6.3.2 4-Channels of IEC 61000-4-2 ESD Protection (CC1, CC2, SBU1, SBU2 Pins)

The TPD4S480-Q1 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 TPD4S480-Q1 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 63V 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 TPD4S480-Q1 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.
