Abstract
A voltage detector comprises an input, a resistor divider circuit having resistors coupled in series with one another between the input and a reference node, and N intermediate nodes joining adjacent pairs of the resistors. The voltage detector has N switches coupled to the respective intermediate nodes, as well as a comparator with an input coupled to the switches, a state machine having an input coupled to the output of the comparator, and a decoder having N decoder outputs coupled to respective control terminals of the N switches.
