Low-Voltage, High-Accuracy, Quad Voltage
Monitors in 碌MAX Package
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 10碌A(chǔ) internal pullup to V
CC
. The MAX6714
provides an active-low, open-drain
RESET
output 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 35碌A(chǔ) (typ) of supply cur-
rent. The MAX6714 consumes only 60碌A(chǔ) (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 V
CC
drops below the minimum operating voltage. The four
digital outputs have weak internal pullups to V
CC
,
accommodating wire-ORed connections. Each input
threshold voltage has an independent output. The
MAX6709/MAX6714 are available in a 10-pin 碌MAX
package and operate over the extended (-40擄C to
+85擄C) temperature range.
