USB Type-C Port Protector for CC and SBU Pins
Description
The KTU1101 provides ESD, surge, and overvoltage protection (OVP) for USB Type-C ports CC and SBU signal pins. ESD protection meets IEC61000-4-2 standards, eliminating the need for external TVS diodes. Surge protection meets IEC61000-4-5 standards, increasing immunity from power surges such as lightning strikes on the power lines while the USB cable is connected. Overvoltage protection (OVP) eliminates system damage due to physical or moisture-related shorts between the signal pins and VBUS at elevated PD voltage levels.
The SBU switches have low on-capacitance for passing high-speed signals. The CC1/2 switches have low onresistance for passing VCONN power up to 1.25A for CC power delivery communications. During dead battery conditions, internal 5.1kΩ resistors automatically pull down on CC1/2 to ensure that the up-stream source provides 5V to VBUS.
The KTU1101 is packaged in RoHS and Green compliant 2.060mm x 1.720mm wafer-level chip-scale package (WLCSP).
