Low-Voltage, High-Accuracy, Quad Voltage

Monitors in µMAX Package

General Description

Features

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.

♦ Monitor Four Power-Supply Voltages

♦ Precision Factory-Set Threshold Options for 5.0V,

3.3V, 3.0V, 2.5V, and 1.8V (Nominal) Supplies

♦ Adjustable Voltage Threshold Monitors Down to

0.62V

♦ High-Accuracy ( 2.0ꢀ) Adjustable Threshold

Inputs

♦ Low Supply Current

MAX6709: 35µA

The MAX6709 provides four independent open-drain

outputs with 10µA internal pullup to V . The MAX6714

provides an active-low, open-drain RESET output with

integrated reset timing and three power-fail comparator

outputs.

MAX6714: 60µA

♦ Four Independent, Active-Low, Open-Drain

Outputs with 10µA Internal Pullup to V

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.

♦ 140ms (min) Reset Timeout Period

(MAX6714 only)

♦ 2.0V to 5.5V Supply Voltage Range

♦ Immune to Supply Transients

♦ Fully Specified from -40°C to +85°C

♦ Small 10-Pin µMAX Package

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-

Ordering Information

out circuit forces all four digital outputs low when V

drops below the minimum operating voltage. The four

digital outputs have weak internal pullups to V

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.
