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 signal and an output for outputting a detection signal, wherein the first voltage detector is configured to output the detection signal when the voltage of the input signal meets a first rising input voltage threshold; a second voltage detector having an input for receiving the input signal and an output for outputting a detection signal, wherein the second voltage detector is configured to output the detection signal when the voltage of the input signal meets a second rising input voltage threshold which is higher than the first threshold, wherein the output of the second voltage detector controls a connection between the input signal and the input of the first voltage detector such that when the voltage the input signal meets the second rising input voltage threshold the connection between the input and the input of the first voltage detector is inhibited or disconnected.
