MAX6368PKA31-T

Overview

The MAX6368PKA31-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 fixed threshold voltage of 3.08 V for monitoring a single input. The device provides an active high, open-drain output with a reset delay time of 280 ms. It includes battery backup switching and chip-enable gating capabilities but lacks manual reset and watchdog timer functions. The component supports surface mount installation in an SOT-23-8 package and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates battery backup switching to maintain system state during power transitions
• Includes chip-enable gating functionality for controlled operation
• Provides open-drain output configuration for flexible interfacing

Applications

• Microprocessor system voltage supervision
• Battery-powered electronic devices requiring power management
• Embedded systems needing reliable reset generation

Procurement Notes

Verify the exact suffix designation against official manufacturer documentation, as availability and specific electrical characteristics may vary between tape-and-reel and cut-tape variants. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as supply constraints can affect delivery schedules for this component series.

Selection Notes

Select this component when a fixed 3.08 V threshold is required for single-input voltage monitoring. Ensure compatibility with active-high logic requirements due to the open-drain output type. Verify that the absence of a manual reset input and watchdog timer aligns with the system design specifications before finalizing the part selection.

Part Context

This part belongs to the MAX6368P series of low-power uP supervisory circuits. The series is characterized by ultra-low quiescent current consumption and compact packaging options suitable for space-constrained applications. The MAX6368P family typically integrates essential power management features like battery backup and chip-enable gating within a minimal footprint.

Replacement Considerations

Cross-reference with other MAX6368P series variants having identical threshold voltages and output configurations. Verify pinout compatibility and functional equivalence regarding battery backup and chip-enable features before substituting.
