Abstract

An integrated circuit including a comparator having a first input to receive a reference voltage, a second input, and an output to provide an under-voltage indicator. Sense points are configured to provide a plurality of sense point voltages, each sense point providing a corresponding sense point voltage of the plurality of sense point voltages; and a minimum voltage tracking circuit configured to receive the plurality of sense point voltages and provide an output voltage which tracks whichever sense point voltage of the plurality of sense point voltages is currently a minimum sense point voltage. The comparator receives the output voltage at the second input and asserts the under-voltage indicator when the output voltage is below the reference voltage.
