The world’s first OVP IC designed specifically for CC and VCONN protection in active cables.
With the increasing adoption of the USB Type-C interface and the introduction of the PD 3.1 specification, which supports up to 240W (48V/5A), power protection has become more critical than ever.
In Type-C port designs, the pins are tightly spaced. During hot-plugging, under high humidity, or after prolonged use and thermal cycling, the metal of the pin contacts may deform, potentially causing short circuits between the high-voltage VBUS pin and low-voltage CC or VCONN pins.
This product provides 48V short-to-VBUS overvoltage protection for the CC and VCONN lines on the connector side. When the voltage exceeds the OVP threshold, the protection responds in just 100ns, quickly disconnecting the switch to prevent damage to CC and VCONN lines caused by overvoltage.
Furthermore, due to the limited space on active cable paddle cards, the FA2219 integrates ideal diode functionality within a compact 1.905mm x 1.905mm package, making it a direct replacement for discrete ideal diodes traditionally used on paddle cards.
