KTU1108 USB Type-C Protector for CC Pins
●The KTU1108 provides ESD, surge, and over-voltage protection (OVP) for USB Type-Cports’CC1 and CC2 (CC and VCONN) lines. ESDprotection meets IEC61000-4-2 standards, eliminating the need for external TVS diodes.Surge protection meets IEC61000-4-5 standards, increasingimmunity from power surges such as lightning strikes on the power lines while the USB cable is connected. Overvoltage protection (OVP)eliminatessystem damage due to physicalor moisture-related shorts between the signal pins and VBUSat 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 resistorsautomaticallypull down on CC1/2to ensure that the up-stream source provides 5Vto VBUS.
●The KTU1108 is packaged in RoHS and Greencompliant 1.29mm x 1.69mm wafer-level chip-scalepackage (WLCSP).
