Abstract
An apparatus including a printed circuit board (PCB) including a sense resistor; and an integrated circuit (IC) mounted on the PCB, wherein at least a portion of the IC draws current from a power rail, wherein the sense resistor is coupled between the power rail and the IC, wherein the sense resistor is configured to produce a sense voltage in response to the current drawn by the at least portion of the IC, and wherein the IC includes a current sensor configured to generate a signal indicative of the current drawn by the at least portion of the IC based on the sense voltage.
