Product details
Overview
MLX90377GVS-ADB-333-RX from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC in DMP-4 package, delivering 12-bit SENT output with 3 μs tick time, operating from -40°C to 160°C, and certified ASIL-C capable for SENT mode - used in automotive throttle and pedal position sensing where stray-field immunity and functional safety are critical.
For engineers reviewing the MLX90377GVS-ADB-333-RX datasheet, pinout, applications, or equivalent options, this page provides verified pin definitions, SENT protocol timing, DMP-4 mechanical interface, ASIL-C safety architecture, and validated alternatives for rotary/linear position sensing in harsh environments.
Technical Context
The MLX90377GVS-ADB-333-RX integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, enabling absolute angular (0–360°) or linear position decoding without contact. Its on-chip DSP supports programmable piecewise-linear transfer characteristics (up to 32 segments) and configurable filtering for noise rejection in high-EMI environments.
This variant operates in Standard/Legacy Mode with SENT v4.0 (SAE J2716 APR2016), delivers 12-bit resolution with CRC-protected frames, and uses internal voltage regulation with reverse-polarity and overvoltage protection - all implemented in a PCB-less dual-mold DMP-4 package optimized for compact, high-reliability mounting on flex or rigid substrates.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Protocol | SENT v4.0 (SAE J2716 APR2016), 12-bit resolution, 3 μs tick time - enables deterministic, error-coded digital transmission compatible with automotive ECUs. |
| Operating Temp | -40°C to +160°C - qualified for under-hood and transmission-mounted applications without external thermal derating. |
| Supply Voltage | 4.5 V to 5.5 V (regulated) or 6 V to 18 V (battery) - supports direct connection to vehicle battery with integrated protection. |
| Functional Safety | ISO 26262 ASIL-C capable for SENT output - certified Safety Element out of Context (SEooC) with diagnostic coverage for fault detection and reporting. |
| Magnetic Sensing | Triaxis® 3D Hall front end - measures Bx, By, Bz simultaneously to resolve absolute position from magnet motion without mechanical coupling. |
| Package | DMP-4 (PCB-less dual mold) - 4-pin surface-mount package with straight leads, footprint-compatible with legacy Triaxis® sensors and optimized for automated assembly. |
| Accuracy | ±0.3° typical angular accuracy (Standard/Legacy Mode) - achieved via on-chip DSP compensation for temperature, nonlinearity, and magnetic hysteresis. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90371GVS-ADB-333-RX | Legacy Triaxis® generation; same DMP-4 package and SENT-3μs output, but lacks ASIL-C certification and advanced DSP filtering. | Suitable for non-safety-critical industrial position sensing; not approved for ASIL-B/C automotive subsystems. | Select when cost sensitivity outweighs functional safety requirements and legacy calibration tools are in use. |
| TLV320ADC3101IRHBT | Audio ADC with I²C interface - no magnetic sensing, no Triaxis® architecture, no SENT output, and no automotive temperature rating. | Not functionally equivalent; serves audio signal chain, not position feedback. | Exclude - misaligned function, interface, and qualification; not a valid alternative for MLX90377GVS-ADB-333-RX use cases. |
Compared with MLX90377GVS-ADB-333-RX, MLX90371GVS-ADB-333-RX offers identical mechanical fit and basic SENT output but omits ASIL-C mechanisms and advanced diagnostics; the TLV320ADC3101IRHBT is unrelated and unsuitable for position sensing.
