> I understand the complexity for data, but for power I wish it was as simple as power & ground wires and that's it. The minimum requirements are that you have to support the USB 2.0 protocol: > While BC1.2 is still supported over USB Type-C because it depends on the USB2.0 lane, a significantly simplified and higher power current capability mechanism is also implemented. This simplified approach involves resistor pull-down/ pull-up relationships. These pull-down/pull-up resistors are connected to the CC wire and the upstream facing port (UFP) must monitor the voltage on the CC1 and CC2 pins in order to detect the current sourcing capability of the down- stream facing port (DFP) it is connected to. This is a substantial improvement over the complicated handshake mech- anisms involved with USB BC1.2. > The basic USB Type-C current capabilities are Default USB (500mA for USB2.0 and 900mA for USB3.0), 1.5A@5V, and 3A@5V. * https://ww1.microchip.com/downloads/en/appnotes/00001953a.pdf https://ww1.microchip.com/downloads/en/appnotes/00001953a.pd...
