 APPLICATIONS
 USB Power Management.
 Notebook PCs
 Battery-Charger Circuit.
The AIC6186 integrates dual 85m high-side
power switches for self-powered and
bus-powered Universal Serial Bus (USB)
applications. It operates with inputs ranging
from 2.7V to 6.5V, making it ideal for both 3 V
and 5V systems.
The protection includes current limiting with
fold-back, short circuit and thermal shutdown
under over-current occurs. Fault current is
limited to typically 0.65A in accordance with the
USB power requirements. The AIC6186 is
ideal for any system where current limiting and
power control are desired.
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.
