MAX6368LKA23-T

Overview

The MAX6368LKA23-T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range up to 5.5 V and monitors a single input channel with an adjustable threshold voltage of 2.32 V. The device features an active-low, push-pull output and includes battery backup functionality for seamless power transitions. It incorporates a chip-enable gating feature and provides a reset delay time of 280 ms. Designed for surface-mount installation in SOT-23-8 packages, it supports operation across temperatures from -40°C to +85°C.

Feature Summary

• Integrates battery backup control functions to manage power transitions between primary and secondary sources.
• Includes chip-enable gating to allow external control over the supervisory circuit's active state.
• Provides memory write protection capabilities to prevent data corruption during power failures.

Applications

• Microprocessor power-supply monitoring systems
• Battery-backed memory circuits requiring write protection
• Portable electronic devices utilizing low-power supervision

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the '23' code corresponds to the 2.32 V threshold variant. Check current lifecycle status as distribution may be limited or discontinued. Ensure compatibility with SOT-23-8 footprint requirements. Validate RoHS compliance documentation for regulatory adherence.

Selection Notes

Select this component when a fixed 2.32 V threshold is required for system supervision. Consider the integrated battery backup feature if seamless power switching is necessary. Evaluate the low quiescent current for battery-operated applications. Ensure the SOT-23-8 package fits the design constraints. Verify that the 280 ms reset delay meets timing requirements.

Part Context

This part belongs to the MAX6368L family of uP supervisory ICs. These circuits are designed to simplify power-supply monitoring and battery-backup control. The family offers various threshold voltages and package options. The MAX6368LKA23-T specifically targets applications needing precise voltage supervision with minimal power consumption.

Replacement Considerations

Cross-reference with other MAX6368L variants sharing the same SOT-23-8 package and 2.32 V threshold. Verify functional equivalence regarding battery backup and chip-enable features. Ensure pinout compatibility for direct replacement. Confirm operating temperature ranges match application needs.
