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 Swapв„ў controller is a good match for вЂ“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 ofп¬Ѓce telecom environments.
PICMG 3.0 deп¬Ѓnes, 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 LTC4252AвЂ™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 вЂ“48V dual battery
feed typical of telecom installations, and ATCA borrows
many of its related speciп¬Ѓcations from established
telecom standards. Over and undervoltage monitoring are both implemented
in this circuit. UV thresholds are set at вЂ“37V turning on …
