Electrical Characteristics(KA7630)
(Refer to test circuit Vin1=7.5V ,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). it’s less than Vo1-0.25V. And the
2. These parameters, although guaranteed, are not 100% tested in production.

reset output is high when the delay capacitor voltage linearly increased by the internal current source(10 A) if it’s more than
Vo1- 0.2V. The equation of delay time is same as below. Trd = (Cd × 2.5) / 10 A
