When VHV crosses the VHV(start) threshold, the controller
can start immediately. When it crosses VHV(stop), it triggers
a timer of duration tHV: this ensures that the controller
doesn’t stop in case of line cycle drop−out.

The same scheme is used for the Line OVP, except that this
time the controller must not stop instantaneously when the
input voltage goes above VHV(OV1). In order to be
insensitive to spikes and voltage surges a blanking circuit is
inserted after the output of the comparator, with a duration
of tOV(blank).
