The MAX6800/MAX6801/MAX6802 microprocessor (μP)supervisory circuits monitor the power supplies in 2.85Vto 5.0V μP and digital systems. They increase circuitreliability and reduce cost by eliminaTIng external componentsand adjustments.
These devices perform a single funcTIon—they assert areset signal whenever the VCC supply voltage declinesbelow a preset threshold, keeping it asserted for a presetTImeout period after VCC has risen above the resetthreshold. The only difference among the three devicesis their output. The MAX6801 (push/pull) and MAX6802(open-drain) have an acTIve-low RESET output, while theMAX6800 (push/pull) has an active-high RESET output.The MAX6800/MAX6801 are guaranteed to be in the correctstate for VCC down to 0.7V. The MAX6802 is guaranteedto be in the correct state for VCC down to 1.0V.
