Abstract: This application note describes an ultra-low power microprocessor reset generator that is capable of operating for decades from a single AA Lithium cell. Where continuous intermittent reset is desired, this relaxation-oscillator circuit can provide adjustable pulse width and reset period. Typical operation producing 100µs pulses each second requires only 1µA current from a 1.8-5.5V supply. Formulas are provided for calculation of component values for a wide range of pulse width and period.
