The LTC
1647-1/LTC1647-2/LTC1647-3 are dual Hot
Swap
TM
controllers that permit a board to be safely in-
serted and removed from a live backplane.
Using external N-channel MOSFETs, the board supply
voltages can be ramped up at a programmable rate. A high
side switch driver controls the MOSFET gates for supply
voltages ranging from 2.7V to 16.5V. A programmable
electronic circuit breaker protects against overloads and
shorts. The ON pins are used to control board power or
clear a fault.
The LTC1647-1 is a dual Hot Swap controller with a
common V
CC
pin, separate ON pins and is available in an
SO-8 package. The LTC1647-2 is similar to the LTC1647-1
but combines a fault status flag with automatic retry at the
ON pins and is also available in the SO-8 package. The
LTC1647-3 has individual V
CC
pins, ON pins and FAULT
status pins for each channel and is available in a 16-lead
narrow SSOP package.
