USB D+/D- Hi-Speed or SBU1/2 Switch with Fault Protection
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 ((“EN“)) for shutdown mode. Additional features include low switch on resistance and capacitance along with a fault flag ((“FLAG“)) 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.
