The FA2219 is a single-chip USB Type-C active cable port protection device that provides 48V Short-to-VBUS protection. The FA2219 enables the CC and VCONN pins to be 48V tolerant without interfering with normal operation by providing over-voltage protection on the CC and VCONN pins. The device places high voltage FETs in series on the CC and VCONN 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.
