35 mA, 2.0 V to 5.5 V, low-voltage, high-accuracy, quad voltage monitor
General Description
The MAX6709/MAX6714 quad voltage monitors provide
accurate monitoring of up to four supplies without any
external components. A variety of factory-trimmed thresh-
old voltages and supply tolerances are available to opti-
mize the MAX6709/MAX6714 for specific applications.
The selection includes input options for monitoring 5.0V,
3.3V, 3.0V, 2.5V, and 1.8V voltages. Additional high-input-
impedance comparator options can be used as
adjustable voltage monitors, general-purpose compara-
tors, or digital-level translators.
The MAX6709 provides four independent open-drain
outputs with 10µA internal pullup to VCC. The MAX6714
provides an active-low, open-drain RESEToutput with
integrated reset timing and three power-fail comparator
outputs.
Each of the monitored voltages is available with trip
thresholds to support power-supply tolerances of either
5% or 10% below the nominal voltage. An internal
bandgap reference ensures accurate trip thresholds
across the operating temperature range.
The MAX6709 consumes only 35µA (typ) of supply cur-
rent. The MAX6714 consumes only 60µA (typ) of supply
current. The MAX6709/MAX6714 operate with supply
voltages of 2.0V to 5.5V. An internal undervoltage lock-
out circuit forces all four digital outputs low when VCC
drops below the minimum operating voltage. The four
digital outputs have weak internal pullups to VCC,
accommodating wire-ORed connections. Each input
threshold voltage has an independent output. The
MAX6709/MAX6714 are available in a 10-pin µMAX
package and operate over the extended (-40°C to
+85°C) temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 1:
100% production tested at TA= +25°C. Overtemperature limits guaranteed by design.
Note 2:
Condition at VCC= 1V is guaranteed only from TA= 0°C to +70°C.
Note 3:
Monitored voltage 5V/3.3V is also the device supply. In the typical condition, supply current splits as follows: 25µA for the
resistor-divider, and the rest for other circuitry.

Detailed Description
The MAX6709/MAX6714 are low-power, quad voltage
monitors designed for multivoltage systems. Preset
voltage options for 5.0V, 3.3V, 3.0V, 2.5V, and 1.8V
make these quad monitors ideal for applications such
as telecommunications, desktop and notebook comput-
ers, high-end printers, data storage equipment, and
networking equipment.
The MAX6709/MAX6714 have an internally trimmed
threshold that minimizes or eliminates the need for
external components. The four open-drain outputs have
weak (10µA) internal pullups to VCC, allowing them to
interface easily with other logic devices. The weak inter-
nal pullups can be overdriven by external pullups to any
voltage from 0 to 5.5V. Internal circuitry prevents current
flow from the external pullup voltage to VCC. The out-
puts can be wire-ORed for a single power-good signal.
The MAX6709 quad voltage monitor includes an accu-
rate reference, four precision comparators, and a
series of internally trimmed resistor-divider networks to
set the factory-fixed threshold options. The resistor net-
works scale the specified IN_ reset voltages to match
the internal reference/comparator voltage. Adjustable
threshold options bypass the internal resistor networks
and connect directly to one of the comparator inputs
(an external resistor-divider network is required for
threshold matching). The MAX6709 monitors power
supplies with either 5% or 10% tolerance specifica-
tions, depending on the selected version. Additional
high-input-impedance comparator options can be used
