  AdvancedTCA Hot Swap Controller Eases Power Distribution
  Design Note 353
  Mitchell Lee
  highly desirable to sanitize the incoming battery feeds
  and minimize power plane disturbances. The LTCВ®4252A
  Hot Swap™ controller is a good match for –48V, 0W
  to 200W applications. Introduction
  AdvancedTCA is a new modular computing architecture
  developed by the PCI Industrial Computer Manufacturers
  Group for use in central office telecom environments.
  PICMG 3.0 defines, among other things, the electrical
  and mechanical attributes of the backplane, connectors
  and removable cards in these systems. Circuit Solutions
  Figure 1 shows a complete circuit designed to handle
  up to the maximum available power. The LTC4252A’s
  accurate current limit is set to provide at least 5.5A
  under all conditions, a comfortable margin for 200W,
  yet trips off just under 7A to preserve fuse integrity in
  the presence of nuisance overloads. System power is supplied by the –48V dual battery
  feed typical of telecom installations, and ATCA borrows
  many of its related specifications from established
  telecom standards. Over and undervoltage monitoring are both implemented
  in this circuit. UV thresholds are set at –37V turning on …
