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 110mW 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 1A,
well below the 5A safety requirement, and the
thermal shutdown function independently
controls each channel under overcurrent
condition.
Guaranteed minimum output rise time limits
inrush current during hot plug-in, minimizing
EMI and preventing the voltage at upstream port
from dropping excessively.
