Overvoltage threshold

VIPER12A-E

An overvoltage detector on the VDD pin allows the VIPER12A to reset itself when VDD

exceeds VDDovp. This is illustrated in Figure 8., which shows the whole sequence of an

overvoltage event. Note that this event is only latched for the time needed by VDD to reach

VDDoff, and then the device resumes normal operation automatically.
