ABSTRACT:
A microprocessor reset device comprising a first comparator which, when the input signal of the device falls below a first threshold, closes a switch controlling discharging of a condenser. A second comparator connected to the condenser enables the reset signal when its input signal, correlated with the voltage of the condenser, falls below a seond threshold. For enabling of the reset signal to be dependent on both the duration of the reduction in the input signal below the first threshold, as measured by the voltage present at the terminals of the condenser, as well as on the amount of reduction, the input signal of the second comparator consists of a linear combination of the input signal and the voltage of the condenser, effected by an adding element.
