s  Hot Board Insertion into CompactPCI Bus
The LTC
?/DIV>
4244/LTC4244-1 are Hot Swap
TM
 controllers that
allow a board to be safely inserted into and removed from
a CompactPCI
TM
 bus slot. External N-channel transistors
control the 5V and 3.3V supplies while on-chip switches
control the ?2V supplies. The 3.3V and 5V supplies can
be ramped up at an adjustable rate. Electronic circuit
breakers protect all four supplies against overcurrent
faults. After the power-up cycle is complete, the TIMER pin
capacitor serves as auxiliary V
CC
 allowing the LTC4244/
LTC4244-1 to function without interruption in the pres-
ence of voltage spikes on the 12V
IN
 supply. The PWRGD
output indicates when all four supplies are within toler-
ance. The OFF/ON pin is used to cycle board power or reset
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#.
