Abstract
An integrated circuit (IC) includes subcircuits, power switches coupled to pass load current to a respective one of the subcircuits when activated by a respective switch control signal, and sensing circuits. Each of the sensing circuits is coupled to a respective one of the subcircuits, wherein the sensing circuits are configured to generate sense currents that are proportional to the respective load currents. The IC also includes a conversion circuit configured to receive at least one of the sense currents and to convert the at least one of the sense currents to an equivalent multi-bit digital signal, a timestamp circuit configured to generate a timestamp value that is correlated with the multi-bit digital signal, and a controller configured to provide signals to operate the power switches and the sensing circuits.
