USB Type‐A and USB Type‐C have separate power and charging specifications under the USB Implementers Forum, Inc (USB‐IF). There is no way for Type‐A ports to share a power budget with Type‐C ports due to limitations in the specifications. Additionally, in many applications that have a strict power budget, it is not possible to supply every USB port on the host system with the necessary power to classify it as a charging or power delivery port. The circuit outlined in this document allows for every port – Type‐ A or Type‐C – on a system to become a charging‐capable or power‐delivery capable port without expanding or taking a greater percentage of the host system’s power budget.
