Abstract
An electrical circuit includes a comparator that receives a first signal at a first input pin, where the first signal is indicative of a current drawn from a power supply unit (PSU) that delivers power to an electronic component. The comparator substantially simultaneously receives a second signal at a second input pin, where the second signal is indicative of a voltage provided by the PSU to the electronic component and is set to a predetermined threshold. An output of the comparator changes if a difference exists between the first signal and the second signal. The electrical circuit includes a variable gain amplifier that provides the first signal to the comparator, where a gain of the variable gain amplifier is set according to the predetermined threshold.
