MAX6345MUT-T

Overview

The MAX6345MUT-T is a microprocessor supervisory circuit from the MAX6342–MAX6345 family, designed to monitor power supplies in digital systems. It operates with supply voltages between +1V and +5.5V and features a fixed reset threshold voltage of +4.63V. The device includes a +1.25V threshold detector for power-fail warnings or low-battery detection. It utilizes an active-low push-pull reset output and lacks manual reset or watchdog timer functions. The component is housed in a compact SOT-23-6 package and supports surface-mount installation.

Feature Summary

• Provides factory-trimmed reset threshold voltage for improved system reliability
• Integrates a dedicated power-fail comparator for additional monitoring capabilities
• Features an active-low push-pull reset output for direct logic interfacing

Applications

• Digital system power supply monitoring
• Low-battery detection circuits
• Power-fail warning generation

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status as documentation may vary by production batch. Ensure the operating temperature range aligns with your application requirements before finalizing procurement decisions.

Selection Notes

Select this component when a fixed high-voltage threshold near 4.63V is required. The integrated power-fail comparator offers an advantage over discrete solutions. Verify that the SOT-23-6 package fits your board layout constraints compared to larger packages.

Part Context

This part belongs to the MAX634x series of µP reset circuits. These devices replace separate ICs or discrete components to enhance accuracy. The family covers various threshold voltages from 2.33V to 4.63V, providing standardized supervision for diverse digital applications.

Replacement Considerations

Consider MAX6344MUT-T for a lower fixed threshold of 4.38V within the same package. Other family members like MAX6342 or MAX6343 offer different pin configurations or manual reset inputs.
