Product details
Overview
MLX90377GVS-ADB-300-RX from Melexis is a monolithic Triaxis® Hall-based magnetic position sensor IC for absolute rotary or linear position sensing. It delivers 12-bit ratiometric analog or PWM output in Standard/Legacy Mode, operates from -40°C to 160°C, supports 4.5–5.5 V regulated supply, and features stray-field robustness in DMP-4 package. Used in automotive pedal and throttle position sensing.
For engineers reviewing the MLX90377GVS-ADB-300-RX datasheet, pinout, applications, or equivalent options, key selection factors include its DMP-4 footprint, low-power analog/PWM output configuration, ASIL-B functional safety capability, and compatibility with non-contacting magnet-based position measurement systems requiring high temperature resilience.
Technical Context
The MLX90377GVS-ADB-300-RX integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, enabling absolute angular (0–360°) or linear displacement decoding via external magnet motion. Its on-chip DSP performs real-time signal conditioning and piecewise-linear transfer function mapping.
This variant implements Standard/Legacy Mode with programmable low-power analog or PWM output (not SENT/SPC), uses a single-die architecture in DMP-4 package, and meets ISO 26262 ASIL-B requirements for analog output mode as a Safety Element out of Context.
