Overvoltage threshold
An overvoltage detector on the V pin allows the VIPer22A to reset itself when V
DD
DD
exceeds V
. This is illustrated in Figure 8. which shows the whole sequence of an
DDovp
overvoltage event. Note that this event is only latched for the time needed by V to reach
DD
V
, and then the device resumes normal operation automatically.
