200 magnetic stress testing.
