The MIC2580 is a hot-swap controller that provides for safeand orderly insertion and removal of PCI based adapter cardsfrom a PCI hot-plug compliant system backplane orCompactPCI™ system.The MIC2580 incorporates a circuit breaker function thatprotects all four supplies (+12V, +5V, +3.3V, and –12V) uponan overcurrent fault condition. Current foldback limiting preventslarge transient currents caused by plugging adaptercards into live backplanes, such as in a CompactPCI system.A programmable slew-rate control limits high inrush currentsto all loads that occur when power is applied to large capacitiveloads.Voltage supervisory functions for all four power supplies areprovided by “power good” (/PWRGD) and “overcurrent fault”(/FAULT) diagnostic outputs. Power good and overcurrentfault include deglitch filters to prevent nuisance tripping.Power good is active when all four supplies are withintolerance. Fault (/FAULT) goes active upon overcurrent orovertemperature conditions. The on-off control input (/ON) isused to cycle power to the adapter card.
