Product details

Overview

MLX90422GVS-ADD-030-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 processing, and SENT (SAE J2716 APR2016) output. Operating from −40°C to +160°C with ±10 mT useful magnetic flux density norm and 1.32–2.03 ms average latency, it delivers robust non-contacting angle measurement in automotive pedal and throttle systems.

For engineers reviewing the MLX90422GVS-ADD-030-TU datasheet, pinout, applications, or equivalent options, key selection criteria 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 AEC-Q100 Grade 0 qualification.

Technical Context

The MLX90422GVS-ADD-030-TU implements Triaxis® Hall technology to measure Bx, By, and Bz magnetic field components simultaneously. Its on-chip DSP performs real-time angular calculation using user-programmable transfer characteristics with up to 17 calibration points, enabling precise absolute position extraction from rotating magnets without mechanical contact.

It operates in continuous synchronous acquisition mode by default, delivering SENT frames at fixed 861–905 μs intervals with 3 μs tick time and A.3 (H.4) encoding. The device supports dual-die redundancy only in TSSOP-16 (GO), while this variant uses single-die DMP-4 packaging with built-in decoupling capacitors and straight leads (ADD-030).

FAQ

What is the operating temperature range of the MLX90422GVS-ADD-030-TU?

The MLX90422GVS-ADD-030-TU operates from −40°C to +160°C ambient temperature. It also supports high-temperature extension up to +180°C for ≤250 hours in DMP-4 packages like this one, with specified performance degradation per Table 10 of the datasheet. This makes MLX90422GVS-ADD-030-TU suitable for under-hood automotive placements where thermal stress exceeds standard Grade 0 limits.

Does the MLX90422GVS-ADD-030-TU require external decoupling capacitors?

No, the MLX90422GVS-ADD-030-TU in DMP-4 packaging integrates decoupling capacitors internally, eliminating the need for external VDD/VSS bypass components. Pin 1 and Pin 4 are both ground terminals, and Pin 2 is the supply input-no additional ceramic capacitors are required on the PCB, simplifying layout and reducing bill-of-materials count for MLX90422GVS-ADD-030-TU implementations.

What SENT protocol version does the MLX90422GVS-ADD-030-TU implement?

The MLX90422GVS-ADD-030-TU implements SENT per SAE J2716 APR2016, specifically using the Single Secure Sensor A.3 (H.4) frame format by default.

Can the MLX90422GVS-ADD-030-TU be programmed for custom transfer characteristics?

Yes, the MLX90422GVS-ADD-030-TU supports end-user programming of its linear transfer characteristic with up to 17 calibration points via its NVRAM. This allows precise correction of magnetic nonlinearity across the full 0–360° range, enabling MLX90422GVS-ADD-030-TU to achieve <±0.5° INL after calibration-even with asymmetric magnet geometries or mechanical tolerances in final assembly.

Is the MLX90422GVS-ADD-030-TU certified for functional safety applications?

Yes, the MLX90422GVS-ADD-030-TU is certified as an ISO26262 ASIL B Safety Element out of Context (SEooC) and qualified to AEC-Q100 Grade 0.
