DESIGN FEATURES CompactPCI Hot Swap Controller with
I2C Interface, Bus Precharge and OnChip LOCAL_PCI_RESET# Logic
by Victor Fleury
Introduction When a board is plugged into the
live backplane of a host system (hot
swapped), the bulk bypass capacitors
of the board can draw large inrush
currents as they charge. These transient currents can damage connectors
or create glitches on the backplane,
potentially causing other boards in
the system to inadvertently reset. To
prevent such large inrush currents, the
bulk bypass capacitors on the plug-in
board must be isolated during the Hot
Swap sequence.
The LTC4240 provides a controlled
on-off switch for four hot swappable
board power supply voltages, allowing the board to be safely inserted
or removed from a live CompactPCI
(CPCI) slot without disturbing the
system power supplies. The LTC4240
includes an I2C-compatible interface
that allows software control and moniCompactPCI …
