Features and Benefits
The MAX6700/MAX6710 precision triple/quad voltage microprocessor (µP) supervisory circuits monitor up to four system-supply voltages and assert a single reset if any supply voltage drops below its preset threshold. These devices significantly reduce system size and component count while improving reliability compared to separate ICs or discrete components.
A variety of factory-trimmed threshold voltages are available to accommodate different supply voltages and tolerances with minimal external component requirements. The MAX6710 includes internally fixed options for monitoring 5.0V, 3.3V, 3.0V, 2.5V, and 1.8V supplies with -5% or -10% tolerances. The MAX6710 is also available with one to three adjustable threshold options to monitor voltages down to 0.62V. The MAX6700 monitors three voltages with adjustable thresholds down to 0.62V.
A single active-low output asserts when any monitored input falls below its associated threshold. The open-drain output has a weak internal pullup (10µA) to IN2. For the MAX6710, reset remains low for the reset timeout period (140ms min) after all voltages rise above the selected threshold. The MAX6700 acts as a voltage detector with a propagation delay of 5µs after all monitored voltages exceed their thresholds. The output remains valid as long as either IN2 or IN2 input voltage remains above 1V (MAX6710) or VCC is above 2V (MAX6700/MAX6710Q).
The MAX6700/MAX6710 are available in a small 6-pin SOT23 package and operate over the extended (-40°C to +85°C) temperature range.
