  DESIGN FEATURES Hot Swap Controller with
  Power-Up Timeout Function
  Simplifies Hot Swapping Boards
  with Multiple Power Supplies
  by Anthony Ng and YK Sim Introduction
  The LTC4212 is a Hot Swap controller that allows safe board insertion
  and removal from a live backplane.
  It features a supply range of 2.5V to
  16.5V, programmable soft-start with
  inrush current limiting, automatic retry or latched mode operation, a high
  side drive for an external N-channel
  MOSFET and dual level overcurrent
  fault protection.
  Unlike many Hot Swap controllers,
  the LTC4212 does not monitor the load
  side of the MOSFET directly. Instead,
  the LTC4212 interfaces with external
  power supply monitor ICs or directly
  with the PGOOD pin of a switching
  regulator. This permits the LTC4212 to
  monitor any number of supplies on the
  board. It has a power-up timeout function that disconnects a card from the
  backplane supply when the monitored …

  DESIGN IDEAS Ramp Three Supplies with a Supply
  Monitor and Hot Swap Controller
  by Mitchell Lee
  Many digital systems with multiple
  supply voltages require simultaneous
  ramping of supplies at power up. Since
  the power supply usually consists of
  separate regulators for each voltage,
  it is impossible to guarantee simultaneity of output. The circuit shown in
  Figure 1 ramps the outputs of three
  supplies and ensures tracking at
  power up and during recovery from a
  fault.
  Regulators invariably start up at
  different rates and different times
  based on current capability, filter
  capacitance and loop characteristics,
  so there are no guarantees as to how
  or when the outputs will rise to their
  respective voltages. In this case, an
  LTC1728-2.5 triple supply monitor
  keeps watch over each of three regulated supplies (1.8V, 2.5V and 3.3V).
