MAX6344ZUT

Overview

The MAX6344ZUT is a microprocessor supervisory circuit from the MAX6342–MAX6345 family, manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of +1V to +5.5V and features a fixed reset threshold voltage of +4.38V. The device provides power-fail monitoring via a +1.25V threshold detector for low-battery detection or secondary supply monitoring. It utilizes a SOT-23-6 package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

Provides factory-trimmed reset threshold voltages to improve system reliability compared to discrete components.
Includes a dedicated power-fail comparator with a +1.25V threshold for low-battery or secondary supply monitoring.
Operates across a wide supply voltage range from +1V to +5.5V.

Applications

Digital system power supply monitoring
Low-battery detection circuits
Secondary power supply supervision

Procurement Notes

Verify component authenticity through authorized distributors due to potential availability constraints. Confirm RoHS compliance status as indicated in official documentation. Ensure the specific suffix matches required pinout and electrical specifications. Review datasheet revisions for any updates to operating conditions or packaging details before integration.

Selection Notes

Select this component when a fixed 4.38V reset threshold is required for systems powered between 1V and 5.5V. The integrated power-fail output distinguishes it from basic reset generators, making it suitable for applications needing early warning of voltage drops. Consider the SOT-23-6 package size for space-constrained designs requiring high-temperature operation up to 125°C.

Part Context

This part belongs to the MAX6342–MAX6345 family of µP supervisory circuits designed to replace separate ICs or discrete components. These devices enhance system accuracy and reliability by providing precise, factory-trimmed thresholds. The family covers various reset voltages from 2.33V to 4.63V, with the MAX6344 specifically offering the 4.38V setting.

Replacement Considerations

Direct substitutes include other members of the MAX634x family such as MAX6344MUT or MAX6344UR, which share identical electrical characteristics but differ in package type. Verify that alternative packages match the PCB footprint requirements.
