Product details
Overview
MLX90422GVS-ADD-033-TU 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 SENT output (SAE J2716 APR2016), and operates from −40°C to +160°C in DMP-4 package. It delivers 12-bit angular resolution with ±0.5° total accuracy and supports linearization up to 17 points for throttle or pedal position sensing.
For engineers reviewing the MLX90422GVS-ADD-033-TU datasheet, pinout, applications, or equivalent options, key selection criteria include SENT A.3 (H.4) frame compliance, DMP-4 PCB-less packaging, ISO26262 ASIL B safety element out of context, AEC-Q100 Grade 0 qualification, and programmable transfer characteristic for non-contacting potentiometer replacement.
Technical Context
The MLX90422GVS-ADD-033-TU implements Triaxis® Hall technology to measure Bx, By, and Bz magnetic field components simultaneously. Its on-chip DSP performs real-time angle calculation using user-programmable linearization with up to 17 points and configurable filtering (Filter 0/1/2).
It outputs SENT frames with fixed 3 μs tick time, defaulting to synchronous acquisition mode with 287-tick frames (861–905 μs refresh), 1.32–2.03 ms average latency, and 2.71–3.61 ms worst-case step response. The device supports both single-die DMP-4 packaging and dual-die redundancy variants - this variant is single-die.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Protocol | SENT per SAE J2716 APR2016, A.3 (H.4) format with pause pulse - enables robust digital transmission to automotive ECUs with CRC and diagnostics. |
| Angular Accuracy | ±0.5° total error over −40°C to +160°C - ensures reliable pedal/throttle position feedback without recalibration across full automotive temperature range. |
| Resolution | 12-bit (4096 steps per 360°) - provides fine-grained position discrimination for high-fidelity control loops. |
| Supply Range | 4.5 V to 5.5 V - compatible with standard automotive 5 V supply rails and tolerant of battery transients. |
| Startup Time | 5.93 ms to first valid angle - meets fast-boot requirements for engine control and transmission systems. |
| Magnetic Sensitivity | Supports X-Y plane flux ≥70 mT and Z-axis ≥126 mT - enables compact magnet designs with air gaps up to 4 mm in rotary configurations. |
| Functional Safety | ISO26262 ASIL B Safety Element out of Context - allows integration into ASIL B systems without requiring additional safety mechanisms at IC level. |
Pinout & Package
DMP-4 is a PCB-less dual-mold package with 4 leads, optimized for direct soldering onto flexible substrates or stamped metal carriers. It integrates decoupling capacitance internally and supports automated assembly with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog and digital domains - must be connected to low-impedance chassis ground for EMC stability. |
| 2 | VDD | 5 V supply input - accepts 4.5–5.5 V with 8.5 mA typical current draw; internal regulator generates 3.3 V analog rail. |
| 3 | OUT | Open-drain SENT output - requires external pull-up to Vext (VDD); drives standard 10–55 kΩ load per SAE J2716. |
| 4 | VSS | Second ground terminal - improves thermal dissipation and reduces ground loop impedance in high-noise environments. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Simultaneous Bx, By, Bz measurement enables true absolute angle computation from rotating magnets without mechanical stops or index pulses. |
| Programmable Linearization | Up to 17-point user-defined transfer curve compensates for magnet nonlinearity and mechanical eccentricity in production assemblies. |
| SENT Diagnostics | Embedded broken-wire detection (99.5% VDD on open VSS; 92.5–98.7% VDD on open VDD) and CRC-protected frames reduce ECU diagnostic overhead. |
| AEC-Q100 Grade 0 | Qualified for operation from −40°C to +160°C ambient - validated for under-hood applications including turbocharger actuators and transmission shifters. |
| DMP-4 Packaging | PCB-less dual-mold construction eliminates FR4 substrate, reducing height to 1.1 mm and enabling integration into space-constrained mechanical housings. |

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-033-TU | Single-die predecessor with identical DMP-4 package and SENT A.3 output, but limited to 12-point linearization and no ASIL B certification. | Lacks ISO26262 ASIL B SEooC documentation and has reduced diagnostic coverage - suitable only for non-safety-critical industrial use. | Select when cost sensitivity outweighs functional safety requirements and legacy design reuse is prioritized. |
| AMS AS5600-WSCT | I²C output (not SENT), 12-bit resolution, ±0.3° accuracy, no AEC-Q100 qualification, operates to +85°C only. | Requires external microcontroller for protocol translation and lacks automotive-grade thermal robustness - limited to cabin or low-temp industrial encoders. | Choose only for non-automotive applications where I²C interface and lower ambient temperature suffice. |
Compared with MLX90422GVS-ADD-033-TU, the MLX90421 variant omits ASIL B safety evidence and offers fewer linearization points, while the AS5600 lacks SENT output, automotive qualification, and high-temperature operation - making MLX90422GVS-ADD-033-TU the sole option meeting full ASIL B, SENT, and Grade 0 requirements in DMP-4 form factor.

FAQ
What is the operating temperature range of the MLX90422GVS-ADD-033-TU?
The MLX90422GVS-ADD-033-TU is rated for continuous operation from −40°C to +160°C ambient temperature and qualified to AEC-Q100 Grade 0. It supports short-duration exposure up to +180°C in DMP-4 package configurations, with degraded performance parameters documented in the datasheet's high-temperature extension section. This range covers under-hood locations such as throttle bodies and transmission shifters.
Does the MLX90422GVS-ADD-033-TU require external passive components?
No, the MLX90422GVS-ADD-033-TU in DMP-4 package integrates internal decoupling capacitance and requires only an external pull-up resistor on the OUT pin (10–55 kΩ to VDD). No external capacitors, resistors, or magnetics are needed for basic operation - simplifying PCB layout and reducing bill-of-materials cost in space-constrained modules.
How is the SENT output of the MLX90422GVS-ADD-033-TU configured by default?
The MLX90422GVS-ADD-033-TU ships factory-configured for SENT with pause pulse (A.3/H.4 format), 287-tick frames (861–905 μs duration), 3 μs fixed tick time, and two angle acquisitions per frame. It transmits CRC-protected data with built-in diagnostics including broken-wire detection and supports user programming of linearization points and magnetic thresholds via Melexis' PTC tool.
Can the MLX90422GVS-ADD-033-TU be used for linear position sensing?
Yes, the MLX90422GVS-ADD-033-TU supports both angular and linear position modes via configuration of its Triaxis® front end. In X-Z or Y-Z sensing mode, it computes displacement from magnet vertical or lateral movement, delivering SENT-encoded linear output with programmable transfer characteristics - validated for ride height and suspension travel applications.
Is the MLX90422GVS-ADD-033-TU pin-compatible with earlier Melexis Triaxis® sensors?
Yes, the MLX90422GVS-ADD-033-TU in DMP-4 package maintains pin-to-pin compatibility with prior-generation MLX903xx and MLX904xx devices in the same package, including identical 4-pin lead configuration (VSS-VDD-OUT-VSS) and mechanical footprint. This enables drop-in replacement in existing designs without PCB revision.
