USB-C UFP CC configuration: What Rd resistor value i need to use to be able to draw up to 3A?
If you are making UFP (Upstream Facing Port), which means "consuming device", you need 5.1k pull-downs on both CC wires. The max current to take is determined by provider (host) capability, which is "advertised" by means of PULL-UPs on host/provider side. If the pull-up is 56k, no more than 500/900 mA can be taken by consumer. If PU=22k, then the load can be up to 1.5A. If the PU=10k, the port can source up to 3 A. It is a responsibility of device to measure the voltage on its pull-down resistors, determine the source capability, and restrict its consumption in accord.
