MAX6385XS16D3+T

Supervisors Overview

The MAX6385XS16D3+T is a single-channel microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of +1.8V to +5.0V and consumes only 3µA at +1.8V. The device features a factory-set reset threshold voltage of 1.63V with ±2.5% accuracy over the operating temperature range of -40°C to +125°C. It provides an active-high, push-pull reset output with a minimum reset timeout period of 280ms. The component is housed in a compact SC-70-4 surface-mount package.

Supervisors Feature Summary

• Monitors power-supply voltages from +1.8V to +5.0V while maintaining ultra-low supply current consumption.
• Provides a manual reset input for system control alongside automatic power-on reset functionality.
• Features a push-pull active-high reset output with precise threshold accuracy across the industrial temperature range.

Supervisors Applications

• Microprocessor (µP) supervisory circuits
• Battery-powered portable equipment
• Consumer electronics requiring low-power monitoring

Supervisors Procurement Notes

Verify the exact part number suffix against official Analog Devices documentation to confirm threshold voltage and package type. Confirm RoHS compliance status and lead-free designation as specified in the datasheet. Check current availability status through authorized distributors, as specific variants may have limited stock or obsolescence notices. Ensure the ordering information matches the required reset timeout and output polarity specifications for your design.

Supervisors Selection Notes

Select this component when a single-channel supervisor with an active-high output is required. The fixed 1.63V threshold suits applications monitoring 1.8V or 3.3V rails where precise timing is needed. Consider the SC-70-4 package for space-constrained designs. Verify that the 280ms timeout meets the system's startup requirements. Compare against other MAX6385 variants if different thresholds or active-low outputs are preferred.

Supervisors Part Context

This part belongs to the MAX6381–MAX6390 family of SC70/µDFN, single/dual low-voltage, low-power µP reset circuits. The 'XS' prefix indicates a specific threshold voltage variant, while 'D3' denotes the SC-70-4 package. The '+T' suffix typically signifies tape-and-reel packaging. This family is designed for applications requiring reliable power supervision with minimal quiescent current.
