Overview of USB Type‑C Interface, Data and Power Roles, and PD Charging Process
The USB‑Type C connector introduces a reversible plug with E‑Marker‑enabled cables, supports up to 10 Gb/s data and 100 W power delivery, negotiates data and power roles via the CC pins, and uses the USB‑PD protocol over those pins to dynamically select voltage‑current profiles for fast charging.
