General Description

The TS2025 is integrated 90mΩ high-side power switch for self-powered and bus-powered Universal Serial Bus (USB) applications. This switch operates with input ranging from 2.7V to 6.5V, making it ideal for both 3V and 5V system. The protection includes current limiting with foldback, short circuit and thermal shutdown. Fault current is limited to typically 1A in accordance with the USB power requirements. The TS2025 is ideal for any system where current limiting and power control are desired. Guaranteed minimum output rise time limits inrush current during hot plug-in as well as minimizing EMI and prevents the voltage at upstream port from dropping excessively.
