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.  
o Monitor Four Power-Supply Voltages  
o Precision Factory-Set Threshold Options for 5.0V,  
3.3V, 3.0V, 2.5V, and 1.8V (Nominal) Supplies  
o Adjustable Voltage Threshold Monitors Down to  
0.62V  
o High-Accuracy ( 2.0ꢀ) Adjustable Threshold  
Inputs  
o Low Supply Current  
MAX6709: 35µA  
The MAX6709 provides four independent open-drain  
outputs with 10µA internal pullup to V . The MAX6714  
CC  
provides an active-low, open-drain RESET output with  
integrated reset timing and three power-fail comparator  
outputs.  
MAX6714: 60µA  
o Four Independent, Active-Low, Open-Drain  
Outputs with 10µA Internal Pullup to V  
CC  
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.  
o 140ms (min) Reset Timeout Period  
(MAX6714 only)  
o 2.0V to 5.5V Supply Voltage Range  
o Immune to Supply Transients  
o Fully Specified from -40°C to +85°C  
o 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-  
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  
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.
