The AIC1518 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 110m Ω RDS(ON),
which meets USB voltage drop requirements for
maximum transmission wire length.
Multi-purpose open-drain fault flag output
indicates over-current limiting, thermal
shutdown, or undervoltage lockout for each
channel. Output current is typically limited to
1.25A, and the thermal shutdown functions of
the power switches independently control their
channel under overcurrent condition.
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.
