The CY4532 EVK supports mobile power adapters, PC power adapters, power banks, car chargers, and other
applications that primarily charge other devices via a Type-C interface. The kit is intended as an evaluation vehicle for
USB Host systems that house a Type-C connector. Refer to the CY4532 EZ-PD CCG3PA EVK Guide for in-depth
information about EVK use cases.
The CY4532 Main Board consists of the following:
CCG3PA silicon (CYPD3171-40LQXIT)
Type-C port
Type-A ports
MiniProg3 SWD header
Debug header The CY4532 Power Board consists of the following:
DC Input
Battery Input Terminal
Mini-USB interface (to download firmware into CCG3PA)
Type-C port (to enable flashing of an external CCG3PA-based hardware)
Regulators (to support battery charging and provide power for the Type-C interface)
Type-A charging
The Main Board is mounted on the Power Board using two sets of connectors.
The CY4532 CCG3PA silicon contains overvoltage protection (OVP) and overcurrent protection (OCP) circuitry for
VBUS and supports EZ-PD CCG3PA device programming over the Type-C interface.
