Abstract
A voltage detector comprising: a first voltage reference generator for generating a first voltage reference signal; a second voltage reference generator for generating a second voltage reference signal, wherein the second voltage reference signal is higher than the first voltage reference signal; a trigger, powered by an input signal to the voltage detector, and having an input for receiving either the first or second voltage reference signal and an output for generating a detection signal; and a switch for selectively, connecting the input of the trigger to the first or second voltage reference signal, wherein the switch is operative to connect the input of the trigger to the first voltage reference signal when the detection signal output by the voltage detector is low and is operative to connect the input of the trigger to the second voltage reference signal when the detection signal output by the voltage detector is high, and a voltage detector system for monitoring an input signal and outputting a detection signal when a voltage of the input signal meets a first threshold, the voltage detector system comprising: a first voltage detector having an input for receiving the input s…
