Abstract
Electronic circuits and methods are provided for use in hot-swappable circuit board applications. Circuitry detects an electrical ground connection and signals operation of a hot-swap controller. Detection of stable operating power causes a hierarchical startup of plural voltage regulators. Sensing stable output power from the last of the voltage regulators triggers the configuration of one or more programmable devices. Circuitry and other resources of a hot-swappable circuit board are protected against electrical transient-related damage by virtue of the present teachings.
