Dual Slot Hot Swap
Controller for PCI Express
The LTC
?/DIV>
4242 Hot Swap
TM
controller allows safe board
insertion and removal for two independent slots on a PCI
Express backplane. External N-channel transistors control
the 12V and 3.3V supplies while integrated switches control
the 3.3V auxiliary supplies. Both 12V and 3.3V supplies
can be ramped up at an adjustable rate. Dual level circuit
breakers and fast active current limiting protect all supplies
against overcurrent faults.
A supply lter at the V
CC
pin allows the LTC4242 to endure
supply transients. The EN input detects the presence of a
card in the PCI Express slot. The FAULT and AUXFAULT
outputs alert the system of overcurrent conditions on the
main and auxiliary supplies, respectively. PGOOD and
AUXPGOOD outputs indicate proper main and auxiliary
supply outputs.
