MAX6345ZUT-T

Overview

The MAX6345ZUT-T is a voltage supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.2V to 5.5V and features a single monitored input with a fixed threshold voltage of 2.93V. The device provides an active-low, open-drain reset output and includes a manual reset input for system control. It incorporates a typical reset delay time of 200ms to ensure stable power-up sequencing. The component is available in a compact SOT-23-6 package and supports operation across commercial and industrial temperature ranges.

Feature Summary

• Provides precise voltage supervision with a fixed threshold for reliable power monitoring
• Includes a manual reset input allowing external control over the reset state
• Features an active-low open-drain output compatible with various logic families

Applications

• Portable equipment requiring low-voltage monitoring
• Battery-powered systems needing power-fail detection
• Microcontroller-based designs requiring stable power-up sequences

Procurement Notes

Verify the exact suffix against official documentation to confirm pinout and threshold specifications. Confirm RoHS compliance status and manufacturing origin through authorized channels. Ensure the supplier provides valid traceability records. Check for obsolescence notices or lifecycle changes prior to procurement. Validate that the component matches the required thermal and electrical ratings for the target application environment.

Selection Notes

Select this component when a fixed threshold voltage near 2.93V is required for single-supply monitoring. Consider the manual reset feature if external system control over the reset state is necessary. Evaluate the SOT-23-6 package size constraints against available board space. Verify that the operating temperature range meets the environmental requirements of the deployment site.

Part Context

This part belongs to the MAX6345 series of voltage supervisors designed for low-power applications. It is engineered to monitor a single voltage rail and generate a reset signal upon detecting out-of-range conditions. The series is characterized by low quiescent current and high accuracy, making it suitable for battery-operated devices where power efficiency is critical.

Replacement Considerations

Consult official substitution guides for equivalent parts with matching thresholds and packages. Verify compatibility of manual reset functionality and output drive capabilities before replacement.
