DESCRIPTIO  
TheLTC®1643AisaHotSwapTM controllerthatallowsaboard  
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(LTC1643AH)/ON (LTC1643AL/  
LTC1643AL-1) pin is used to cycle the board power or reset  
the circuit breaker. The LTC1643AL-1 has the ±12V power  
good comparators disabled.
