Abstract

Modern automotive systems increasingly rely on distributed electronics operating across multiple ground domain. Ground potential differences caused by high current loads, long cable runs, switching noise, or intentional ground offset scan disrupt low-voltage digital communication and compromise system reliability.

This application note introduces Texas Instruments Ground-Level Voltage Translation (TXG) family, and explains how the TXG family addresses static and dynamic ground offset issues enabling reliable communication across ground mismatches in automotive systems without requiring galvanic isolation.
