USB 3.1 Type C Circuit Protection

Littelfuse USB 3.1 Type C Circuit Protection delivers overcurrent and electrostatic discharge (ESD) protection while maintaining USB 3.1 Type C data integrity. The host and all self-powered hubs must implement overcurrent protection for safety purposes and the hub must have a way to detect the overcurrent condition and report it to the USB software. Polymeric PTCs from Littelfuse provide an ideal solution for overcurrent protection. Promoting high signal integrity on the data lines of USB 3.1 Type C interfaces offers benchmark-settling, silicon-based, low-capacitance ESD protection while providing effective ESD protection on the VBUS, USB 2.0, and control lines of the interface.
