The FA2211 is a single-chip USB Type-C port protection device that provides 20V Short-to-VBUS protection. The FA2211 enables the CC and SBU pins to be 20V tolerant without interfering with normal operation by providing over-voltage protection on the CC and SBU pins. The device places high voltage FETs in series on the CC and SBU lines. When a voltage above the OVP threshold is detected on these lines, the high voltage switches are opened up, isolating the rest of the system from the high voltage condition present on the connector.
Most systems require IEC 61000-4-2 ESD system level protection for external pins. The FA2211 integrates 8-channels of IEC 61000-4-2 ESD protection for eliminating the need to place externally TVS diodes on the connector side.
