ABSTRACT:
An apparatus and method for the protection of an electronic circuit against anomalies in a supplied power voltage where the apparatus includes: a reserve power source connected to the supplied power voltage for providing voltage to the electronic circuit for a predetermined amount of time after an anomaly has occurred in the supplied power voltage, a module control for maintaining selected data and control signals transmitted to the electronic circuit during occurrence of the anomaly, and a differential comparator connected to the supplied power voltage and to the reserve power source to produces a comparator control signal upon occurrence of the anomaly, the differential comparator providing the comparator control signal to the module control.
