ABSTRACT:
A resetting circuit for microprocessors which facilitates the operation of a microprocessor even with extensively disrupted supply voltages. For this purpose, in a voltage stabilization circuit for supplying a microprocessor there is monitored the voltage difference between the supply voltage and the operating voltage through a potential difference-controlled flip-flop. This flip-flop generates a resetting signal when the supply voltage has approached its minimum permissible value, in effect, is therebelow. Upon the subsequent rise of the supply voltage, the resetting signal is maintained until there is again reached a predeterminable percentage of the rated value of the supply voltage.
