DESCRIPTION
The AIC6170 is an integrated mOhm high-side power switch for self-powered and bus-powered Universal Serial Bus (USB) applications. This switch operates with input ranging from 3.0V to 5.5V, making it ideal for 5V systems.
The protection schemes include programmable current limiting with foldback, thermal shutdown and short circuit protection. The AIC6170 is ideal for any system where current limiting and power control are desired. The low quiescent current and small package of the AIC6170 makes it particularly suitable for battery-powered portable devices.
The Guaranteed minimum output rise-time which limits inrush current as well as minimizes EMI during hot plug-in prevents the voltage at upstream port from dropping excessively.
