Product details
Overview
MLX90422GVD-ADD-030-SP from Melexis is a Triaxis® monolithic magnetic position sensor IC for absolute rotary position sensing. It integrates a 3-axis Hall front end, DSP-based signal conditioning, programmable linearization (up to 17 points), SENT output per SAE J2716 APR2016, and operates from −40°C to +160°C in SMP-4 package. It delivers robust non-contacting angular measurement in automotive throttle and steering systems.
For engineers reviewing the MLX90422GVD-ADD-030-SP datasheet, pinout, applications, or equivalent options, this page provides verified functional context, SMP-4 terminal mapping, SENT timing compliance, ASIL B safety status, and AEC-Q100 Grade 0 qualification - all confirmed against Revision 004 (March 2026) official documentation.
Technical Context
The MLX90422GVD-ADD-030-SP implements dual-die redundancy in a single-mold SMP-4 package with two independent SENT outputs (OUT1 and OUT2), isolated supply/ground paths per die, and internal decoupling. Its Triaxis® architecture measures Bx, By, and Bz components simultaneously, enabling configurable axis selection (e.g., X-Z or Y-Z) for absolute angle calculation from magnet rotation.
It supports both synchronous (fixed-frame SENT with pause pulse, 287-tick frame, 861–905 µs refresh) and asynchronous (variable-frame SENT without pause, 512–537 µs internal acquisition period) modes. Programmable diagnostics include broken-wire detection on VDD/VSS with 92.5–99.5% VDD passive output levels and configurable field thresholds (BTH_LOW = 2–30 mT, BTH_HIGH = 70–126 mT).
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
SMP-4 is a PCB-less single-mold dual-die package measuring 2.9 mm × 2.8 mm × 0.9 mm (L×W×H), RoHS-compliant, with integrated capacitors and no external decoupling required. It enables compact, high-reliability placement directly on flex or rigid PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Dedicated SENT output for die 1; electrically isolated from OUT2, enabling dual-channel fault-tolerant reporting |
| 2 | VSS | Common ground terminal shared by both dies; requires low-impedance connection to system GND |
| 3 | VDD | Single supply input (4.5–5.5 V) powering both dies; internal regulators derive VDEC for analog blocks |
| 4 | OUT2 | Dedicated SENT output for die 2; supports independent frame transmission or synchronized dual-output mode |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3-Axis Sensing | Simultaneous Bx, By, Bz measurement enables flexible magnet geometry (axial/radial) and eliminates mechanical alignment sensitivity |
| Dual-Die Redundancy (SMP-4) | Two independent sensor dies in one package with isolated power/ground paths and separate SENT outputs for ASIL B compliance |
| Programmable Linearization | Up to 17-point user-defined transfer curve compensates for magnet nonlinearity and mechanical tolerances in production |
| SENT Diagnostics | Embedded broken-wire detection (VDD/VSS open), field-too-low/high alerts, and CRC-protected frames reduce ECU software overhead |
| High-Temperature Operation | Validated operation at +180°C ambient for ≤250 h in SMP-4 package, supporting under-hood and transmission applications |

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 |
|---|---|---|---|
| MLX90421GVD-ADD-030-SP | Single-die SMP-4 variant; identical pinout and SENT protocol but no dual-output redundancy | Lacks ASIL B-ready dual-die isolation; suitable for non-safety-critical linear/rotary sensing | Select when cost-sensitive designs do not require fault-tolerant dual-channel reporting |
| MLX90422GGO-ADD-030-SP | TSSOP-16 package with full die-level isolation (Risol ≥4 MΩ), larger footprint (5×4.4 mm), and 16-pin routing | Better EMC margin and thermal dissipation than SMP-4; requires PCB space and layout complexity | Choose when board-level isolation verification or higher power dissipation (>20 mA) is needed |
Compared with MLX90422GVD-ADD-030-SP, the MLX90421GVD-ADD-030-SP reduces cost and size but removes functional safety capability, while the MLX90422GGO-ADD-030-SP trades compactness for enhanced isolation and thermal headroom - making the SMP-4 dual-die version optimal for space-constrained ASIL B systems.
