2 / 8 page KA7632/KA7633 2 Absolute Maximum Ratings Electrical Characteristics(KA7632) (Refer to test circuit Vin1=6V ,Vin2=10.5V ,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 interal current source(10 µA) if it’s more than Vo1- 0.2V. The equations of delay time is same as below. Trd = (Cd × 2.5) / 10 µA 2. These parameters, although guaranteed, are not 100% tested in production.
