3 / 6 page KA7630/KA7631 3 Electrical Characteristics(KA7631) (Continued) (Refer to test circuit Vin1=7.5V ,Vin2=11.5V ,Tj = +25 °C, unless otherwise specified) Notes: 1. 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 internal current source(10 µA) if it’s more than Vo1- 0.2V. The equation of delay time is same as below. Trd = (Cd × 2.5) / 10 µA 2. These parameters, although guaranteed, are not 100% tested in production. Parameter Symbol Conditions Min. Typ. Max.
