MAX6343LUT+T

Overview

The MAX6343LUT+T is a supervisory voltage detector featuring an active-low, open-drain output. It operates within a supply voltage range of 1V to 5.5V with a specific threshold of 4.63V and an overvoltage threshold of 4.7V. The device draws 30µA operating supply current and provides a reset delay time of 180ms. It supports power fail detection and functions across a temperature range of -40°C to 125°C in a SOT-23-6 package.

Feature Summary

• Provides active-low open-drain reset signal generation based on monitored supply voltage levels
• Includes manual reset capability for system control flexibility
• Supports power fail detection functionality for critical system monitoring

Applications

Procurement Notes

Verify the complete part number including suffixes such as +T for tape-and-reel packaging configuration. Confirm that the manufacturer designation matches Analog Devices Inc. or Maxim Integrated to ensure component authenticity. Check datasheet revisions for any updates to electrical characteristics or pin configurations before integration into final designs.

Selection Notes

Select this component when an active-low open-drain output is required for microcontroller reset circuits. Consider the 4.63V threshold specifically for applications monitoring 5V or similar rail voltages. Evaluate the 30µA quiescent current against system power budget constraints. Ensure the SOT-23-6 package fits the available PCB footprint and thermal requirements.

Part Context

This component belongs to the MAX6343 series of supervisory switches and voltage detectors from Maxim Integrated. These devices are designed to monitor supply voltages and generate reset signals for digital systems. The series typically offers various threshold options and output polarities to suit different application requirements.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure replacement parts match the active-low open-drain output type and similar threshold specifications.
