  Low Voltage Hot Swap Controller Ignores Backplane Noise
  and Surges – Design Note 319
  Mitchell Lee
  First generation single supply Hot Swapв„ў controllers,
  such as the LTC В®1422, combine the features of various
  discrete inrush limiting circuits into a single IC, including
  an electronic circuit breaker, adjustable power-up rate,
  reset output, high side MOSFET gate drive, undervoltage
  lockout and a wide operating voltage range. The LTC4211
  advances these features by adding a dual level, dual
  response time electronic circuit breaker, adjustable softstart with inrush current limiting, fault detection, faster
  response time to severe overloads and operation from
  2.5V to 16.5V—all in a small 10-lead MSOP package.
  Control 25W with a 10-Lead MS Package
  Figure 1 shows a 5V, 5A Hot Swap application designed
  for inclusion on a removable circuit board. As is customary, the circuit board ground and VCC planes are wired
  to long connector pins, eliminating reliability problems
  associated with pin-to-receptacle arcing. Until the PC
  board is п¬Ѓrmly seated in the backplane, the MOSFET
  switch remains safely off and isolates CLOAD (typically
  100ОјF or more) from the backplane. Once the connector
  is fully seated, the R1-R2 divider which serves both as a
  connection sense and an undervoltage lockout, activates …
