4245 Hot Swap

controller allows a board to
be safely inserted and removed from a live backplane in
multiple supply systems such as CompactPCI and PCI
Express. Using four external N-channel pass transistors,
the board supply voltages can be ramped up at an adjust-
able rate and in any desired sequence. An I
2
C interface and
onboard ADC allow monitoring of board current, voltage
and fault status for each supply.
The device features adjustable dI/dt controlled soft start
and foldback limited inrush current. A dual-level timed
circuit breaker and fast current limit protect each supply
against overcurrent faults. A power good input with timeout
allows a downstream supply monitor to disconnect the
board supplies. The device can be con gured to function
without a 12V supply or with an extra 3.3V supply instead
of a 5V supply.
The controller has additional features to interrupt the host
when a fault has occurred, notify when output power is
good, detect insertion of a load card and power-up in
either the on or off state.
