AIC6191中文资料Single Channel Bare-Bone USB Switch数据手册AIC规格书

描述 Description

The AIC6191 is an integrated 170mOhm high-side power switch, the preferred circuit protection method for computer, consumer, multimedia and portable applications. AIC6191 can protect sensitive electronics from damage caused by both overcurrent and overtemperature events.

The protection includes current limiting with foldback, short circuit and thermal shutdown under overcurrent occurs.

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.
