Abstract: A method, apparatus, and device provide for the detection of the adequacy of the current sourcing capability of a power source. The current sourcing capability of the power source is dynamically detected by sampling comparison values obtained during one or more sampling sub-windows and determining a sample density of comparison values. In response to the sample density of comparison values crossing a selectable density threshold, an insufficient-supply indication is generated.
