MAX6367LKA26+T

Overview

The MAX6367LKA26+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 fixed threshold voltage of 2.63 V for monitoring power rails. The device provides an active-low, push-pull reset output with a minimum reset timeout of 150 ms. Designed for surface-mount installation, it utilizes an SOT-23-8 package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates battery backup circuitry to maintain system state during power transitions
• Delivers precise voltage supervision via a dedicated threshold detection mechanism
• Provides a robust push-pull reset signal for direct microprocessor interface

Applications

• Portable electronic devices requiring low standby current
• Battery-powered systems needing reliable power-fail detection
• Embedded controllers utilizing single-supply architectures

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific lot traceability requirements before integration. Ensure packaging specifications match handling capabilities. Review datasheet revisions for any functional updates that may impact design compatibility.

Selection Notes

Select this component when a fixed 2.63 V threshold aligns with the target supply rail. The push-pull output eliminates the need for external pull-up resistors, simplifying board layout. Consider the SOT-23-8 footprint for space-constrained designs. Verify that the 150 ms timeout meets system startup timing requirements without additional external components.

Part Context

This part belongs to the MAX6367 series of uP supervisors, which are optimized for low-power applications. The series typically includes variants with different thresholds and packages. The LKA suffix indicates specific threshold and package characteristics within the Maxim Integrated portfolio, distinguishing it from other supervisory families like the MAX6365 or MAX6747.

Replacement Considerations

Direct substitutes include MAX6367LKA26+ (without tape/reel suffix) or other MAX6367 variants with identical 2.63 V thresholds and SOT-23-8 packaging. Cross-reference pinouts and electrical characteristics carefully to ensure compatibility.
