Product details
Overview
MLX90422GVS-ADD-033-RE from Melexis is a Triaxis® monolithic magnetic position sensor IC for absolute rotary position sensing, featuring SENT output per SAE J2716 APR2016, programmable 17-point linear transfer characteristic, ISO26262 ASIL B Safety Element out of Context, and AEC-Q100 Grade 0 qualification. It operates from −40°C to +160°C and delivers robust non-contacting angular measurement in automotive pedal and throttle systems.
For engineers reviewing the MLX90422GVS-ADD-033-RE datasheet, pinout, applications, or equivalent options, key selection criteria include its DMP-4 package with trim-and-form STD2 2.54 mm lead pitch, SENT A.3 (H.4) frame format, 3 μs fixed tick time, dual-mold PCB-less construction, and built-in decoupling capacitors enabling simplified board layout.
Technical Context
The MLX90422GVS-ADD-033-RE integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, an analog-to-digital signal conditioner, and a DSP for real-time angle calculation and user-programmable linearization. Its architecture supports both X-Y and X-Z sensing modes via configurable IMC gain (GIMC = 1.19).
It implements continuous synchronous acquisition by default, delivering SENT frames every 861–905 μs with 287-tick length, 1.32–2.03 ms average latency, and 2.71–3.61 ms worst-case step response. The device uses internal 24 MHz main clock (±5% tolerance) and 1 MHz auxiliary clock, both trimmed at 35°C with thermal drift ≤ ±3.5%.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Protocol | SENT per SAE J2716 APR2016, A.3 (H.4) format with pause pulse - enables deterministic timing and CRC-protected diagnostics in automotive ECUs. |
| Tick Time | Fixed 3 μs - defines resolution and frame timing; not user-adjustable, ensuring consistent SENT timing across operating conditions. |
| Operating Temp | −40°C to +160°C - qualified for under-hood automotive applications including pedal and throttle position sensing. |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5 V automotive power rails; includes overvoltage (6.25 V) and undervoltage (3.90 V) detection. |
| Supply Current | 7.5–10.0 mA - single-die current draw; enables low-power operation without external regulators in DMP-4 configuration. |
| Angle Linearity | Programmable 17-point transfer curve - allows precise compensation for magnet nonlinearity and mechanical tolerances in rotary assemblies. |
| Safety Certification | ISO26262 ASIL B SEooC - provides safety mechanisms documented in Melexis safety manual for integration into ASIL B systems. |
Pinout & Package
DMP-4 (Dual Mold Package) is a PCB-less, surface-mount package with 4 leads, integrated decoupling capacitors, and STD2 2.54 mm lead pitch (trim-and-form option ADD-033). Designed for high-volume automotive assembly with RoHS compliance and enhanced EMC behavior.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog and digital sections; must be connected to PCB ground for EMC stability. |
| 2 | VDD | Primary 4.5–5.5 V supply input; powers internal regulator generating 3.3 V analog rail (VDEC). |
| 3 | OUT | Open-drain SENT output; requires external pull-up to Vext (≤ VDD); supports broken-wire diagnostics at 99.5% VDD. |
| 4 | VSS | Second ground terminal - improves current return path integrity and reduces ground bounce in noisy environments. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous Bx, By, Bz measurement enables true 3D magnetic field analysis for absolute angular position without mechanical stops. |
| On-chip DSP Linearization | 17-point programmable transfer curve compensates for magnet geometry and air-gap variation, reducing system-level calibration effort. |
| Built-in Decoupling | Integrated capacitors in DMP-4 eliminate need for external VDD/VSS bypass components, saving PCB area and improving EMI immunity. |
| SENT Diagnostics | Embedded error codes, passive diagnostic outputs (broken-wire), and configurable field thresholds (BTH_LOW/BTH_HIGH) support functional safety monitoring. |
| AEC-Q100 Grade 0 | Qualified for 160°C ambient operation with extended 180°C capability (≤250 h) in DMP-4 package - meets engine compartment thermal requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90422GVS-ADD-030-RE | Same DMP-4 package and SENT A.3 (H.4) protocol, but uses standard straight leads (not trim-and-form STD2 2.54 mm). | Requires different pick-and-place tooling and solder paste stencil; less optimized for tight-pitch automated assembly. | Select when legacy board layout or standard lead form factor is required; identical electrical and magnetic performance. |
| MLX90422GDC-ADD-030-RE | SOIC-8 package with separate VDEC decoupling pin; no built-in capacitors; requires external 100 nF VDD–VSS bypass. | Higher PCB footprint and component count; better suited for prototyping or designs requiring test access to VDEC. | Choose for development platforms or where SOIC-8 reflow compatibility or debug access outweighs DMP-4's space savings. |
Compared with MLX90422GVS-ADD-033-RE, the ADD-030 variant offers identical sensing and output functionality but lacks the optimized lead pitch for high-density automotive modules, while the SOIC-8 version trades compactness and integrated decoupling for greater layout flexibility and testability.

FAQ
What is the pin configuration of the MLX90422GVS-ADD-033-RE?
The MLX90422GVS-ADD-033-RE uses the DMP-4 package with four terminals: Pin 1 (VSS), Pin 2 (VDD), Pin 3 (OUT), and Pin 4 (VSS). Both ground pins must be connected to PCB ground for optimal EMC performance and thermal dissipation. No test or NC pins are present in this variant.
Does the MLX90422GVS-ADD-033-RE support programmable linearization?
Yes, the MLX90422GVS-ADD-033-RE supports up to 17-point programmable linear transfer characteristic via its NVRAM. This enables precise correction of magnet-induced nonlinearity and mechanical misalignment in rotary applications such as throttle bodies or pedal linkages.
What SENT protocol version does the MLX90422GVS-ADD-033-RE implement?
The MLX90422GVS-ADD-033-RE implements SENT per SAE J2716 APR2016, specifically the Single Secure Sensor A.3 (H.4) format with pause pulse. It uses a fixed 3 μs tick time and delivers frames every 861–905 μs in default synchronous mode.
Is the MLX90422GVS-ADD-033-RE qualified for automotive under-hood use?
Yes, the MLX90422GVS-ADD-033-RE is AEC-Q100 Grade 0 qualified (−40°C to +160°C) and ISO26262 ASIL B Safety Element out of Context certified. Its DMP-4 package supports extended 180°C operation for up to 250 hours, meeting stringent engine bay thermal requirements.
Does the MLX90422GVS-ADD-033-RE require external decoupling capacitors?
No, the MLX90422GVS-ADD-033-RE in DMP-4 package integrates decoupling capacitors internally. This eliminates the need for external VDD–VSS bypass components, reducing bill-of-materials cost and PCB area while improving noise immunity in high-EMI automotive environments.
