3.13.7 Suppres-
sion of
Glitches
Periodical alternating between
A
overvoltage and normal operating
voltage with T< 50µs and overvolt-
age duration > 5µs leads to over-
voltage detection.
If the transition from undervoltage
to overvoltage is faster than the fil-
tering time tglitch, the filtering time
tglitch for overvoltage detection is
not started again. The same is
valid for reverse order.
