DESIGN FEATURES Hot Swapping the PCI Bus
Using the LTC1643
Hot Circuit Insertion LTC1643 Features When a circuit board is inserted into
a live PCI slot, the supply bypass
capacitors on the board can draw
huge transient currents from the PCI
power bus as they charge. The transient currents can cause permanent
damage to the connector pins and
create glitches on the power bus, causing other boards in the system to
reset.
The LTC1643 is designed to turn a
boardвЂ™s supply voltages on and off in
a controlled manner, allowing the
board to be safely inserted into or
removed from a live PCI slot without
causing glitches on the system power
supplies. The chip also protects the
PCI supplies from short circuits and
monitors the supply voltages.
The LTC1643H is designed for
motherboard applications, whereas
the LTC1643L is designed for CompactPCI applications where the chip
resides on the plug-in board. The part …
