I have a USB-C peripheral device that will act as a charger for a mobile phone or laptop. The peripheral requires a modest amount of power (e.g., much lower power than what it delivers to the connected device) to operate. In the interest of keeping a single connector design and eliminating the need for a battery on the peripheral, is it possible to source and sink power simultaneously through a USB-C DRP port? If not, is it possible to tap off VCONN for peripheral bias?
