Overvoltage threshold VIPER12A-E

8 Overvoltage threshold
An overvoltage detector on the V
DD
pin allows the VIPER12A to reset itself when V
DD
exceeds V
DDovp
. 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 V
DD
to reach
V
DDoff
, and then the device resumes normal operation automatically.
