Product details
Overview
MLX90377GVS-ADB-300-RE from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC for non-contacting rotary or linear displacement measurement. It delivers 12-bit ratiometric analog and PWM outputs in Standard/Legacy Mode, operates from -40°C to 160°C, supports low-power operation, and is packaged in DMP-4 (PCB-less dual mold) with tape-and-reel delivery (2500 pcs/reel).
For engineers reviewing the MLX90377GVS-ADB-300-RE datasheet, pinout, applications, or equivalent options, key selection criteria include its DMP-4 package compatibility with prior Triaxis® generations, programmable transfer characteristic, stray-field robustness in Standard Mode, and ASIL-B functional safety compliance for analog output.
Technical Context
The MLX90377GVS-ADB-300-RE integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, a 12-bit ADC, DSP-based signal processing engine, and dual-output stage supporting ratiometric analog and PWM. Its architecture enables absolute angular (0–360°) or linear position decoding using external magnet configurations without mechanical contact.
This variant implements Standard/Legacy Mode with Analog/PWM output and Low Power Mode firmware configuration. It uses the DMP-4 package (4-pin, PCB-less), features built-in decoupling capacitors, and complies with ISO 26262 ASIL-B for analog output mode as a Safety Element out of Context.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Modes | Ratiometric analog (0.5–4.5 V) and PWM (duty cycle proportional to position); not SENT/SPC - fixed by ADB-300 option code. |
| Resolution | 12-bit effective resolution for both analog and PWM outputs, enabling ≤0.1° angular or sub-millimeter linear position discrimination. |
| Operating Temp | -40°C to +160°C ambient range - validated for under-hood automotive environments and industrial motor feedback. |
| Supply Voltage | 4.5–5.5 V (regulated) or 6–18 V (battery-powered, PWM-only); reverse voltage protection to -14 V for 48 h. |
| Supply Current | 8–11.5 mA typical in Legacy Mode (-30x code), optimized for low-power continuous sensing in battery-backed systems. |
| Magnetic Sensitivity | Supports ±1 T maximum flux density; Standard Mode provides robustness against stray fields without requiring high-field magnets. |
| Safety Certification | ISO 26262 ASIL-B capable for analog output mode - enables use in safety-critical subsystems without full ASIL-C hardware redundancy. |
Pinout & Package
DMP-4 package: PCB-less dual-mold construction with integrated decoupling capacitors, 4-pin straight-lead configuration (STD2 2.54 mm pitch), RoHS-compliant, designed for direct soldering onto flex or rigid PCBs without carrier substrate.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog and digital domains; must be connected to system ground with low-impedance path. |
| 2 | VDD | Main supply input (4.5–18 V); internal regulator powers core logic and Hall front end; reverse polarity protected. |
| 3 | OUT | Push-pull output terminal delivering either ratiometric analog voltage (0.5–4.5 V) or PWM signal (0–100% duty cycle). |
| 4 | VSS | Dedicated ground return for output driver; improves EMC performance and reduces ground bounce during PWM switching. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous measurement of Bx, By, Bz enables true 3D magnetic field decoding - eliminates need for precise magnet alignment in rotary/linear applications. |
| Programmable Transfer Characteristic | Configurable 4- or 8-point piecewise-linear mapping allows custom calibration to mechanical travel limits without external lookup tables. |
| DMP-4 Integrated Decoupling | Built-in capacitors eliminate external bulk capacitance - reduces BOM count and PCB footprint while maintaining stable regulation under load transients. |
| Stray-Field Immunity (Standard Mode) | Robust operation in magnetically noisy environments (e.g., near motors or solenoids) without shielding or recalibration - verified per IEC 61000-4-8. |
| Low-Power Firmware Mode | Optimized internal clock gating and reduced sampling rate cut current draw to ≤8 mA - extends battery life in portable or energy-harvested sensors. |
Applications

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 package (8-pin, surface-mount) instead of DMP-4; requires external decoupling capacitors and larger PCB area. | Better suited for prototyping or legacy board reuse where SOIC-8 footprint exists; lacks DMP-4's integrated capacitors and compact form factor. | Select when board layout already accommodates SOIC-8 or when higher thermal mass is needed for sustained 160°C operation. |
| MLX90377GVS-ADB-310-RE | Same DMP-4 package but configured for High Speed Mode - increases sampling rate and reduces latency at cost of +2.5 mA supply current. | Required for closed-loop control loops demanding <50 µs response (e.g., active suspension), not needed for static or slow-varying position monitoring. | Choose only if application requires faster update rate; otherwise MLX90377GVS-ADB-300-RE delivers optimal power/performance balance. |
Compared with MLX90377GVS-ADB-300-RE, the SOIC-8 variant offers greater layout flexibility but adds BOM cost and board space, while the ADB-310 variant trades power efficiency for speed - making MLX90377GVS-ADB-300-RE the preferred choice for cost-sensitive, thermally constrained, or battery-operated absolute position sensing.

FAQ
What output protocols does MLX90377GVS-ADB-300-RE support?
The MLX90377GVS-ADB-300-RE is factory-configured for Standard/Legacy Mode with ratiometric analog and PWM outputs only. SENT and SPC protocols are not enabled - they require different option codes (e.g., ADB-330 or ADB-380) and cannot be reprogrammed in the field. This ensures deterministic behavior in safety-critical analog feedback loops.
Is MLX90377GVS-ADB-300-RE pin-compatible with earlier Triaxis® sensors in DMP-4 package?
Yes, MLX90377GVS-ADB-300-RE maintains pin-to-pin compatibility with prior-generation Triaxis® devices in DMP-4 packaging, including identical 4-pin layout (VSS-VDD-OUT-VSS), mechanical dimensions, and solder profile. This enables drop-in replacement without PCB redesign or requalification.
What is the operating temperature range of MLX90377GVS-ADB-300-RE and how is it validated?
MLX90377GVS-ADB-300-RE is rated for -40°C to +160°C ambient operation and qualified per AEC-Q100 Grade 0. Electrical specifications, startup time, and output accuracy are guaranteed across this full range, with thermal drift compensated in firmware and validated through accelerated life testing at 175°C junction temperature.
Does MLX90377GVS-ADB-300-RE include built-in protection features?
Yes, MLX90377GVS-ADB-300-RE integrates reverse voltage protection (-14 V for 48 h), overvoltage clamp (37 V max), broken-wire detection on VDD and VSS, and short-circuit tolerant output drivers. These features eliminate need for external protection circuitry in automotive 12 V/24 V systems.
How is functional safety implemented in MLX90377GVS-ADB-300-RE?
MLX90377GVS-ADB-300-RE achieves ISO 26262 ASIL-B capability for analog output mode as a Safety Element out of Context. It includes internal diagnostics (watchdog, memory ECC, signal path checks), fail-safe high-impedance output state, and documented fault handling time intervals - all covered in Melexis' certified safety manual.
