MAX6367LKA31+

Overview

The MAX6367LKA31+ is a low-power voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range up to 5.5 V and features a fixed reset threshold of 3.08 V. The device provides an active-low, push-pull output with a typical reset delay time of 280 ms. It includes battery backup functionality and chip-enable gating for power management control. The component is housed in an SOT-23-8 surface-mount package and supports operation across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates battery backup switching capability to maintain system state during power transitions.
• Features chip-enable gating to allow external control over the supervisory function.
• Delivers a deterministic reset pulse via an active-low push-pull output stage.

Applications

• Microprocessor power supply monitoring
• Battery-backed memory systems
• Portable electronic devices requiring low quiescent current

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm RoHS compliance status and specific lot traceability requirements before integration. Ensure the ordering suffix matches the required tape-and-reel or cut-tape packaging format for automated assembly processes.

Selection Notes

Select this part when a fixed 3.08 V threshold is required for single-input monitoring. The inclusion of chip-enable and battery backup distinguishes it from standard supervisors. Verify that the SOT-23-8 footprint aligns with the PCB layout constraints and that the 280 ms delay meets the target processor's timing specifications.

Part Context

This component belongs to the MAX6367L series of uPower Supervisors designed for low-voltage applications. It shares functional similarities with the MAX6365 and MAX6368 families but offers specific threshold and feature combinations tailored for compact embedded designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate cross-reference options based on identical pinout, threshold voltage, and package dimensions while verifying electrical parameter compatibility.
