Product details
Overview
MLX90377GVE-ADB-310-RX from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC for rotary or linear non-contact sensing. It delivers 12-bit resolution analog and PWM outputs in High Speed Mode, operates from -40°C to 160°C, supports stray-field immune configurations, and is packaged in SMP-3 (PCB-less single mold). It serves as the core magnetic position transducer in automotive throttle and pedal position systems.
For engineers reviewing the MLX90377GVE-ADB-310-RX datasheet, pinout, applications, or equivalent options, key selection criteria include its SMP-3 package footprint, High Speed Mode timing (≤100 µs latency), ratiometric analog/PWM dual-output capability, ASIL-B functional safety compliance, and programmable transfer characteristic with up to 32-piecewise-linear points.
Technical Context
The MLX90377GVE-ADB-310-RX integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, a 12-bit ADC, DSP-based signal conditioning, and firmware-configurable output drivers. Its SMP-3 package contains built-in decoupling capacitors and uses a 3-pin layout optimized for compact, high-reliability mounting in constrained spaces.
This variant implements Standard/Legacy Mode with Analog/PWM output in High Speed Mode (Option Code ADB-310), enabling ≤100 µs latency and 12-bit resolution. It is certified ASIL-B capable for analog output and ASIL-C capable for SENT/PWM/SPC modes per ISO 26262, with diagnostics including broken-wire detection on VDD and VSS.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Resolution | 12-bit (4096 steps) for both analog and PWM outputs |
| Operating Temp | -40°C to +160°C - qualified for under-hood automotive environments |
| Supply Voltage | 4.5 V to 5.5 V (regulated) or 6 V to 18 V (battery mode, PWM only) |
| Latency | ≤100 µs typical in High Speed Mode - enables real-time closed-loop control |
| Stray-Field Immunity | Standard/Legacy Mode (ADB-3xx) - optimized for general-purpose angular/linear sensing without enhanced immunity |

Pinout & Package
SMP-3 is a PCB-less single-mold package with integrated decoupling capacitors, designed for direct soldering onto flex or rigid substrates. Its 3-pin configuration minimizes board space and simplifies assembly in tight mechanical envelopes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VDD) | Supply input | Accepts 4.5–18 V; internal regulator powers analog/digital blocks; requires external bulk capacitance if not using built-in caps |
| 2 (OUT) | Programmable output | Drives ratiometric analog voltage (0.5–4.5 V) or PWM signal (0–100% duty cycle); push-pull or open-drain configurable |
| 3 (VSS) | Ground reference | Primary return path; used for broken-wire detection (BVSSPD/BVSSPU diagnostics) |
| a (INPUT) | Test input | Factory test interface; not intended for end-user connection; tie to VSS for EMC |
| b (TEST) | Test control | Internal test access; must be connected to VSS in application; no user functionality |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous measurement of Bx, By, Bz enables absolute angle/position decoding without external concentrators |
| Programmable Transfer Characteristic | Up to 32-point piecewise-linear calibration allows precise linearization across custom mechanical ranges |
| Integrated Decoupling | SMP-3 package includes built-in capacitors - eliminates need for external VDD/VSS bypass caps in most layouts |
| Broken-Wire Diagnostics | Detects open-circuit faults on VDD and VSS lines via passive diagnostic output levels (BVDDPU/BVSSPD) |
| Ratiometric Output Stability | Analog output tracks VDD variation (±0.1%/V), ensuring accuracy across battery voltage fluctuations |

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-310-RE | SOIC-8 package (8-pin, surface-mount), no built-in capacitors, requires external decoupling | Better suited for prototyping or PCB-based designs where manual capacitor placement is acceptable | Select when board space permits larger footprint and design flexibility for external filtering is preferred |
| MLX90377GVE-ADB-300-RX | Same SMP-3 package but Low Power Mode - higher latency (~500 µs), lower supply current (8–9 mA) | Optimized for energy-constrained systems like battery-powered sensors or sleep-mode wake-up applications | Choose when power efficiency outweighs real-time response requirements |
Compared with MLX90377GVE-ADB-310-RX, the SOIC-8 variant offers greater layout flexibility but increases component count and board area, while the ADB-300-RX reduces power consumption at the cost of latency - making MLX90377GVE-ADB-310-RX optimal for high-dynamics, space-constrained automotive actuation feedback.

FAQ
What output protocols does the MLX90377GVE-ADB-310-RX support?
The MLX90377GVE-ADB-310-RX supports analog ratiometric voltage and PWM outputs exclusively in High Speed Mode, as defined by its ADB-310 option code. It does not support SENT or SPC protocols - those require different option codes (e.g., ADB-330 or ADB-380). The output mode is factory-programmed and cannot be changed in the field.
Is the MLX90377GVE-ADB-310-RX pin-compatible with earlier Triaxis® sensors?
Yes - the MLX90377GVE-ADB-310-RX in SMP-3 package maintains pin-to-pin compatibility with prior-generation Triaxis® sensors using the same 3-pin layout (VDD, OUT, VSS). This enables drop-in replacement in legacy designs without PCB revision, provided mechanical mounting and thermal constraints remain compatible.
Does the MLX90377GVE-ADB-310-RX require external decoupling capacitors?
No - the SMP-3 package of the MLX90377GVE-ADB-310-RX integrates decoupling capacitors internally. External capacitors are not required for standard operation, though a 100 nF ceramic capacitor may be added near the VDD pin for enhanced high-frequency noise suppression in electrically noisy environments.
What is the functional safety status of the MLX90377GVE-ADB-310-RX in analog output mode?
The MLX90377GVE-ADB-310-RX is ISO 26262 ASIL-B capable in analog output mode, classified as a Safety Element out of Context (SEooC). It includes diagnostics such as broken-wire detection on VDD and VSS, internal voltage monitoring, and startup validation - all documented in the official safety manual for integration into ASIL-B systems.
Can the transfer characteristic of the MLX90377GVE-ADB-310-RX be customized after purchase?
Yes - the MLX90377GVE-ADB-310-RX supports end-user programming of its transfer characteristic via Melexis' PTC (Programming through Connector) interface. Users can configure up to 32-piecewise-linear points, select between 4/8/16/32 segments, and adjust offset/gain - all stored in on-chip NVRAM without requiring special programming hardware beyond a standard UART connection.
