MAX6319LHUK44C-T

Supervisors Overview

The MAX6319LHUK44C-T is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of up to 5.5 V and features a fixed threshold voltage of 4.39 V with an overvoltage threshold of 4.487 V. The device provides a reset delay time of 1.4 ms and maintains an accuracy of 1.5%. It consumes a typical operating supply current of 3 uA. The component supports manual reset functionality and offers active high, active low, or push-pull output types. It is housed in a SOT-23-5 package and functions across a temperature range from -40 C to +125 C.

Supervisors Feature Summary

• Provides precise voltage supervision with fixed threshold detection for system reliability.
• Integrates manual reset input capability for controlled system initialization.
• Delivers flexible output configurations including active high, active low, and push-pull modes.
• Ensures stable operation across extended industrial temperature ranges.

Supervisors Applications

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

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status as specifications may vary by production batch. Check lead times carefully since availability can fluctuate based on manufacturing schedules. Ensure packaging integrity matches project requirements for surface mount assembly processes.

Supervisors Selection Notes

Select this part when a fixed 4.39 V threshold is required for single-channel voltage monitoring. Consider the 3 uA quiescent current for battery-sensitive designs. Verify that the SOT-23-5 package fits the PCB layout constraints. Ensure the 1.4 ms reset delay aligns with system startup timing requirements.

Supervisors Part Context

This component belongs to the MAX6319 series of microprocessor supervisors. It shares common family traits such as low power consumption and manual reset inputs with other variants in the line. However, specific threshold voltages and output configurations differ significantly between part numbers within the same series.

Supervisors Replacement Considerations

Direct substitutes include MAX6319LHUK44C+T and MAX6319LHUK44CW+T. These alternatives maintain identical electrical characteristics and pinout compatibility while potentially differing in tape-and-reel packaging options or regional distribution channels.
