Product details

Overview

MLX90421GVS-ADC-000-SP from Melexis is a Triaxis® monolithic magnetic position sensor IC for absolute rotary and linear position sensing. It integrates a 3-axis Hall front end, DSP-based signal conditioning, and programmable ratiometric analog or PWM output. Operating from −40°C to +160°C with AEC-Q100 Grade 0 qualification and ISO 26262 ASIL B safety certification, it delivers ±0.5° angular accuracy in automotive pedal and throttle position systems.

For engineers reviewing the MLX90421GVS-ADC-000-SP datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DMP-4), validated pin functions, confirmed Triaxis® 3D magnetic field processing, real-world accuracy specs, and two rigorously cross-checked alternative parts for non-contacting position sensing designs.

Technical Context

The MLX90421GVS-ADC-000-SP uses Triaxis® Hall technology to measure all three orthogonal magnetic flux components (B_x, B_y, B_z) simultaneously, enabling robust absolute angle calculation without mechanical contact. Its on-chip DSP performs multi-point linearization (up to 17 points) and supports both analog and PWM output modes with programmable transfer characteristics.

It operates across −40°C to +160°C ambient temperature, features integrated diagnostics including broken-wire detection, and implements functional safety mechanisms compliant with ISO 26262 ASIL B as a Safety Element out of Context (SEooC). The DMP-4 package includes built-in decoupling capacitors and supports high-temperature extension up to +180°C for limited duration.

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
MLX90411GVS-ADC-000-SP	Single-axis Hall sensor; no Triaxis® B_y/B_z capability; lower accuracy (±1.5°); no ASIL B certification	Limited to simple rotary or linear motion with fixed magnet orientation; unsuitable for multi-degree-of-freedom or misaligned setups	Select only when cost sensitivity outweighs accuracy, safety, and design flexibility requirements
