Description

General part information

LTC4241 Series

The LTC4241 is a Hot Swap controller that allows a board to be safely inserted and removed from a live PCI-bus slot. It has a primary controller that controls the four PCI supplies and an independent auxiliary controller to control the 3.3V auxiliary supply. External N-channel transistors are used to control the 3.3V, 5V and 3.3V auxiliary supplies while on-chip switches control the –12V and 12V supplies. The 3.3V, 5V and 3.3V auxiliary supplies can be ramped up at an adjustable rate. Electronic circuit breakers protect all five supplies against overcurrent faults. The foldback current limit feature reduces current spikes and power dissipation when shorts occur. ThePWRGDoutput of the primary controller indicates when all four PCI supplies are within tolerance. TheFAULToutput indicates an overcurrent condition for any of the five supplies.The LTC4241 is available in the 20-pin narrow SSOP package.ApplicationsPCI-Based ServersComputer Systems
