TS2023

1A Single Channel USB Power Switch

1/8

Version: A11

SOT-25

General Description

The TS2023 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 TS2023 is ideal for

any system where current limiting and power control are desired. The TS2023 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.
