MAX6700/MAX6710 Low-Voltage, High-Accuracy, Triple/Quad Voltage P Supervisory Circuits in SOT Package General Description Features The MAX6700/MAX6710 precision triple/quad voltage Monitor Up to Four Power-Supply Voltages microprocessor (P) supervisory circuits monitor up to Precision Factory-Set Reset Threshold Options for four system-supply voltages and assert a single reset 5.0V, 3.3V, 3.0V, 2.5V, and 1.8V Supplies if any supply voltage drops below its preset threshold. Adjustable Voltage Threshold Monitors Down to These devices significantly reduce system size and 0.62V with 1.5% Accuracy component count while improving reliability compared to separate ICs or discrete components. Low 35A Supply Current A variety of factory-trimmed threshold voltages are available Open-Drain RESET Output with 10A Internal Pullup to accommodate different supply voltages and tolerances with 5s Propagation Delay (MAX6700) minimal external component requirements. The MAX6710 140ms (min) Reset Timeout Period (MAX6710) includes internally fixed options for monitoring 5.0V, 3.3V, RESET Valid to IN1 = 1V or IN2 = 1V 3.0V, 2.5V, and 1.8V supplies with -5% or -10% tolerances. The MAX6710 is also available with one to three adjustable Immune to Short Monitored Supply Transients threshold options to monitor voltages down to 0.62V. The Guaranteed from -40C to +85C MAX6700 monitors three voltages with adjustable thresholds Small 6-Pin SOT23 Package down to 0.62V. A single active-low output asserts when any monitored Ordering Information input falls below its associated threshold. The open-drain PART TEMP RANGE PIN-PACKAGE output has a weak internal pullup (10A) to IN2. For the MAX6700UT-T -40C to +85C 6 SOT23-6 MAX6710, reset remains low for the reset timeout period (140ms min) after all voltages rise above the selected MAX6710 UT-T -40C to +85C 6 SOT23-6 threshold. The MAX6700 acts as a voltage detector with MAX6710FUT-T -40C to +105C 6 SOT23-6 a propagation delay of 5s after all monitored voltages MAX6710KUT-T -40C to +105C 6 SOT23-6 exceed their thresholds. The output remains valid as long as either IN2 or IN2 input voltage remains above 1V Insert the desired suffix letter from the Selector Guide into the blank to complete the part number.
