Abstract:
A flexible voltage transient detector circuit, comprisingan initialization unit, wherein the output (INIT) of said initialization unit decides the operational modes of an integrated circuit;a first comparator, comprising an output terminal connected to an input terminal of the initialization unit so that the output of said first comparator can reset said initialization unit, a noninverting input terminal connected to a first reference voltage, and an inverting input terminal connected to a power supply for comparing the power voltage with the first reference voltage; anda second comparator, comprising an output terminal connected to second input terminal of the initialization unit so that the output of said comparator can start the counting of said initialization unit, an inverting input terminal connected to a second reference voltage, and a noninverting input terminal connected to said power supply for comparing the power voltage with the second reference voltage.
