US Patent 10949375 Methods and apparatus for an interface

Various embodiments of the present technology may provide methods and apparatus for an interface. The interface may be configured to detect a hot unplug condition based on a first output voltage at an output terminal of a first buffer circuit and a second output voltage at an output terminal of a second buffer circuit, wherein the first and second buffer circuits receive a common input. The interface may further detect the hot unplug condition based on a difference of a peak magnitude of the first output voltage and a peak magnitude of the second output voltage.
