  DESIGN FEATURES Hot Swapping the PCI Bus
  Using the LTC1643
  Hot Circuit Insertion LTC1643 Features When a circuit board is inserted into
  a live PCI slot, the supply bypass
  capacitors on the board can draw
  huge transient currents from the PCI
  power bus as they charge. The transient currents can cause permanent
  damage to the connector pins and
  create glitches on the power bus, causing other boards in the system to
  reset.
  The LTC1643 is designed to turn a
  board’s supply voltages on and off in
  a controlled manner, allowing the
  board to be safely inserted into or
  removed from a live PCI slot without
  causing glitches on the system power
  supplies. The chip also protects the
  PCI supplies from short circuits and
  monitors the supply voltages.
  The LTC1643H is designed for
  motherboard applications, whereas
  the LTC1643L is designed for CompactPCI applications where the chip
  resides on the plug-in board. The part …
