MAX6337US20D3-T

Overview

The MAX6337US20D3-T is a supervisory circuit featuring an ultra-low-voltage design and low-power consumption. It operates within a supply voltage range up to 5.5 V with a typical operating supply current of 3.3 uA. The device provides a manual reset function and utilizes an active low, open-drain output type. It includes a reset delay time of 100 ms and maintains an accuracy of 1.8%. The overvoltage threshold is specified at 2.04 V. Power dissipation is rated at 320 mW. The component is housed in a SOT-143-4 package and supports surface mount installation.

Feature Summary

• Ultra-low-voltage operation suitable for battery-powered applications
• Manual reset capability for system control
• Low power consumption with minimal operating supply current
• Active low open-drain output interface

Applications

• Portable electronic devices requiring voltage supervision
• Battery-operated systems needing low quiescent current
• Microprocessor reset circuits in compact form factors

Procurement Notes

Verify the exact suffix designation as the +T variant may differ from the -T version regarding manufacturing status or specifications. Confirm RoHS compliance details through official documentation. Ensure the SOT-143-4 package matches your PCB footprint requirements. Check for obsolescence notices as this specific part number may be discontinued.

Selection Notes

Select this component when a manual reset input is required alongside voltage monitoring. The 2.04 V threshold suits applications where the monitored rail drops below standard logic levels. Consider the 100 ms delay for stable startup conditions. The open-drain output allows for wired-OR configurations if needed. Verify temperature range compatibility for your specific environment.
