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 (̅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
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.
