MAX6365LKA23+T

Overview

The MAX6365LKA23+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of up to 5.5 V and features a threshold voltage of 2.32 V with an overvoltage threshold of 2.38 V. The device draws a typical operating current of 15 uA and provides a reset delay time of 280 ms. It utilizes an SOT-23-8 package, supports active low push-pull outputs, and includes manual reset functionality along with chip-enable gating. The component is rated for operation between -40°C and +85°C.

Feature Summary

• Integrates battery backup switching capability to maintain system state during power transitions.
• Includes chip-enable gating logic for controlled power-down management.
• Provides manual reset input for user-initiated system restarts.

Applications

• Low-power microprocessor systems requiring voltage supervision
• Portable electronic devices utilizing battery backup mechanisms
• Embedded controllers needing chip-enable power management

Procurement Notes

Verify the specific suffix 'LKA23' to confirm the 2.32 V threshold voltage variant. Confirm RoHS compliance status through official documentation. Check current lifecycle status as distribution availability may be limited or discontinued. Ensure the SOT-23-8 package footprint matches the design requirements before procurement.

Selection Notes

Select this component when a low quiescent current of 15 uA is required alongside manual reset and chip-enable features. The 2.32 V threshold suits applications monitoring 3.3 V or similar rails. Verify that the SOT-23-8 package fits the board space constraints. Consider the 280 ms reset delay timing against the target processor's startup requirements.

Part Context

This part belongs to the MAX6365L series of low-power supervisory circuits. It shares functional similarities with other Maxim Integrated supervisors but is distinguished by its specific combination of manual reset, chip-enable gating, and battery backup support in an SOT-23-8 package.
