MAX6365LKA31+T

Overview

The MAX6365LKA31+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.2V to 5.5V and draws only 15µA of quiescent current. The device features a fixed reset threshold of 3.08V with an overvoltage threshold of 4.75V. It provides an active-low, push-pull reset output and includes a manual reset input for system control. Key functional blocks include battery backup switching and chip-enable gating. The unit offers a typical reset delay time of 280ms and is housed in an SOT-23-8 package, suitable for portable applications.

Feature Summary

• Integrates battery backup switching to maintain data integrity during main power loss
• Includes chip-enable gating functionality for precise power management control
• Features a manual reset input allowing external assertion of the reset signal

Applications

• Portable consumer electronics requiring low standby current
• Battery-powered systems needing reliable power-fail detection
• Embedded controllers utilizing chip-enable gating for power sequencing

Procurement Notes

Verify the complete part number including suffixes such as +T against official Analog Devices documentation to ensure correct packaging and lead-free compliance. Confirm that the specific revision matches your design requirements, as manufacturing updates may occur. Cross-reference the SOT-23-8 pinout with the latest datasheet before PCB layout finalization to prevent integration errors.

Selection Notes

Select this component when a fixed 3.08V threshold is required alongside battery backup and chip-enable capabilities. It is appropriate for designs prioritizing minimal quiescent current consumption in space-constrained environments. Ensure the application does not require a watchdog timer or adjustable thresholds, as this variant lacks those features.

Part Context

This device belongs to the MAX6365L series of low-power microprocessor supervisors. The family is characterized by ultra-low current consumption and compact SOT-23 packaging. Variants within the series differ primarily in reset threshold voltages and the presence of additional features like watchdog timers or manual resets.
