Abstract
A method of operating a power up circuit is disclosed. The method includes receiving an input voltage and creating a plurality of sample voltages from the input voltage. One of the sample voltages is selected and compared to a reference voltage. The power up circuit produces a brown-out signal in response to the step of comparing.
