MAX6337US17D3+

Overview

The MAX6337US17D3+T is a 4-pin, ultra-low-voltage, low-power microprocessor reset circuit manufactured by Analog Devices Inc./Maxim Integrated. It features a manual reset input and an active-low, open-drain output. The device monitors a single voltage input with a threshold of 1.7V. Operating supply voltage ranges from 1V to 5.5V. Reset delay time is 100ms minimum. Accuracy is 1.8%. Operating temperature range is -40°C to +125°C (TA). Supply current is 3.3uA typical. Package is SOT-143-4.

Feature Summary

• Monitors system voltage and asserts a reset signal when the supply declines below a preset threshold or upon manual activation.

Applications

• Microprocessor and digital systems requiring power supply supervision

Procurement Notes

Verify the specific suffix 'D3+' against official Analog Devices documentation to confirm pinout configuration and lead-free status. Ensure the ordering part number matches the exact threshold voltage variant required for the application design. Cross-reference the manufacturer's latest datasheet revision to confirm current manufacturing status and any potential obsolescence notices prior to procurement.

Selection Notes

Select this component for applications requiring precise voltage monitoring in low-power environments. The fixed 1.7V threshold suits 1.8V logic systems. Consider the SOT-143 package size for space-constrained designs. Verify that the open-drain output capability aligns with the target system's reset input requirements.

Part Context

Part of the MAX6335/MAX6336/MAX6337 family of microprocessor supervisory circuits designed for 1.8V to 3.3V systems. These devices eliminate external components and adjustments, increasing reliability while reducing cost through integrated threshold detection and manual reset functionality.

Replacement Considerations

Consult Analog Devices official substitution guides for direct replacements. Generic equivalents may not match the specific 1.7V threshold or low-power characteristics.
