4245 Hot Swap

TM

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.
