USB-C immunity for robust power and high-speed connectivity

A scalable protection portfolio for modern USB-C applications

Beyond generic protection: A line-by-line approach to USB-C vulnerabilities

ST replaces generic protection with a line-by-line, evidence-based architecture. By matching power, control, and high-speed data paths with targeted immunity, ST enables resilient ports that preserve signal integrity and accelerate design confidence under real-world electrical conditions.
