Maxim Integrated MAX6718AUKSDD3+T Triple/Dual Low-Voltage SOT23 µP Supervisory Circuits

The Maxim Integrated MAX6718AUKSDD3+T is a highly reliable triple/dual low-voltage microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems with multiple supply voltages.

This component is particularly suitable for battery-powered equipment, such as portable computers, telecommunications systems, and handheld instruments. The MAX6718AUKSDD3+T ensures that the µP is only operational when the power supply voltages are within acceptable levels, thus safeguarding the system from uncertain behavior that could arise from inadequate power supply conditions.

The supervisory circuit features a combination of multiple voltage monitors, each with its own factory-set reset voltage thresholds. These monitors keep a check on the system and assert a reset to the µP whenever any of the monitored supply voltages fall below the respective threshold. The reset output remains asserted for a minimum reset timeout period after all voltages rise above their thresholds, ensuring the system has ample time to stabilize.

The MAX6718AUKSDD3+T is available in a small, 5-pin SOT23 package, making it an excellent choice for space-constrained applications. Its low supply current makes it an energy-efficient option for portable devices. Additionally, it operates over a wide temperature range of -40°C to +85°C, accommodating a variety of environmental conditions.

Key features of the MAX6718AUKSDD3+T include:

• Triple/Dual Voltage Monitoring
• Factory-Set Reset Voltage Thresholds
• Manual Reset Input
• Minimum Reset Timeout Period
• Low Supply Current
• Immune to Short VDD Transients
• Wide Operating Temperature Range
• Compact 5-Pin SOT23 Package

Overall, the MAX6718AUKSDD3+T from Maxim Integrated is a robust and efficient solution for voltage monitoring in multi-voltage systems, ensuring reliable operation and system integrity.
