V CC powers the MAX6700/MAX6710Q and is not a
monitored voltage. IN2 powers all other options for the
MAX6710 and is a monitored voltage. When any supply
drops below its threshold, the reset output asserts low
and remains low while either IN1 or IN2 is above 1.0V.
Adjustable Thresholds
The MAX6700/MAX6710 offer several monitor options
with adjustable reset thresholds. The threshold voltage at
each adjustable IN_ input is typically 0.62V. To monitor a
voltage > 0.62V, connect a resistor-divider network to the
circuit as shown in Figure 5.
Figure 3. RESET Output Timing Diagram
V INTH = 0.62V x (R1 + R2) / R2
or, solved in terms of R1:
IN2 = +3.3V
+5V
R1 = R2 ((V INTH / 0.62V) - 1)
Because the MAX6700/MAX6710 have a guaranteed

input current of ±0.2μA (±0.4μA for IN1) on their
adjustable inputs, resistor values up to 100k ? can be
used for R2 with < 1% error. The MAX6700/MAX6710Q

include an internal voltage clamp (1.5V typ) at each of
the adjustable voltage inputs. An input voltage higher
than 1.5V induces a higher input current.
Unused Inputs
Connect unused monitor inputs to a supply voltage
greater in magnitude than their specified threshold volt-
ages. For unused IN_ adjustable inputs, connect a 1M ?
series resistor between the unused input and IN2 (or
V CC ) to limit the bias current. Use IN2 for normal opera-
tion (device power-supply pin). Do not connect unused

monitor inputs to ground or allow them to float.
Adding Manual Reset Capability
(MAX6710)
Figure 6 shows an application circuit adding manual reset
to the MAX6710. Depressing the pushbutton switch short-
circuits the analog input to ground and initiates a RESET
pulse. The switch must be open for at least 140ms in
order to deassert the RESET output. No external switch
debounce is required. Use a small capacitor to improve
noise immunity when using long leads from the pushbut-
ton switch to the adjustable input.

Figure 5. Setting the Auxiliary Monitor
V INTH
The MAX6700/MAX6710 are normally powered from the
monitored IN2 or from the V CC supply input. All monitored
inputs are immune to short supply transients. For higher
immunity in noisy applications, connect a 0.1μF bypass
capacitor from the IN2 input to ground. Add capacitance
to IN1, IN3, and IN4 to increase their noise immunity.
