Cypress' EZ-PD BCR is a highly-integrated USB Type-C port controller targeting electronic devices that have legacy barrel connectors (up to 100 W) or USB micro-B connectors for power such as drones, smart speakers, power tools, and other rechargeable devices. EZ-PD BCR complies with the latest USB Type-C and USB Power Delivery (PD) standards. It enables users to quickly convert their devices from being powered through a barrel connector to being powered via the USB-C connector with few external components and without requiring firmware development.
EZ-PD BCR integrates a complete USB Type-C transceiver, USB PD policy manager, a load switch controller with a soft start, all termination resistors required for a USB Type-C port, and system-level ESD protection.
Replace a barrel power connector with USB-C in three simple steps using the CY4533 EZ-PD BCR Kit:

Developers can use this reference design and the voltage divider guide to integrate BCR into their next design quickly. No firmware development is required.
Use VMIN and VMAX to set the VBUS voltage range to be provided by a USB-C power adapter.
Use ILIM_COARSE and ILIM_FINE to set the maximum current to be provided by a USB-C power adapter.
Maximum current = ILIM_COARSE + ILIM_FINE
