Brief Description

The KTU1001A 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

KTU1001A 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 (?E??N?) for shutdown

mode. Additional features include low switch on resistance

and capacitance along with a fault flag (?F?L??A??G??) to alert the

system processor to overvoltage fault events.

Similar in features and performance to KTU1000, the

KTU1001A adds reverse blocking MOSFET switch

functionality.

The KTU1001A 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.
