Product details
Overview
MLX90422GVD-ADD-030-RE from Melexis is a Triaxis® monolithic magnetic position sensor IC for absolute rotary position sensing, featuring SENT output per SAE J2716 APR2016, ISO26262 ASIL B safety element out of context, AEC-Q100 Grade 0 qualification, and operation from −40°C to +160°C ambient.
For engineers reviewing the MLX90422GVD-ADD-030-RE datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (SMP-4), confirmed dual-die SENT timing (Tframe = 861–905 μs), functional safety architecture, and real-world automotive use cases including throttle and steering wheel position sensing.
Technical Context
The MLX90422GVD-ADD-030-RE implements Triaxis® Hall sensing with on-chip DSP-based linearization using up to 17 programmable transfer points, enabling robust absolute angle calculation from Bx, By, and Bz field components. Its dual-die SMP-4 package provides hardware redundancy with isolated ground paths (Risol ≥ 4 MΩ) and independent SENT outputs (OUT1/OUT2).
It operates in continuous synchronous acquisition mode by default, delivering two angle acquisitions per SENT frame with fixed 3 μs tick time, A.3 (H.4) format, and deterministic latency (1.32–2.03 ms). Diagnostic cycles include analog (10.4 ms) and digital (19.7 ms) intervals, supporting fault detection per ISO26262 ASIL B requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Protocol | SENT per SAE J2716 APR2016, A.3 (H.4) format with pause pulse - enables high-resolution, noise-immune digital transmission to ECU. |
| Operating Temp | −40°C to +160°C ambient - qualified for under-hood automotive environments without derating. |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5 V automotive power rails; supports overvoltage detection up to 6.25 V. |
| Supply Current | 15–20 mA total (dual die) - enables low-power system design while maintaining full redundancy. |
| Angle Accuracy | ±0.5° typical INL - achieved via on-chip 16-point DSP linearization and Triaxis® 3-axis field vector resolution. |
| Startup Time | Tstup = 5.93 ms - time to first valid angle output after power-on, critical for engine start sequence timing. |
| Frame Period | 861–905 μs - deterministic SENT frame length ensures predictable ECU sampling synchronization. |
Pinout & Package
SMP-4 is a PCB-less single-mold dual-die package with 4 terminals, optimized for compact, high-reliability automotive position sensing. It integrates decoupling capacitance and supports direct soldering onto flex or rigid substrates.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Digital SENT output from die 1 - provides independent channel for redundancy validation or dual-signal processing. |
| 2 | VSS | Common ground reference for both dies - internally isolated between dies; requires external low-impedance connection. |
| 3 | VDD | Single 5 V supply input for both dies - shared rail simplifies power delivery while maintaining functional isolation. |
| 4 | OUT2 | Digital SENT output from die 2 - enables cross-checking, fail-safe comparison, or dual-channel ECU interface. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3-Axis Sensing | Simultaneous Bx, By, Bz measurement enables absolute angular position calculation without mechanical stops or multi-turn gearing. |
| Programmable Transfer Curve | Up to 17-point user-defined linearization allows precise calibration to magnet geometry and air gap variations in production. |
| ISO26262 ASIL B SEooC | Delivers documented safety mechanisms (CRC, watchdogs, diagnostics) without requiring additional system-level safety hardware. |
| Dual-Die Redundancy (SMP-4) | Independent signal chains with isolated grounds support fault-tolerant architectures meeting ASIL D decomposition requirements. |
| SENT with Pause Pulse | Fixed-frame protocol ensures deterministic timing for ECU synchronization and eliminates jitter-induced sampling errors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90422GDC-ADD-030-RE | SOIC-8 single-die package; no hardware redundancy; 8-pin footprint; higher thermal resistance (θJA = 120°C/W). | Targeted at cost-sensitive non-redundant applications (e.g., HVAC dampers, industrial levers) where ASIL B decomposition is not required. | Select when board space permits SOIC-8 and dual-die redundancy is unnecessary; verify EMC compliance with external decoupling. |
| MLX90422GGO-ADD-030-RE | TSSOP-16 dual-die package with full pin separation (VDD1/VSS1/VDD2/VSS2); 16-pin layout; isolation resistance ≥4 MΩ between dice. | Used where PCB-level isolation and separate power domains are mandated (e.g., high-integrity chassis control modules). | Choose when discrete die supply/ground routing is required; note larger footprint and higher assembly complexity than SMP-4. |
Compared with MLX90422GDC-ADD-030-RE and MLX90422GGO-ADD-030-RE, the MLX90422GVD-ADD-030-RE offers identical core sensing and SENT functionality but integrates dual-die redundancy into a compact 4-terminal SMP-4 package-reducing PCB area by 65% versus TSSOP-16 and eliminating external isolation components required in SOIC-8 designs.
