To check the reset circuit ,the reset output is low to discharge the delay capacitor(=Cd). if it’s less than VO1-0.25V. And the reset output is high when the delay capacitor voltage linearly increased by the interal current source(10µA) if it’s more than VO1- 0.2V. The equations of delay time is same as below. Trd = (Cd X 2.5) / 10µA 4 2. Although guaranteed, these parameters are not 100% tested in production.
