4-Channels of IEC 61000-4-2 ESD Protection (CC1, CC2, SBU1, SBU2 Pins)

The TPD4S311 integrates 4-Channels of IEC 61000-4-2 system level ESD protection for the CC1, CC2, SBU1, and SBU2 pins. USB Type-C ports on end-products need system level IEC ESD protection in order to provide adequate protection for the ESD events that the connector can be exposed to from end users. The TPD4S311 integrates IEC ESD protection for all of the low-speed pins on the USB Type-C connector in a single chip. Also note, that while the RPD_Gx pins are not individually rated for IEC ESD, when they are shorted to the C_CCx pins, the C_CCx pins provide protection for both the C_CCx pins and the RPD_Gx pins. Additionally, high-voltage IEC ESD protection that is 24-V DC tolerant is required for the CC and SBU lines in order to simultaneously support IEC ESD and Short-to-VBUS protection; there are not many discrete market solutions that can provide this kind of protection. The TPD4S311 integrates this type of high-voltage ESD protection so a system designer can meet both IEC ESD and Short-to-VBUS protection requirements in a single device.
