The LTC
®
4240 is a Hot Swap
TM
controller that allows a board
to be safely inserted and removed from a live CompactPCI
bus slot. The LTC4240 has a built-in 2-wire I
2
C compatible
interface to allow software control and monitoring of
device function and power supply status. Two external
N-channel transistors control the 3.3V and 5V supplies,
while two internal switches control the –12V and 12V
supplies. Electronic circuit breakers protect all four supplies
against overcurrent faults. The PWRGD output indicates
when all of the supply voltages are within tolerance. The
OFF/ON pin is used to cycle the board power or reset the
circuit breaker. The I
2
C interface allows the user to turn the
device off or on, set RESETOUT, turn on the status LED
driver and ignore 12V, –12V faults. It also allows the user
to read the status of the FAULT, RESETIN, RESETOUT,
PWRGD, PRSNT1# and PRSNT2# pins. Under a fault
condition, the I
2
C interface can also be used to determine
which of the four supplies generated the fault. The LTC4240
is available in a 28-pin narrow SSOP package.
