DESCRIPTION
The AIC1527 is a quad high-side power switch for
self-powered and bus-powered Universal Serial
Bus (USB) applications. One high-side switch is a
MOSFET with 110m
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 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.
