DESCRIPTION
The AIC1529 is a quad high-side power switch
for self-powered and bus-powered Universal
Serial Bus (USB) applications. Both high-side
switches are MOSFET with 110mΩ R_DS(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 1.3A, 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.
