Brief Description

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 upstream

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).
