The EZ-PD BCR controller is a new device in the USB Type-C family of devices from Cypress for power sink applications.
This device combines a certified USB Type-C r1.2 and Power Delivery r3.0 subsystem, high-voltage analog for protection and
monitoring, and a load switch controller in an easy-to-use package.
The CY4533 EVK features an onboard BCR controller which communicates with a USB Type-C power adapter to negotiate
for the proper voltage and current, as specified by onboard resistors. The DP, DM lines from the BCR controller are connected
to the Type-C connector for future usage.
