MAX6365PKA26-T

Overview

The MAX6365PKA26-T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.0V to 5.5V and features a fixed reset threshold voltage of 2.63V with an overvoltage threshold of 4.75V. The device provides a push-pull active-low output and includes a manual reset input alongside chip-enable gating functionality. It incorporates battery backup switching and offers a typical reset delay time of 280ms. Designed for surface-mount applications, it utilizes an SOT-23-8 package and maintains a low operating supply current of 15µA across the industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates chip-enable gating to control system power states based on external logic signals
• Provides automatic battery backup switching to maintain critical data during main power loss
• Includes a manual reset input pin allowing for user-initiated system restarts

Applications

• Portable consumer electronics requiring extended battery life
• Embedded systems needing reliable brown-out protection
• Industrial control units operating in harsh environmental conditions

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm specific tape-and-reel packaging requirements against design specifications. Ensure compliance with RoHS directives and REACH regulations prior to integration. Validate that the SOT-23-8 footprint matches existing PCB layouts. Review datasheet revisions for any recent parameter updates affecting long-term supply chain stability.

Selection Notes

Select this component when precise voltage monitoring is required alongside active system enablement control. The integrated battery backup feature simplifies design complexity compared to discrete solutions. Consider the 15µA quiescent current for strict power budget constraints. Verify that the 2.63V threshold aligns with the target rail voltage. Evaluate the SOT-23-8 package size against available board space limitations.

Part Context

This part belongs to the MAX6365L series of low-power microprocessor supervisors. The family is characterized by minimal external component requirements and high accuracy thresholds. Variants within the series differ primarily in reset threshold voltages and package options. The MAX6365 specifically emphasizes chip-enable gating capabilities for advanced power management sequences.

Replacement Considerations

Consult official cross-reference documentation for verified substitutes. Ensure replacement parts match the SOT-23-8 package and functional pinout. Verify identical threshold voltages and reset timing characteristics. Confirm compatibility with existing chip-enable and manual reset circuitry.
