Slow Turn ON and Fast Turn OFF.
Enable Active-High or Active-Low.
DESCRIPTION
The AIC1526 is a dual high-side power switch
for self-powered and bus-powered Universal
Serial Bus (USB) applications. One high-side
switch is a MOSFET with 110mΩ R
DS(ON)
, which
meets USB voltage drop requirements for
maximum transmission wire length.

Guaranteed minimum output rise time limits
inrush current during hot plug-in, minimizing
