Product details
Overview
MLX90422GVD-ADD-030-RX 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, SENT (SAE J2716 APR2016) output, and operates from -40°C to +160°C with AEC-Q100 Grade 0 qualification. It delivers 12-bit angular resolution, ±0.5° total accuracy over temperature, and supports programmable linearization up to 17 points - used in automotive throttle and pedal position sensing.
For engineers reviewing the MLX90422GVD-ADD-030-RX datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SMP-4 package pin mapping, SENT timing compliance, ISO26262 ASIL B safety architecture, and real-world automotive positioning use cases.
Technical Context
The MLX90422GVD-ADD-030-RX implements Triaxis® technology to measure Bx, By, and Bz magnetic field components simultaneously, enabling robust absolute angle calculation without mechanical contact. Its on-chip DSP performs real-time linearization using up to 17 user-defined transfer points and supports dual-die redundancy via independent SENT outputs (OUT1/OUT2).
This variant uses the SMP-4 package - a PCB-less single-mold dual-die configuration - delivering functional safety through hardware-level die isolation (Risol ≥ 4 MΩ), independent supply/ground paths per die, and synchronized SENT frame transmission compliant with SAE J2716 A.1 (Dual Throttle Position Sensor) format.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Protocol | SENT (SAE J2716 APR2016), A.1 Dual Throttle Position Sensor format with CRC and diagnostics |
| Angular Resolution | 12-bit (4096 steps), enabling 0.088° step size over 360° full-scale rotation |
| Total Accuracy | ±0.5° over -40°C to +160°C, including INL, DNL, thermal drift, and magnetic hysteresis |
| Supply Range | 4.5 V to 5.5 V; supports extended operation up to 180°C ambient for SMP-4 package |
| Startup Time | Tstup = 5.93 ms (typical) to first valid angle output in synchronous SENT mode |
| Latency | 1.32–2.03 ms (typ–max), dependent on filter configuration and clock drift |
| Operating Temp | -40°C to +160°C continuous; +180°C for ≤250 h with performance derating |
Pinout & Package
SMP-4 is a PCB-less single-mold dual-die package with 4 terminals: two outputs (OUT1/OUT2), one shared supply (VDD), and one shared ground (VSS). It enables compact, high-reliability mounting directly onto flexible substrates or leadframes without PCB routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Digital SENT output from die 1; carries primary angle data and diagnostics in A.1 format |
| 2 | VSS | Common ground reference for both dies; must be low-impedance for EMC and diagnostic integrity |
| 3 | VDD | Shared 4.5–5.5 V supply input; powers both dies independently via internal regulation |
| 4 | OUT2 | Digital SENT output from die 2; carries redundant angle data and independent diagnostics |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3-Axis Sensing | Simultaneous Bx/By/Bz measurement enables true 3D magnetic field vector resolution for absolute angle calculation |
| Dual-Die Redundancy | Independent die-level power, ground, and SENT outputs support ASIL B decomposition per ISO26262 |
| Programmable Linearization | Up to 17-point user-defined transfer curve compensates for magnet nonlinearity and mechanical eccentricity |
| SENT Diagnostics | Embedded CRC, broken-wire detection (92.5–99.5% VDD level reporting), and configurable fault flags per output |
| High-Temp Operation | Validated operation at +180°C ambient for ≤250 h with defined derating - critical for under-hood applications |
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 |
|---|---|---|---|
| MLX90422GVS-ADD-030-RX | DMP-4 package (single-die, 4-pin), no redundancy, lower cost, same SENT A.1 protocol and accuracy | Lacks dual-die isolation and independent diagnostics; suitable for ASIL A or non-safety-critical linear/rotary sensing | Select when redundancy and ASIL B decomposition are not required; saves board space vs SOIC-8 but lacks die-level fault separation |
| MLX90422GGO-ADD-030-RE | TSSOP-16 package (dual-die, 16-pin), includes dedicated VDD/VSS per die and higher pin count for test access | Requires PCB routing and larger footprint; offers enhanced EMC shielding and factory testability vs SMP-4 | Choose when board-level test access, thermal margin beyond 180°C, or legacy TSSOP compatibility is prioritized over miniaturization |
Compared with MLX90422GVD-ADD-030-RX, the DMP-4 variant reduces cost and size but removes die-level redundancy, while the TSSOP-16 version adds test flexibility and thermal headroom at the expense of footprint and assembly complexity.
