KTU1108 USB Type-C Protector for CC Pins
■The KTU1108 provides ESD, surge, and over-voltage protection (OVP) for USB Type-C ports’ CC1 and CC2 (CC and VCONN) lines. 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 CC1/2 switches are low on-resistance to minimize power dissipation for passing VCONN power up to 1.25A. 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 KTU1108 is packaged in RoHS and Green compliant 1.29mm x 1.69mm wafer-level chip-scale package (WLCSP).
