An Easy Way to Add Auxiliary Control Functions to
Hot Swap Cards вЂ“ Design Note 421
Mark Thoren
Introduction
A Hot Swapв„ў controller is essential to any system in
which boards are inserted into a live backplane. The
controller must gently ramp up the supply voltage and
current into the cardвЂ™s bypass capacitors, thus minimizing disturbances on the backplane and to other cards.
Likewise, it must disconnect a faulty card from the
backplane if it draws too much current. The controller
also monitors undervoltage and overvoltage conditions
on the backplane supply, ensuring reliable operation of
the cardвЂ™s circuitry. The LTC4215-1 takes the obvious
next step and integrates three general purpose I/O (GPIO)
lines and an accurate ADC into the Hot Swap controller
to provide quantitative information on board voltage
and current. Upgrading to the LTC4215-1 is analogous
to replacing a carвЂ™s venerable вЂњCheck EngineвЂќ light with
a modern dashboard information display. RS

CONNECTOR 1 High availability systems are designed
to achieve an ideal of zero down time.
To approach this goal, the system
needs to be able to operate during routine maintenance and upgrades, which
often involves cards being inserted and
removed from a live backplane. These
systems must also be designed for
failsafe operation by isolating faulty
boards before they cause backplane
disturbances.
Hot swapping requires a power
switch to initially isolate the board,
and a controller to turn on the switch
slowly to minimize backplane disturbances. Since the Hot Swap controller
monitors card voltage and current, it
is an obvious place to integrate higher
level monitoring with a data converter.
This provides detailed information
about the health of the power path …
