  DESIGN FEATURES Versatile Hot Swap Controller with
  Open Circuit Detect, Foldback
  Current Limiting and Much More
  by Mark Belch Introduction
  When a circuit board is inserted into
  a live backplane, the input capacitors
  on the board can draw high inrush
  currents from the backplane power
  bus as they charge. The inrush current
  can permanently damage the connector pins and board components as well
  as glitch the system supply, causing
  other boards in the system to reset.
  The new LT4254 provides a compact
  and robust solution to eliminate these
  hot plugging issues.
  The LT4254 is designed to turn
  on a board’s supply voltage in a controlled manner, allowing the board to
  be safely inserted or removed from a
  live backplane having a supply voltage
  from 10.8V to 36V. The device features
  programmable inrush current control,
  current foldback, programmable 1%
  tolerance on the undervoltage and …
