  • Portable Application.
  • Digital televisions
  • Computer
  • Multimedia
  • Mobile Phones
DESCRIPTION
The AIC6198 is a dual high-side power switch for self-powered and bus-powered Universal Serial Bus (USB) applications. Both high-side switches are MOSFET with 170mOhm RDS(ON), which meets USB voltage drop requirements for maximum transmission wire length.
The protection includes current limiting with foldback, short circuit, soft start 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.
