  DESIGN FEATURES CompactPCI Hot Swap Controller with
  I2C Interface, Bus Precharge and OnChip LOCAL_PCI_RESET# Logic
  by Victor Fleury
  Introduction When a board is plugged into the
  live backplane of a host system (hot
  swapped), the bulk bypass capacitors
  of the board can draw large inrush
  currents as they charge. These transient currents can damage connectors
  or create glitches on the backplane,
  potentially causing other boards in
  the system to inadvertently reset. To
  prevent such large inrush currents, the
  bulk bypass capacitors on the plug-in
  board must be isolated during the Hot
  Swap sequence.
  The LTC4240 provides a controlled
  on-off switch for four hot swappable
  board power supply voltages, allowing the board to be safely inserted
  or removed from a live CompactPCI
  (CPCI) slot without disturbing the
  system power supplies. The LTC4240
  includes an I2C-compatible interface
  that allows software control and moniCompactPCI …
