Figure 13. High Level Block Diagram Implementation for a PCI Hot Plug Slot
Although the primary application for the SMH4042 is as a
voltage controller for
CompactPCI
or VME boards, it is
versatile enough to be used as a Hot Plug controller on a
host PCI card. The functional blocks are similar to those
of the
CompactPCI
implementation but they are now
resident on the motherboard. The same circuits shown for
switching the voltages on the card can also be used for
controlling the slot voltages.
