Brief Description

The KTU1121 provides four conducting paths with

overvoltage protection (OVP) for USB Type-C CC and

SBU signals. Once an overvoltage event is detected, it

will shut down all paths to protect circuits in system side,

like PD controller from damage.

All the SBU and CC switches have very low oncapacitance

for broad bandwidth to allow high-speed

signal passing through without loss. The CC1/2 switches

have low on-resistance 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 on VBUS.

The KTU1121 is packaged in RoHS and Green

compliant 16-bump WLCSP 1.7mm x 1.7mm package

or 20 pin 3mm x 3mm TQFN package.
