MAX6368HKA31+T

Overview

The MAX6368HKA31+T is a low-power voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of up to 5.5 V and features an adjustable overvoltage threshold. The device provides a reset delay time of 280 ms and draws a typical operating supply current of 15 uA. It utilizes an SOT-23-8 package for surface mount installation. The component supports battery backup switching and includes a chip enable signal for power management control.

Feature Summary

• Integrates battery backup switching capability for seamless power transition monitoring
• Includes chip enable gating functionality to manage power consumption states
• Provides active high open drain output configuration for system reset signaling

Applications

• Portable electronic devices requiring low standby current
• Battery-powered systems with backup power switching requirements
• Embedded controllers needing voltage supervision with chip enable control

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to discontinued status. Confirm RoHS compliance documentation matches specific manufacturing lot requirements. Validate package integrity and pin alignment against SOT-23-8 specifications before integration into design files.

Selection Notes

Select this variant when an active high open drain output is required alongside battery backup support. Ensure the adjustable overvoltage threshold meets system protection needs. Verify that the 280 ms reset delay aligns with processor startup timing requirements. Confirm compatibility with the 5.5 V maximum supply voltage limit.

Part Context

This part belongs to the MAX6368H series of supervisory circuits designed for low-power applications. It shares the SOT-23-8 footprint with other variants in the family but differs in output type and threshold settings. The H suffix indicates specific electrical characteristics distinct from L or P series counterparts.
