  Hot Swap Solution Meets AMC and MicroTCA Standards
  Design Note 437
  Vladimir Ostrerov
  Introduction
  The LTC В®4223 is a dual Hot Swapв„ў controller that meets
  the power requirements of the Micro Telecommunication
  Computing Architecture (MicroTCA) specification recently
  ratified by the PCI Industrial Computer Manufacturers
  Group (PICMG). The LTC4223 monitors 12V load current by sensing
  voltage across an external resistor and outputs a groundreferenced voltage (at the 12IMON pin) proportional to
  the load current. It also provides separate power-good
  outputs for the two supplies and a single, common fault
  output. Additional features include card detection and
  independent control of the two supplies. The LTC42231 latches off after a circuit breaker fault timeout expires
  while the LTC4223-2 provides automatic retry after a
  fault. A fault on the 12V supply shuts down only the 12V
  path, leaving the 3.3V auxiliary power available for system
  management functions. A fault on the 3.3V AUX supply
  shuts down both supplies. The LTC4223 includes an internal pass FET for the 3.3V
  auxiliary supply and a driver for an external N-channel
  pass FET for the 12V payload supply. Inrush current for
  both supplies is controlled: the auxiliary supply has a
  п¬Ѓxed 240mA active current limit and the 12V ramp rate …

  DESIGN FEATURES L Compact Hot Swap Solution Simplifies
  Advanced Mezzanine Card Design
  by Chew Lye Huat
  Introduction
  Advanced Mezzanine Cards (AdvancedMC) are 80W add-on modules
  that are central to the extensibility
  of MicroTCA and AdvancedTCA high
  availability systems. AdvancedTCA targets high capacity, high performance
  applications whereas MicroTCA serves
  smaller, cost-sensitive applications
  with less demanding requirements.
  Unlike other mezzanine modules,
  which are bolted on, AdvancedMC
  modules can be inserted into a live
  backplane improving serviceability
  and flexibility. The LTC4223 offers a compact and
  comprehensive Hot Swap solution for
  Advanced Mezzanine Cards, providing
  inrush control, overcurrent protection
  and supply monitoring. It detects
  board insertion and extraction, allowing the 12V and 3.3V auxiliary power
  supply to be delivered in a controlled
  manner without damaging the connector. The LTC4223 provides a current …
