Abstract:
Circuits, methods, and apparatus that may compensate for an incompatibility between connection detection schemes used by different interface circuits for different connector receptacles. One example may provide an active pull-down that normally provides a pull-down resistor and provides an open circuit for a period of time following a disconnection of an interface from a cable.
