The STMicroelectronics USB type-C protection for source application is a MCU companion chip enabling cost-effective USB-C source solution. It provides protections and functionalities to safely comply with the USB-C specification. It features 24 V tolerant ESD protection as per IEC61000-4-2 level 4 on USB type-C connector communication channel pins (CC). Also, it provides overvoltage protection on CC1 and CC2 pins when these pins are subjected to short circuit with the VBUS pin that may happen when removing the USB type-C cable from its receptacle.
