Introduction

EZ-PD CCG3PA belongs to Cypress's family of USB Type-C controllers that complies with the latest USB Type-C
and Power Delivery (PD) standards. In addition, with the built-in overvoltage protection (OVP) and overcurrent
protection (OCP), it helps 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.

    It performs nonintrusive probing, and captures accurate protocol messages on the CC line. This analyzer consists of Cypress‘s programmable MCU (PSoC 5LP), which monitors the data on the CC line and sends the data to the host application over a USB interface. The Type-C plug and Type-C receptacle on this analyzer provide a pass-through for the Power Delivery (PD) packets transmitted between each Type-C PD connection.
