Overvoltage threshold
An overvoltage detector on the VDD pin allows the VIPer22A 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.
