MAX6367LKA23

Overview

The MAX6367LKA23 is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates with a supply voltage range of +1.2V to +5.5V and features a precise threshold voltage of 2.3V for monitoring power supplies. The device provides an active-low push-pull output and includes a battery backup switch function. It offers a minimum reset timeout period of 150ms and maintains a quiescent supply current of 10µA. The component is housed in an SOT-23-8 package and supports chip-enable gating.

Feature Summary

• Integrates battery-on output indicator for battery backup status
• Provides on-board gating of chip-enable signals with fast propagation delay
• Features debounced manual reset input capability within the series architecture

Applications

• Microprocessor system power-supply monitoring
• Battery-backup control functions
• Memory write protection circuits

Procurement Notes

Verify availability status as this part may be discontinued or subject to limited supply. Confirm RoHS compliance and lead times through authorized distributors. Ensure the specific suffix matches design requirements for threshold voltage and package type before ordering.

Selection Notes

Select this component for applications requiring low quiescent current and integrated battery backup management. The SOT-23-8 package suits space-constrained designs. Verify that the 2.3V threshold aligns with the monitored rail voltage and that the push-pull output structure meets interface requirements.

Part Context

This part belongs to the MAX6365–MAX6368 family of supervisory circuits designed to simplify power-supply monitoring and memory protection. These devices improve system size, accuracy, and reliability by integrating multiple functions into an ultra-small solution compared to discrete implementations.

Replacement Considerations

Check for direct pin-compatible substitutes within the MAX636x series such as MAX6367LKA26+T for different threshold voltages. Verify functional equivalence regarding chip-enable gating and battery backup features when selecting alternatives.
