MAX6365PKA31

Overview

The MAX6365PKA31 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 threshold voltage of 2.93 V for monitoring a single input. The device provides an active-low, open-drain output with a reset delay time of 280 ms. Key functional blocks include a battery backup switch and chip-enable gating, while it lacks a manual reset input and watchdog timer. Operating temperatures span from -40°C to +85°C, with a typical quiescent current of 15 µA.

Feature Summary

• Integrates battery backup switching capability for seamless power transition management
• Includes chip-enable gating functionality to control supervisory operation states
• Delivers active-low open-drain reset signal output for system interface compatibility

Applications

• Portable electronic devices requiring low-power voltage supervision
• Battery-operated systems utilizing backup power switching
• Embedded circuits needing chip-enable controlled monitoring

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Ensure packaging specifications match handling needs. Check for obsolescence notices or lifecycle changes as availability may vary. Validate datasheet revisions against design specifications to ensure parameter consistency.

Selection Notes

Select this component when a fixed 2.93 V threshold is required for single-input monitoring. Consider the active-low open-drain output configuration for logic interfacing. Evaluate the 15 µA quiescent current against system power budgets. Verify that the absence of a manual reset input aligns with the system's recovery strategy. Confirm SOT-23-8 package suitability for the PCB layout constraints.

Part Context

This part belongs to the MAX6365P series of low-power supervisory circuits. It shares architectural similarities with other variants in the family but differs in threshold voltage and output polarity. The MAX6365P series is designed for applications demanding minimal standby current and integrated battery backup management within compact surface-mount packages.

Replacement Considerations

Cross-reference with other MAX6365P series variants for different threshold voltages. Verify pinout compatibility if substituting with similar supervisory ICs from other manufacturers. Ensure equivalent electrical characteristics such as reset delay and quiescent current are maintained.
