Hot-Plug Applications
Application circuit cards with a high in-rush current
potential can be limited by use of the AAT4626.
The AAT4626 has both slew rate limited turn on
characteristics and current limit controlled outputs,
which make it ideally suited for power port hot-plug
applications. A host power back plane or hot plug
receptacle may be sensitive to short duration high
power surges. The AAT4626 will turn on in a linear
ramping fashion and regulate the inrush current
with in the specified current limit for the device.
The error flag usually will not be effected during
application turn on since the 10ms fault flag blank-
ing time is intended for these types of events. If an
application turn on current surge exceeds 10ms, an
RC delay filter may be added to the Flag output to
prevent the system from receiving an error during
the start up sequence.
