  DESIGN FEATURES Versatile 80V Hot Swap Controllers
  Drive Large MOSFETs; Improve
  Accuracy and Foldback
  Current Limiting
  by Mark Belch
  Introduction
  Routine maintenance and upgrades to
  high reliability computing, networking
  and telecommunications systems require that new or replacement circuit
  boards be inserted into a powered
  48V(typical) bus. 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 LT4256
  family (LT4256-1 and LT4256-2) provides a compact and robust solution to
  eliminate these hot plugging issues.
  The LT4256 is designed to turn
  on a board’s supply voltage in a controlled manner, allowing the board to …
