Product details

Overview

MLX90422GVS-ADD-038-RX 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, and SENT (SAE J2716 APR2016) output. Operating from −40°C to +160°C, it delivers 12-bit angular resolution with ±0.5° total accuracy over temperature and supports programmable linear transfer characteristic up to 17 points. Used in automotive throttle and pedal position sensing.

For engineers reviewing the MLX90422GVS-ADD-038-RX datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DMP-4), SENT timing compliance, ISO26262 ASIL B safety element out of context status, AEC-Q100 Grade 0 qualification, and confirmed pin definitions for PCB-less dual-mold packaging.

Technical Context

The MLX90422GVS-ADD-038-RX implements Triaxis® Hall technology to measure B_x, B_y, and B_z components simultaneously, enabling robust absolute angle calculation from magnet motion. Its on-chip DSP performs real-time linearization using up to 17 user-programmable points and supports both synchronous and asynchronous SENT frame generation with fixed 3 μs tick time.

This variant uses the DMP-4 package (PCB-less dual mold), features SENT output compliant with SAE J2716 APR2016 A.3 (H.4) format, and includes built-in decoupling capacitors. It operates across −40°C to +160°C with supply voltage range 4.5–5.5 V and consumes 7.5–10.0 mA (single die).

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-RX	Same DMP-4 package and SENT A.3 (H.4) protocol; differs only in Trim & Form configuration (STD2 2.54 mm lead pitch vs. STD4 2.54 mm).	Identical functional performance; used where lead coplanarity or insertion force requirements differ.	Select MLX90422GVS-ADD-030-RX if board-level assembly uses standard pick-and-place tooling calibrated for STD2 form factor.
MLX90422GDC-ADD-038-RE	SOIC-8 package (DC) instead of DMP-4 (VS); same chip revision (ADD-038), same SENT configuration, but requires external decoupling capacitors.	Used where legacy SOIC footprint compatibility or higher thermal mass is prioritized over space savings.	Choose MLX90422GDC-ADD-038-RE only when redesigning existing SOIC-8 layouts; DMP-4 offers superior EMC and reduced component count.

Compared with MLX90422GVS-ADD-038-RX, the 030-RX variant offers identical sensing and output functionality with minor mechanical differences, while the DC-038-RE version trades PCB-less integration for package familiarity and higher thermal inertia - neither is pin-compatible, but all share identical SENT timing, accuracy, and safety certification.

The MLX90422GVS-ADD-038-RX is rated for −40°C to +160°C ambient operation per AEC-Q100 Grade 0 qualification. It can withstand short-term exposure up to +180°C (≤250 hours) in DMP-4, SMP-3, and SMP-4 packages, with degraded but functional performance - validated for placement near turbochargers and transmission valve bodies.

How is functional safety addressed in MLX90422GVS-ADD-038-RX?

The MLX90422GVS-ADD-038-RX is certified as an ISO26262 ASIL B Safety Element out of Context (SEooC). It includes hardware-level diagnostics: CRC validation, broken-wire detection on VSS/VDD, watchdog timers, and memory ECC. These mechanisms enable integration into ASIL B systems without requiring additional safety hardware, provided correct configuration and diagnostic monitoring per Melexis safety manual.

Can MLX90422GVS-ADD-038-RX measure linear position?

Yes. Though optimized for rotary applications, the MLX90422GVS-ADD-038-RX supports linear position sensing via X-Z or Y-Z magnetic configurations.
