General Description
The TS2021 is integrated 85mΩhigh-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.
