Product details
Overview
MLX90422GVE-ADD-030-SP 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 linearization (up to 17 points), SENT A.3 (H.4) output per SAE J2716 APR2016, and operates from -40°C to +160°C in SMP-3 package. Used in automotive throttle and pedal position sensing where non-contact, high-temperature robustness and ASIL B functional safety are required.
For engineers reviewing the MLX90422GVE-ADD-030-SP datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, SENT timing behavior, magnetic field sensitivity (Bz up to 126 mT), ISO26262 ASIL B safety element out of context compliance, and SMP-3 package-specific design meaning - all confirmed from Melexis Revision 004 datasheet (March 2026).
Technical Context
The MLX90422GVE-ADD-030-SP implements Triaxis® Hall sensing to measure Bx, By, and Bz components simultaneously, enabling absolute angular position calculation (0–360°) via on-chip DSP with user-programmable transfer characteristics. Its SENT output uses fixed 3 μs tick time, supports A.3 (H.4) format with pause pulse, and delivers diagnostic data including error codes and user-defined values.
It operates in continuous synchronous acquisition mode by default (2 angle acquisitions per frame), achieving 1.32–2.03 ms average latency and 2.71–3.61 ms worst-case step response. The SMP-3 package (3-pin, PCB-less) integrates decoupling capacitance and supports high-temperature extension up to +180°C for ≤250 h.

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 |
|---|---|---|---|
| MLX90421GSE-ADD-030-SP | SMP-3 package, same pinout, but SENT A.1 (H.1) dual-throttle format - lacks A.3 (H.4) extended diagnostics and 17-point linearization (max 9 points). | Targeted for cost-sensitive dual-throttle applications only; not suitable for single-sensor high-diagnostic-demand use cases like steering angle. | Select MLX90421GSE-ADD-030-SP only when dual-throttle SENT framing and reduced linearization depth meet system requirements. |
| AMS AS5600-DSF | 3.3 V-only I²C interface, no SENT output; ±0.3° typical accuracy; no ASIL B certification; operates to +85°C only. | Designed for consumer/industrial encoders - lacks automotive qualification, high-temp capability, and functional safety evidence required for OEM drivetrain modules. | AMS AS5600-DSF is viable only in non-automotive, low-temperature, non-safety-critical rotary sensing where I²C integration is preferred over SENT. |
Compared with MLX90422GVE-ADD-030-SP, MLX90421GSE-ADD-030-SP offers identical packaging and pinout but sacrifices diagnostic depth and linearization flexibility, while AMS AS5600-DSF trades automotive robustness and safety compliance for simpler digital interfacing - making MLX90422GVE-ADD-030-SP the sole choice for ASIL B-compliant, high-temperature, SENT-based absolute position sensing.
