Abstract
A voltage monitor circuit comprises: a monitored voltage input (); a reference capacitor () arranged to be able to store a value of the monitored voltage as a reference capacitor voltage; a timeout capacitor () arranged to be able to store a value of the monitored voltage as a timeout capacitor voltage. The timeout capacitor undergoes a higher leakage than the reference capacitor. The voltage monitor circuit also comprises a comparator () arranged to: compare the monitored voltage to the reference capacitor voltage; compare the timeout capacitor voltage to the reference capacitor voltage; and produce a logic signal on an output () of the comparator based on said comparisons, the logic signal having a first logic value at least if the reference capacitor voltage is lower than or equal to both the monitored voltage and the timeout capacitor voltage.
