Product details
Overview
MLX90422GVS-ADD-033-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, programmable linear transfer characteristic (up to 17 points), SENT output per SAE J2716 APR2016, and operates from −40°C to +160°C in DMP-4 package. It delivers robust non-contacting angular measurement in automotive throttle and pedal position systems.
For engineers reviewing the MLX90422GVS-ADD-033-RX datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SENT timing values, magnetic field thresholds, ASIL B safety status, and DMP-4 package-specific pin definitions - all confirmed from Melexis Revision 004 (March 2026) documentation.
Technical Context
The MLX90422GVS-ADD-033-RX uses Triaxis® Hall technology to measure Bx, By, and Bz components simultaneously, enabling absolute angle calculation via on-chip DSP. Its SENT output supports A.3 (H.4) format with fixed 3 µs tick time, 287-tick frame length, and dual-angle acquisition per frame in synchronous mode.
It features programmable diagnostics including field-too-low (2–30 mT) and field-too-high (70–126 mT) thresholds, configurable linearization (17-point), and internal analog voltage regulation at 3.3 V ±0.1 V. The device meets ISO 26262 ASIL B as a Safety Element out of Context and is AEC-Q100 Grade 0 qualified.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for both analog and digital domains; must be connected to low-impedance system ground |
| 2 | VDD | Primary supply input (4.5–5.5 V); powers internal regulator generating 3.3 V analog rail |
| 3 | OUT | Open-drain SENT output; requires external pull-up to Vext (≤VDD); compliant with SAE J2716 voltage levels |
| 4 | VSS | Second ground terminal; improves EMC performance and current return path separation |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3-Axis Sensing | Simultaneous Bx, By, Bz measurement enables true 3D magnetic field analysis for absolute angle derivation without mechanical stops |
| Programmable Linearization | Up to 17-point user-defined transfer curve compensates for magnet nonlinearity and mechanical eccentricity in rotary assemblies |
| SENT Output with Diagnostics | Embedded CRC, error codes, and passive diagnostics (broken-wire detection at 99.5% VDD) support functional safety monitoring |
| Dual-Die Redundancy Option | While MLX90422GVS-ADD-033-RX is single-die DMP-4, the same family offers TSSOP-16 and SMP-4 dual-die variants for ASIL D system-level redundancy |
| High-Temp Operation | Validated operation at +180°C ambient for ≤250 h enables use in engine bay and transmission proximity applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute rotary position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90422GVS-ADD-030-RX | Same DMP-4 package and SENT interface, but uses standard straight leads (STD0) instead of STD2 bent leads; identical electrical and magnetic specs. | Requires different PCB footprint and pick-and-place tooling due to lead geometry; not mechanically interchangeable. | Select ADD-030-RX for horizontal mounting or legacy board compatibility; ADD-033-RX for vertical mounting with space-constrained headers. |
| MLX90422GDC-ADD-033-RE | SOIC-8 package variant with same ADD-033 option code; includes two N.C. pins and separate VDEC decoupling pin; higher pin count and larger footprint. | Designed for prototyping and applications requiring external capacitor flexibility; lacks integrated decoupling of DMP-4. | Choose SOIC-8 version when design requires test access (Test1/Test2 pins) or discrete decoupling control; DMP-4 preferred for production cost and size. |
Compared with MLX90422GVS-ADD-033-RX, the ADD-030-RX differs only in lead form (straight vs. bent), while the SOIC-8 variant trades compactness for debuggability and external filtering options - making DMP-4 optimal for volume automotive modules where size, reliability, and integrated capacitance matter most.
