UNIT
TVSx_POWERGOO
D_DEGLITCH
Powergood deglitch time for both
rising and falling edges
VSx voltage must cross powergood
threshold and stay for at least this time to
change powergood output
state.Measured from VSx into or out of
powergood threshold, until PGx toggles,
for both rising and falling edges.
