MAX6345LUT+

Overview

The MAX6345LUT+T is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for monitoring power supply voltages in electronic systems. It features a single monitored input with an active-low open-drain output and includes a manual reset capability. The device operates within a supply voltage range up to 5.5V and maintains accuracy of 1.5%. It incorporates a watchdog timer and provides a reset delay time of 180 ms. The component functions reliably across an industrial temperature range from -40°C to +85°C and consumes a typical operating supply current of 20 µA.

Feature Summary

• Integrates a watchdog timer for system reliability
• Provides manual reset functionality via dedicated input
• Features active-low open-drain output structure

Applications

• Embedded system power supervision
• Microcontroller reset circuits
• Industrial control unit monitoring

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm availability status as distribution channels may list this part as discontinued or limited stock. Ensure the manufacturer designation matches Analog Devices Inc. or Maxim Integrated to guarantee authenticity. Cross-reference the full part number against official datasheets to confirm pinout compatibility before integration into designs.

Selection Notes

Select this component when a single-channel voltage monitor with integrated watchdog protection is required. The SOT-23-6 package suits space-constrained surface-mount applications. Consider the 180 ms reset delay and 1.5% threshold accuracy for timing-sensitive designs. Verify that the 5.5V maximum supply rating aligns with the target system's power rails.

Part Context

This part belongs to the MAX6345L series of supervisory circuits. It serves as a compact solution for detecting under-voltage conditions and managing system resets. The device is distinct from multi-channel monitors like the MAX6358, offering a focused single-input architecture optimized for cost and board area efficiency in standard digital logic environments.
