Brief Description

The KTU1001 is a Hi-Speed (up to 480Mbps) USB dual

SPDT (single-pole/double-throw) switch with overvoltage

protection. This device operates over a 2.7V to 5.5V input

supply range with over voltage fault protection up to 20V.

USB Type-C features high voltage charging where the

KTU1001 protects USB data lines from short circuit and

surge events that can permanently damage the mobile

system. The device features independent control bits for

each switch pair and an on/off enable (̅E̅̅N̅) for shutdown

mode. Additional features include low switch on resistance

and capacitance along with a fault flag (̅F̅L̅̅A̅̅G̅̅) to alert the

system processor to overvoltage fault events.

Similar in features and performance to KTU1000, the

KTU1001 adds reverse blocking MOSFET switch

functionality.

The KTU1001 has low power consumption and is available

in an ultra-small 12-Bump 1.17mm x 1.57mm WLCSP

package making it an ideal solution for USB interface

switching and protection in mobile applications.
