Transient Rejection
The TC1278/TC1279 provides accurate V
CC
monitor-
ing and reset timing during power-up, power-down,
and brownout/sag conditions, and rejects negative-
going transients (glitches) on the power supply line.
Figure 3-5 shows the maximum transient 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
CC
pin of the TC1278/TC1279.
