The LTC
4260 Hot Swap
TM
controller allows a board to be
safely inserted and removed from a live backplane. Using
an external N-channel pass transistor, the board supply
voltage can be ramped up at an adjustable rate. An I
2
C
interface and onboard ADC allow monitoring of board
current, voltage and fault status.
The device features adjustable analog foldback current
limit with latch off or automatic restart after the LTC4260
remains in current limit beyond an adjustable time-out
delay.
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.
