The LTC1643 is a Hot SwapTM controller that allows a board
to be safely inserted and removed from a live PCI-Bus slot.
Two external N-channel transistors control the 3.3V and 5V
supplies while on-chip switches control the –12V and 12V
supplies.Allsupplyvoltagescanberampedupataprogram-
mable rate. An electronic circuit breaker protects all four
suppliesagainstovercurrentfaults.Thefoldbackcurrentlimit
feature limits current spikes and power dissipation when
shortsoccurandallowsboardswithlargecapacitancestobe
poweredupwithouttrippingthecircuitbreaker.ThePWRGD
output indicates when all of the supply voltages are within
tolerance and the FAULT output indicates an overcurrent
condition.The ON(LTC1643H)/ON (LTC1643L/LTC1643L-1)
pin is used to cycle the board power or reset the circuit
breaker. The LTC1643L-1 has the
±12V power good com-
parators disabled.
The LTC1643 is available in a 16-pin narrow SSOP package.
