MAX6366LKA31-T

Overview

The MAX6366LKA31-T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 0 to 5.5 V and features a fixed reset threshold of 3.08 V. The device provides a push-pull, active-low output with a typical reset timeout delay of 280 ms. Packaged in an SOT-23-8, it integrates battery backup switching and chip-enable gating functions for memory write protection.

Feature Summary

• Integrates battery backup switching and chip-enable gating for memory protection
• Provides active-low push-pull reset output signal
• Supports microprocessor power-supply monitoring applications

Applications

• Microprocessor system power supervision
• Battery backup control circuits
• Memory write protection systems

Procurement Notes

Verify the specific suffix (+T vs -T) against the manufacturer's current datasheet to confirm lead-free status and exact electrical tolerances. Ensure the SOT-23-8 package footprint matches the design requirements. Confirm that the 3.08 V threshold aligns with the target supply rail before procurement.

Selection Notes

Select this component when a fixed 3.08 V threshold is required for systems operating up to 5.5 V. The integrated battery backup and chip-enable features reduce external component count compared to basic supervisors. Verify that the 280 ms timeout meets the minimum initialization time requirements of the monitored microprocessor or memory devices.

Part Context

This part belongs to the MAX6365–MAX6368 family of low-power µP supervisory circuits. These devices are designed to simplify power-supply monitoring and battery-backup control. The LKA31 variant specifically denotes the 3.08 V threshold option within the SOT-23-8 package configuration.

Replacement Considerations

The MAX6366LKA26+T is a documented alternative within the same family, offering a different reset threshold voltage while maintaining similar package and functional characteristics.
