Abstract

PURPOSE:To generate a reset output surely even at momentary power failure, by giving a different conduction time to the 1st and 2nd switching transistors (TRs). CONSTITUTION:When a voltage between input lines 1 and 2 rises from a lower voltage value than an operating voltage of a Zener diode 17, a switching TR12 conducts without fail before a switching TR11 conducts. Thus, when an input voltage Vi changes as shown in (a), an output voltage V0, a collector voltage Vc of the TR11, and a reset output voltage Vr also change as shwon in (b), (c) and (d), allowing to generate a reset output surely at any of times t1, t3 and t6.
