Figure 11 shows a CCG2 receptacle-based Power Adapter
application in which the CCG2 device is used as a DFP. CCG2
integrates all termination resistors and uses GPIOs (VSEL_0
and VSEL_1) to indicate the negotiated power profile. The VBUS
voltage on the Type-C port is monitored using internal ADC to
detect undervoltage and overvoltage conditions on VBUS. To
ensure quick discharge of VBUS when the power adapter cable
is detached, a discharge path is also provided.
