摘要
Aspects of the present disclosure provide for a circuit (102). In at least some examples, the circuit includes a dual-role port (124) for transferring power to the circuit and from the circuit. The circuit also includes a micro-processing unit (114). The micro-processing unit is configured to control the circuit to operate as a sink device to receive power from a source device via the dual-role port when the power supply includes a first amount of stored energy, detect, at the dual-role port, a change in a termination resistance of the source device, and control the circuit to limit power transfer from the circuit to the power supply via the dual-role port when the power supply changes in status from a sourcing state to a sinking state.
