Introduction  
EZ-PD CCG3PA belongs to Cypress’ family of USB Type-C controllers that comply with the latest USB Type-C and  
Power Delivery (PD) standards. In addition, built-in overvoltage protection (OVP) and overcurrent protection (OCP)  
help to reduce the need for additional components and the overall cost of a Type-C ecosystem. Typical applications  
using CCG3PA include mobile power adapters, PC power adapters, power banks, and car chargers.
