Hot-swapping is now a standard feature for many plug-in boards; implementing it requires understanding power-management circuits and components. There is always more that can be added to ensure proper and reliable performance under arduous and mission-critical conditions. Q: What further can be done to ensure safe performance and no damage to the board being swapped? […]

FAQ on Hot Swap: from “don’t dare do it” to “it’s now OK to do” part 2
Designing a hot-swap controller is not trivial, as there are many conditions that must be acknowledged and addressed. The problem is aggravated by the increasing power and current levels of many of today’s boards — both are increasing dramatically — which puts severe current-handling and thermal strain on the current-pass MOSFET, which the high-level view […]
FAQ on Hot Swap: from “don’t dare do it” to “it’s now OK to do” part 1
It wasn’t that long ago that one of the strict rules when assembling a system or debugging it was simple: don’t plug or unplug anything — component, cable, board — with the power on. You were firmly instructed to shut off the power and only turn it back on when you were done with connecting […]
