Kinetic Technologies KTU1108 USB Type-C Protector for CC Pins

Kinetic Technologies KTU1108 USB Type-C™ Protector for CC Pins is designed for ESD, surge, and over-voltage protection (OVP) on USB Type-C ports' CC1 and CC2 (CC and V_CONN) lines. Kinetic KTU1108 offers an ultra-fast OVP response time of 15ns. The device meets IEC61000-4-5 surge protection standards, increasing immunity from power surges such as lightning strikes on the power lines while the USB cable is connected.

The KTU1108 is provided in an extremely small size in a single package solution for ESD, Surge, OVP, and moisture detection. The CC1/2 switches are low on-resistance to minimize power dissipation for passing V_CONN power up to 1.25A. Internal 5.1kΩ resistors automatically pull down on CC1/2 during dead battery conditions, ensuring that the upstream source provides 5V to VBUS. The KTU1108 is packaged in a RoHS and Green compliant 1.29mm x 1.69mm wafer-level chip-scale package (WLCSP).
