Product details
Overview
MLX90422GVS-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, and SENT (SAE J2716 APR2016) output. Operating from −40°C to +160°C with ±10 mT useful magnetic flux density norm, it delivers 0–360° angular position in automotive pedal and throttle systems.
For engineers reviewing the MLX90422GVS-ADD-030-RX datasheet, pinout, applications, or equivalent options, key selection factors include its DMP-4 package footprint, SENT A.3 (H.4) frame format, programmable 17-point linearization, ISO26262 ASIL B safety element out of context compliance, and dual-mold PCB-less construction optimized for high-temperature under-hood placement.
Technical Context
The MLX90422GVS-ADD-030-RX uses Triaxis® Hall technology to measure Bx, By, and Bz components simultaneously, enabling robust absolute angle calculation via on-chip DSP. Its magnetic sensing mode is configurable for X-Y, X-Z, or Y-Z plane operation, with IMC gain fixed at 1.19.
It operates in continuous synchronous SENT mode by default: 3 μs tick time, 287-tick frames (861–905 μs), dual angle acquisitions per frame, and 16-point DSP linearization. Startup time to first valid angle is 5.93 ms, with average latency of 1.32–2.03 ms depending on filter configuration.

Pinout & Package
DMP-4 (Dual Mold Package) is a compact, PCB-less, surface-mount package with 4 terminals and RoHS-compliant molding. Designed for direct magnet coupling and high-temperature resilience, it eliminates external decoupling capacitors via integrated capacitance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog/digital circuitry; must be connected to system ground |
| 2 | VDD | Primary supply input (4.5–5.5 V); powers internal regulator and sensor core |
| 3 | OUT | Open-drain SENT output; requires external pull-up to Vext (VDD) |
| 4 | VSS | Second ground terminal; improves EMC and thermal dissipation in DMP-4 layout |
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 air-gap variation in production calibration |
| SENT A.3 (H.4) Output | Standardized SAE J2716-compliant serial interface with CRC, diagnostics, and error codes-directly compatible with automotive ECU receivers |
| On-Chip Diagnostics | Integrated analog and digital diagnostic cycles (10.4 ms / 19.7 ms) detect broken-wire, overvoltage, undervoltage, and magnetic field faults |
| Dual-Mold Construction | DMP-4 package embeds sensor die and passive components in single mold, eliminating PCB assembly and enhancing thermal reliability up to +180°C |

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 |
|---|---|---|---|
| MLX90421GVS-ADD-030-RX | Single-die variant with identical DMP-4 package, SENT A.3 output, and 16-point linearization-but lacks dual-die redundancy and ASIL B certification | Targeted at cost-sensitive industrial or non-safety-critical automotive subsystems | Select when ASIL B compliance and functional safety documentation are not required |
| AMS AS5600-WSCT | 12-bit I²C output, no SENT support; lower temperature rating (−40°C to +125°C); no ASIL qualification or AEC-Q100 Grade 0 | Suitable for consumer electronics or light industrial encoders-not for automotive powertrain or chassis control | Choose only for non-automotive designs where SENT interface and high-temp operation are unnecessary |
Compared with MLX90422GVS-ADD-030-RX, the MLX90421GVS-ADD-030-RX offers identical packaging and basic functionality but omits safety certification and redundancy, while the AMS AS5600-WSCT trades automotive robustness and SENT compatibility for simpler I²C integration and lower cost in non-safety contexts.

FAQ
What is the package type and mounting configuration of the MLX90422GVS-ADD-030-RX?
The MLX90422GVS-ADD-030-RX uses the DMP-4 (Dual Mold Package), a PCB-less, surface-mount 4-terminal package with two ground pins (VSS), one supply (VDD), and one open-drain SENT output (OUT). It is designed for direct soldering onto host boards with no external decoupling capacitors required due to integrated capacitance.
Does the MLX90422GVS-ADD-030-RX support SENT protocol versions other than A.3 (H.4)?
No-the MLX90422GVS-ADD-030-RX is factory-configured for SENT Single Secure Sensor A.3 (H.4) format with pause pulse. While the device supports programmable SENT modes via NVRAM, the ADD-030 option code specifically locks it to A.3 (H.4); alternative formats like A.1 (H.1) require different option codes (e.g., ADD-031) and are not supported by this exact part number.
What is the maximum allowable ambient temperature for continuous operation of the MLX90422GVS-ADD-030-RX?
The MLX90422GVS-ADD-030-RX is rated for continuous operation from −40°C to +160°C. It also supports extended high-temperature exposure up to +180°C for ≤250 hours in DMP-4 packages, with degraded performance per Table 10 in the datasheet-valid only for ambient conditions, not junction temperature.
How does the MLX90422GVS-ADD-030-RX achieve ASIL B compliance without hardware redundancy?
The MLX90422GVS-ADD-030-RX achieves ISO26262 ASIL B as a Safety Element out of Context (SEooC) through comprehensive on-chip diagnostics-including analog/digital watchdogs, supply monitoring, magnetic field sanity checks, and SENT CRC validation-documented in Melexis' functional safety manual. Its DMP-4 package contains a single die; redundancy is not required for ASIL B when diagnostic coverage and fault response meet standard requirements.
Can the MLX90422GVS-ADD-030-RX be reprogrammed in-system for different linearization curves or SENT configurations?
Yes-the MLX90422GVS-ADD-030-RX supports in-system programming of its NVRAM via SENT interface using Melexis' PTM (Programmer Tool Manager) software. Users can update the 17-point linearization table, SENT frame structure, diagnostic thresholds, and magnetic sensing mode-though the base protocol (A.3 H.4) and package configuration remain fixed per the ADD-030 option code.
