The CCG EVK base board consists of a DC input, a USB Type-C Redriving Switch IC, a DisplayPort input, a SuperSpeed
Type-B port, and one Type-C port. The CCG2 daughter card consists of the CCG2 device and a USB-Serial IC to provide a
USB interface for debugging and programming. The CC lines of the CCG2 device are connected to the Type-C port. The USB
Type-C Redriving Switch IC is controlled by the CCG2 device over an I
2
C interface.
The CY4521 EZ-PD CCG2 EVK has power provider and consumer path control circuitry to showcase EZ-PD CCG2
’s ability
to switch its power role from a provider to a consumer and vice versa. This EVK has over-voltage and over-current protection
circuitry for VBUS and it also supports programming of the EZ-PD CCG2 device over SWD and I
2
C interfaces. The EVK
supports PCs, notebooks, tablets, and other applications that would host a Type-C interface. It is primarily intended as an
evaluation vehicle for USB host systems that house a Type-C connector.
