TC1278/TC1279
3.2
The TC1278/TC1279 provides accurate V
ing and reset timing during power-up, power-down,
and brownout/sag conditions. Furthermore, it rejects
negative-going transients (glitches) on the power
supply line.
duration vs. maximum negative excursion (overdrive)
for glitch rejection. Any combination of duration and
overdrive that lays under the curve will not generate a
reset signal. Combinations above the curve are
detected as a brownout or power-down. Transient
immunity can be improved by adding a capacitor in
close proximity to the V
