MAX6365HKA23+T

Overview

The MAX6365HKA23+T is a low-power microprocessor 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 fixed threshold voltage of 2.32V with an overvoltage threshold of 2.38V. The device provides a manual reset input, chip-enable gating, and battery backup functionality. It utilizes an SOT-23-8 package and delivers an active-low push-pull output with a reset delay time of 280ms. The quiescent current is 15µA, and it functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates manual reset input for user-initiated system control alongside automatic power-fail detection.
• Includes chip-enable gating to manage processor activity during low-voltage conditions.
• Provides battery backup switching to maintain data integrity during primary power loss.

Applications

• Portable electronic devices requiring extended battery life through low-power supervision.
• Embedded systems needing reliable manual reset capabilities for serviceability.
• Battery-operated equipment utilizing backup power switching for memory retention.

Procurement Notes

Verify the specific suffix 'HKA23' against official manufacturer documentation to confirm the exact threshold voltage and package configuration. Ensure compatibility with existing board layouts regarding the SOT-23-8 footprint. Confirm that the manual reset and chip-enable features align with the system design requirements before finalizing procurement decisions.

Selection Notes

Select this component when a supervisory circuit requires both automatic voltage monitoring and manual reset functionality. The inclusion of chip-enable gating makes it suitable for applications where the processor must be disabled during brown-out events. Consider the 15µA quiescent current for battery-sensitive designs and verify that the 2.32V threshold matches the target logic voltage levels.

Part Context

This part belongs to the MAX6365L series of low-power microprocessor supervisory circuits. It shares functional similarities with other parts in the family but is distinguished by its specific threshold voltage and package type. The series is designed for applications demanding minimal power consumption while providing essential reset and backup management features.

Replacement Considerations

Consult official substitution guides for equivalent parts within the MAX6365 or MAX6363 families. Verify pinout compatibility and electrical specifications such as threshold voltage and reset delay time before implementing any alternative components.
