Description

The KTU1131 provides four conducting paths with over-voltage protection (OVP) for Type-C’s CC, SBU signals. Once an over-voltage 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 on-capacitance 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 up-stream source provides 5V on VBUS.

Also, it contains clamping circuits aiming at D+/D- ESD protection, eliminating the need for external TVS diodes. Trivial capacitance is presented from those pins to ground to achieve USB Hi-Speed data integrity.
The KTU1131 is packaged in RoHS and Green compliant 3mm x 3mm UQFN package.
