PPTC can protect against overcurrent faults in your circuit. So my question is how we can choose a PPTC device? What circuit's parameters in my design needed to determine first? And how to use those parameters to map manufacturer's catalogs. So there's a title of "Selection steps from the Catalog" which can be found in Fundamentals of PolySwitch Overcurrent and Overtemperature Devices. If you want to use PPTC in your USB circuit design, you can see "PTC Overcurrent Protection for Universal Serial Bus Circuit Designs" or "Meeting USB Overcurrent Protection Requirements" for help.
