DESCRIPTION
The AIC6156 is integrated 60mohm high-side power switch for self-powered and bus-powered Universal Serial Bus (USB) applications. This switch operates with input ranging from 3.5V to 5.5V, making it ideal for 5V system.
The protection includes programmable current limiting with foldback, short circuit protection and thermal shutdown. The AIC6156 is ideal for any system where current limiting and power control are desired. The AIC6156 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.
