APPLICATIU
The LTC
1643 is a Hot Swap
TM
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. All supply voltages can be ramped up at a program-
mable rate. An electronic circuit breaker protects all four
supplies against overcurrent faults. The foldback current limit
feature limits current spikes and power dissipation when
shorts occur and allows boards with large capacitances to be
powered up without tripping the circuit breaker. The PWRGD
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.
