General Description

The TS2021 is integrated 85m?high-side power switch for self-powered and bus-powered Universal Serial Bus (USB) applications. This switch operates with input ranging from 3.2V to 6.5V, making it ideal for 5V system. The protection includes current limiting with foldback, short circuit and thermal shutdown. The TS2021 is ideal for any system where current limiting and power control are desired. The TS2021 has low quiescent current and small package, which is particularly suitable in battery powered portable application. 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.
