Abstract:
A device includes a USB-C controller instantiated as a first integrated circuit that includes a first set of host terminals coupled to host controllers and a second set of terminals coupled to sets of D+/D− terminals of a type-C receptacle. A D+/D− multiplexer is to selectively couple the first set of host terminals to the second set of terminals. An electrostatic discharge (ESD) protection circuit is coupled between the D+/D− multiplexer and the second set of terminals. A charger detector circuit is coupled between a positive data system terminal and a negative data system terminal of the first set of terminals, the charger detector circuit to detect whether the second set of terminals is coupled to a USB charger through the type-C receptacle.
