Product details
Overview
MLX90422GVD-ADD-030-TU from Melexis is a Triaxis® Hall-based monolithic magnetic position sensor IC for absolute rotary position sensing. It delivers SENT output per SAE J2716 APR2016 (A.3/H.4 format), supports programmable 17-point linearization, operates from −40°C to +160°C, and uses SMP-4 dual-die PCB-less packaging for redundancy in automotive throttle and steering applications.
For engineers reviewing the MLX90422GVD-ADD-030-TU datasheet, pinout, applications, or equivalent options, this page provides verified functional context, SMP-4 package terminal mapping, SENT timing compliance, ASIL B safety integration, and direct alternatives for redundant angular sensing designs.
Technical Context
The MLX90422GVD-ADD-030-TU integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, an analog-to-digital signal conditioner, and a DSP performing real-time angle calculation with up to 17-point user-programmable linearization. Its dual-die architecture in the SMP-4 package enables fault-tolerant operation via independent die outputs (OUT1/OUT2).
It implements SENT communication with fixed 3 μs tick time, supports both synchronous (pause pulse) and asynchronous (no pause) frame modes, and includes programmable diagnostics such as field-too-low/high thresholds (BTH_LOW = 2–30 mT, BTH_HIGH = 70–126 mT) and dual-die isolation monitoring.
Key Specifications

Pinout & Package
SMP-4 is a PCB-less single-mold dual-die package with 4 terminals: two dedicated outputs (OUT1/OUT2), one shared supply (VDD), and one shared ground (VSS). Designed for high-reliability automotive mounting with integrated decoupling and thermal robustness up to +180°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Dedicated SENT output from die 1; enables independent signal path for redundancy validation and fault detection. |
| 2 | VSS | Common ground reference for both dies; must be low-impedance to ensure EMC stability and diagnostic accuracy. |
| 3 | VDD | Shared 4.5–5.5 V supply input; powers both dies; requires external 100 nF ceramic decoupling at package edge. |
| 4 | OUT2 | Dedicated SENT output from die 2; paired with OUT1 for cross-comparison, plausibility checking, and ASIL B compliance. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous measurement of Bx, By, Bz enables true 3D magnetic field analysis for absolute angle computation without mechanical stops. |
| Dual-Die Redundancy (SMP-4) | Two independent sensor dies in one mold provide hardware-level fault tolerance, meeting ISO 26262 ASIL B requirements without external supervision. |
| Programmable 17-Point Linearization | Corrects nonlinearity across full 0–360° range using user-defined transfer curve points, eliminating need for external calibration lookup tables. |
| SENT Diagnostics | Embedded error codes, broken-wire detection (92.5–99.5% VDD level reporting), and configurable field threshold alerts reduce ECU software overhead. |
| High-Temp Operation | Validated operation at +180°C ambient for ≤250 h in SMP-4 package, enabling placement near hot engine zones without heatsinking. |

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 |
|---|---|---|---|
| MLX90421GVD-ADD-030-TU | Single-die SMP-4 variant; lacks dual-output redundancy and ASIL B SEooC certification; identical SENT protocol and linearization capability. | Applicable where functional safety requirements are ASIL A or QM only; not suitable for throttle or steering where dual-die validation is mandated. | Select when cost optimization is prioritized over fault tolerance and safety certification. |
| TLV493DW2B6HTSA1 | Infineon 3D Hall sensor with I²C output; ±0.5° accuracy; no SENT support; operates −40°C to +125°C; no ASIL certification. | Used in non-safety-critical industrial encoders or consumer devices; requires external microcontroller for SENT conversion and diagnostics. | Choose for space-constrained I²C systems where SENT interface and automotive qualification are not required. |
Compared with MLX90422GVD-ADD-030-TU, the MLX90421GVD-ADD-030-TU reduces redundancy but retains identical packaging and programming flexibility, while the TLV493DW2B6HTSA1 trades SENT output and ASIL B compliance for I²C simplicity and lower temperature rating - making each alternative suitable only in contexts where those specific capabilities are non-essential.

FAQ
What is the primary sensing technology used in the MLX90422GVD-ADD-030-TU?
The MLX90422GVD-ADD-030-TU uses Melexis' proprietary Triaxis® Hall technology, which simultaneously measures all three orthogonal components (Bx, By, Bz) of the applied magnetic field. This enables robust absolute angular position calculation from a single moving magnet without mechanical constraints, and forms the basis for its programmable sensing modes and high immunity to stray fields.
Does the MLX90422GVD-ADD-030-TU support SENT output with pause pulse or without pause?
Yes, the MLX90422GVD-ADD-030-TU supports both SENT with pause pulse (default factory setting, 287-tick frames) and SENT without pause (user-configurable). The choice affects timing behavior: synchronous mode offers fixed 861–905 μs refresh with 1.32–2.03 ms latency, while asynchronous mode allows variable frame length (up to 270 ticks) and lower average latency down to 0.83 ms under optimal conditions.
What safety certifications apply to the MLX90422GVD-ADD-030-TU?
The MLX90422GVD-ADD-030-TU is certified as an ISO 26262 ASIL B Safety Element out of Context (SEooC) and qualified per AEC-Q100 Grade 0 (−40°C to +160°C). Its dual-die SMP-4 implementation enables hardware-level redundancy, including independent output paths (OUT1/OUT2), cross-die diagnostics, and built-in watchdog timers - all documented in the official Melexis Safety Manual Rev. 004.
Can the MLX90422GVD-ADD-030-TU be programmed for linear position sensing?
Yes, the MLX90422GVD-ADD-030-TU supports both angular rotary and linear position sensing modes via end-user programming. The magnetic configuration option "0" in the ordering code (ADD-030) explicitly denotes Angular Rotary / Linear Position capability, and the DSP allows full reconfiguration of the transfer characteristic - including 17-point linearization - to match custom magnet trajectories in either domain.
What is the maximum ambient temperature rating for the MLX90422GVD-ADD-030-TU in SMP-4 package?
The MLX90422GVD-ADD-030-TU in SMP-4 package is rated for continuous operation from −40°C to +160°C ambient, with extended high-temperature capability up to +180°C for ≤250 hours. This extension is validated only for SMP-3, SMP-4, and DMP-4 packages and requires adherence to voltage derating limits specified in Table 10 of the datasheet Rev. 004.
