摘要： This document discusses, among other things, apparatus and methods for providing a power-on-reset signal. An example apparatus can include a regulator configured to receive a supply voltage and to provide a regulated voltage at an output, and a power-on-reset (POR) circuit including a POR comparator. The POR circuit can be configured to provide an indication that the regulated voltage is below a threshold level using an output of the POR comparator and to disable the POR comparator when the regulated voltage is above the threshold level.

摘要： An apparatus comprises an input to receive a voltage, a threshold voltage circuit, a comparison circuit, and an output. The threshold voltage circuit provides an adjustable first threshold voltage at a first output and an adjustable second threshold voltage at a second output. The comparison circuit determines when the input voltage is greater than the first voltage threshold, including when the first voltage threshold is adjusted substantially up to a high supply voltage rail, and determines when the input voltage is less than the second voltage threshold, including when the second voltage threshold is adjusted substantially down to a low supply voltage rail. The output provides a first indication when the input voltage is greater than the first voltage threshold and to provide a second indication when the input voltage is less than the second voltage threshold.
