FEATURES  
DESCRIPTIO  
TheLTC®4244/LTC4244-1areHotSwapTM controllersthat  
allow a board to be safely inserted into and removed from  
a CompactPCITM bus slot. External N-channel transistors  
control the 5V and 3.3V supplies while on-chip switches

be ramped up at an adjustable rate. Electronic circuit  
breakers protect all four supplies against overcurrent  
faults.Afterthepower-upcycleiscomplete,theTIMERpin  
capacitor serves as auxiliary VCC allowing the LTC4244/  
LTC4244-1 to function without interruption in the pres-  
ence of voltage spikes on the 12VIN supply. The PWRGD  
output indicates when all four supplies are within toler-  
ance. TheOFF/ONpinisusedtocycleboardpowerorreset  
the circuit breaker. The PRECHARGE output can be used  
to bias the bus I/O pins during card insertion and extrac-  
tion. PCI_RST# is combined on-chip with HEALTHY# in  
order to generate LOCAL_PCI_RST#.
