Simply speaking, CCG3PA are more flexible, we can customize firmware for CCG3PA but not BCR. The main differences are:
1. BCR cannot support power bank design.
2. CCG3PA can support one Type-C port and one Type-A port, but BCR can only support one Type-C port.
3. CCG3PA can support more legacy charge protocols.
For more information, kindly read Overview, datasheet, EVK Guide, etc.
BCR will be a game changer for barrel connector products.
A device, such as a speaker, shaver, power tools, modem etc. that use a barrel connector for power will benefit from using a universal power interface such as USB Type-C (by BCR).
