Abstract
Embodiments relate to a power monitoring circuit. The power monitoring circuit includes a divider circuit that generates a reference voltage that is inversely proportional to a regulator voltage. Moreover, the power monitoring circuit includes an integrator that generates an integrator voltage by integrating one or more regulator currents. The power monitoring circuit additionally includes a comparator for comparing the output of the divider circuit and the output of the integrator. The comparator of the power monitoring circuit generates an output signal in response to the integrator voltage being larger than the reference voltage.
