MAX6700/MAX6710 Low-Voltage, High-Accuracy, Triple/Quad Voltage μP Supervisory Circuits in SOT Package General Description 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.
