MAX6365PKA44+

Overview

The MAX6365PKA44+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range up to 5.5 V and features a single monitored input with a threshold voltage of 4.38 V and an overvoltage threshold of 4.5 V. The device provides active-low, open-drain output and includes manual reset functionality. It incorporates battery backup switching and chip-enable gating capabilities. The IC supports a reset delay time of 280 ms and consumes only 15 uA of operating current. It is housed in an SOT-23-8 package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates battery backup switching for seamless power transition management
• Includes chip-enable gating to control circuit operation states
• Provides manual reset capability for system initialization control

Applications

• Portable electronic devices requiring low-power supervision
• Battery-operated systems needing backup power monitoring
• Microprocessor-based circuits requiring reliable reset generation

Procurement Notes

Verify the exact suffix designation (+T) against official manufacturer documentation to confirm packaging type and availability status. Confirm that the specific part number matches the required threshold voltages and functional features such as battery backup and chip-enable gating before procurement. Cross-reference with authorized distributors to ensure authenticity and compliance with RoHS standards.

Selection Notes

Select this component when a single-channel supervisor with battery backup and chip-enable features is required. Ensure the 4.38 V threshold aligns with the monitored rail voltage. Verify that the SOT-23-8 package fits the design constraints. Consider the 15 uA quiescent current for battery life optimization in portable applications.

Part Context

This part belongs to the MAX6365P series of low-power P-MOSFET supervisors. It is designed for applications demanding minimal current consumption while providing essential voltage monitoring and reset functions. The series typically integrates battery backup and chip-enable features, distinguishing it from basic supervisor ICs.

Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Generic equivalents may lack specific features like battery backup or chip-enable gating. Ensure any substitute matches the SOT-23-8 package and electrical specifications.
