MAX6340UK29+T

Overview

The MAX6340UK29+T is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.5 V to 5.5 V and features a fixed threshold voltage of 2.5 V. The device provides an active low, open-drain output with a reset delay time of 4.375 ms. It does not include manual reset, watchdog timer, or battery backup switch functions. The component is housed in a SOT-23-5 package and supports surface mount installation.

Feature Summary

• Monitors power supply voltage levels for system integrity
• Generates reset signal upon detecting undervoltage conditions
• Provides active low open-drain output interface

Applications

• Microprocessor reset circuits
• Power supply monitoring systems
• Embedded controller supervision

Procurement Notes

Verify the exact suffix against official datasheets to confirm threshold voltage accuracy. Confirm RoHS compliance status through manufacturer documentation. Check current availability as distribution channels may indicate limited stock or discontinuation. Ensure the SOT-23-5 package matches your PCB footprint requirements before ordering.

Selection Notes

Select this component when a fixed 2.5 V threshold is required for single-supply monitoring. The open-drain output allows flexible interfacing with various logic families. Consider the 4.375 ms delay for appropriate system startup timing. Verify that no manual reset or watchdog functionality is needed for the specific application design.

Part Context

This part belongs to the MAX6340 series of microprocessor reset circuits. It is designed for low-power applications requiring reliable power supervision. The UK suffix indicates the SOT-23-5 package type. The +T suffix typically denotes tape and reel packaging for automated assembly processes.

Replacement Considerations

Consult official substitution guides for compatible parts with similar threshold voltages and package types. Verify electrical characteristics match the original design requirements. Ensure pinout compatibility if direct replacement is intended.
