MAX6365PKA29+T

Overview

The MAX6365PKA29+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.6 V to 5.5 V and features a fixed overvoltage threshold of 3 V. The device provides an active-low, open-drain reset output with a typical reset delay time of 280 ms. It includes a manual reset input and chip-enable gating functionality for power management control. The circuit supports battery backup switching and consumes only 15 µA of quiescent current. It is housed in an SOT-23-8 package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates battery backup switching capability to manage power transitions between main and auxiliary sources.
• Provides chip-enable gating to control system power states based on supervisory signals.
• Features a manual reset input allowing external initiation of the reset sequence.
• Delivers an active-low open-drain reset signal for interfacing with various logic families.

Applications

• Portable medical instruments requiring reliable power monitoring
• Battery-operated consumer electronics systems
• Industrial control units needing voltage supervision
• Embedded computing modules with backup power requirements

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation before ordering. Confirm RoHS compliance status and specific packaging options such as reel or cut tape availability through authorized distributors. Ensure the sourcing channel is an authorized partner to guarantee component authenticity and traceability. Check for any recent product change notices that may affect specifications or lifecycle status.

Selection Notes

Select this component when a low-quiescent-current supervisor with battery backup and chip-enable features is required. The fixed 3 V threshold suits applications monitoring standard 3.3 V or 5 V rails where overvoltage protection is necessary. Consider the SOT-23-8 package size for space-constrained designs. Verify that the active-low open-drain output aligns with the target system's logic interface requirements.

Part Context

This device belongs to the MAX6365P series of low-power microprocessor supervisors. The series is characterized by minimal power consumption and integrated battery backup management. These components are designed to ensure system stability by monitoring supply voltages and managing power switches during brown-out or overvoltage events.

Replacement Considerations

Consult official substitution guides for compatible parts within the MAX6365 family. Verify pin compatibility and electrical parameter alignment before replacing. Cross-reference datasheets to confirm identical threshold voltages and package dimensions.
