MAX6365LKA23

Overview

The MAX6365LKA23 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 provides an active low, push-pull output and includes manual reset functionality along with chip-enable gating. It incorporates a battery backup switch and offers a reset delay time of 280 ms. Designed for surface mount installation in an SOT-23-8 package, it supports a quiescent current of 15 uA and functions reliably across a temperature range from -40 C to +85 C.

Feature Summary

• Integrates battery backup switching capability to maintain system state during power transitions
• Provides chip-enable gating for controlled power management and standby optimization
• Delivers active low push-pull reset signals with manual reset input support

Applications

• Microprocessor power supply monitoring in embedded systems
• Battery-powered devices requiring backup power management
• Industrial control circuits needing reliable voltage supervision

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeit risks. Confirm RoHS compliance status and specific lot codes against the official datasheet specifications. Check lead times and availability as this series may be subject to limited supply or end-of-life restrictions. Ensure packaging format matches design requirements before finalizing procurement orders.

Selection Notes

Select this component when active low push-pull outputs and manual reset inputs are required alongside battery backup functionality. The 2.32 V threshold suits applications monitoring 3.3 V or similar logic levels. Consider the SOT-23-8 footprint for space-constrained designs. Verify that the 15 uA quiescent current aligns with low-power system constraints and that the 280 ms reset delay meets timing requirements.

Part Context

This part belongs to the MAX6365L series of low-power microprocessor supervisory circuits. It shares functional similarities with other variants in the family but differs in specific threshold voltages and pin configurations. The MAX6365LKA23 specifically targets applications requiring precise voltage monitoring with integrated battery backup and chip-enable features, distinguishing it from simpler supervisor ICs lacking these advanced control capabilities.

Replacement Considerations

MAX6365LKA29+T: Offers a higher threshold voltage of 2.93 V while maintaining identical package and feature set. Suitable if system voltage levels require adjustment. Other MAX6365L variants with different suffixes provide alternative thresholds but must match the SOT-23-8 package and pinout for direct replacement.
