MAX6720UTYDD3

Supervisors Overview

The MAX6720UTYDD3 is a triple ultra-low-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors three independent voltage rails within a compact SOT-23-6 surface-mount package. The device features adjustable threshold voltages ranging from 900 mV to 3.3 V for lower rails and 1.8 V to 5 V for higher rails, accommodating various logic families. It provides an active low push-pull reset output with a fixed 210 ms timeout delay. Designed for low-power applications, it operates with a quiescent current of 15 uA and supports a maximum supply voltage of 5.5 V across an extended temperature range.

Supervisors Feature Summary

• Triple-channel voltage supervision for monitoring multiple power rails simultaneously
• Adjustable threshold detection for flexible configuration across different voltage levels
• Active low push-pull reset output ensuring robust signal integrity
• Ultra-low quiescent current consumption optimized for battery-powered systems

Supervisors Applications

• Portable electronic devices requiring multi-rail power management
• Battery-operated consumer electronics with strict power constraints
• Industrial control systems utilizing low-voltage logic interfaces
• Embedded computing platforms needing reliable voltage supervision

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability restrictions. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Check for obsolescence notices or lifecycle changes as this series may have limited production support. Ensure packaging specifications match design integration needs.

Supervisors Selection Notes

Select this component when triple voltage monitoring is required in space-constrained designs. Compare against single-channel supervisors if fewer rails need oversight. Evaluate threshold adjustability ranges against target supply voltages to ensure adequate margin. Consider the 210 ms reset delay relative to system startup timing requirements and processor initialization sequences.

Supervisors Part Context

This part belongs to the Maxim Integrated MAX67xx family of ultra-low-voltage supervisors. These circuits are designed for portable and battery-powered applications where power efficiency is critical. The MAX6720 variant specifically addresses triple-supply monitoring needs, distinguishing itself from dual-channel counterparts like the MAX6716 or single-channel models within the same product line.
