The
Typical Operating Characteristics
show the
Maximum Transient Duration vs. Reset Threshold
Overdrive for which reset pulses are
not
generated. The
graph shows the maximum pulse width that a negative-
going V
CC
transient may typically have without issuing a
reset signal. As the amplitude of the transient increases,
the maximum allowable pulse width decreases.
Ensuring a Valid Reset Output Down to
V
CC
= 0
When V
CC
falls below the minimum operating voltage,
push-pull structured reset sinking (or sourcing) capabil-
ities decrease dramatically. High-impedance CMOS-
logic inputs connected to the RESET/
RESET
pin can
drift to indeterminate voltages. This does not present a
problem in most cases, since most μPs and circuitry do
not operate at V
CC
below +1V. For MXD1810/
MXD1815 applications where
RESET
must be valid
down to V
CC
= 0, adding a pulldown resistor between
RESET
and GND removes stray leakage currents, hold-
ing
RESET
low (Figure 8). The pulldown resistor value is
not critical; 100k
is large enough not to load
RESET
and small enough to pull
RESET
low. For MXD1812/
