KTU1120 USB Type-C™ Port Protector IC Kinetic Technologies KTU1120 USB Type-C™ Port Protector IC provides four conducting paths with overvoltage protection (OVP) for USB Type-C, CC, and SBU signals. Once an over-voltage event is detected, it will shut down all paths to protect circuits on the system side, like the PD controller from damage. All the SBU and CC switches have very low on capacitance for broad bandwidth to allow high-speed signals to pass through without loss. The CC1/2 switches have low on-resistance for passing VCONN power up to 1.25A.
