Brief 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

1.7mm x 2.1mm wafer-level chip-scale package

(WLCSP).
