MAX6367PKA31-T

Overview

The MAX6367PKA31-T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.2V to 5.5V and features a fixed reset threshold voltage of 3.08V. The device provides an active-low, open-drain reset output with a typical reset delay time of 280ms. It includes a battery backup pin for seamless power transition and a chip-enable input for power-down control. Packaged in an SOT-23-8 surface-mount case, it supports manual reset functionality and operates across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates a battery backup switch to maintain system state during primary power loss
• Includes a chip-enable gating function to manage power consumption in standby modes
• Provides a dedicated manual reset input for user-initiated system restarts

Applications

• Portable electronic devices requiring low-power monitoring
• Battery-operated systems needing backup power management
• Industrial control units operating in extended temperature environments

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm the part number corresponds to the 3.08V threshold variant. Check current availability status as distribution may vary. Ensure compatibility with existing PCB footprint for SOT-23-8 packages. Validate RoHS compliance documentation for regulatory requirements.

Selection Notes

Select this component when a fixed 3.08V threshold is required for system supervision. Consider the open-drain output type for interfacing with various logic families. Evaluate the need for battery backup and chip-enable features against system power management goals. Verify that the SOT-23-8 package fits the design constraints. Confirm operational temperature range meets application specifications.

Part Context

This part belongs to the MAX6367P series of low-power supervisors. It shares functional similarities with other MAX6367 variants but differs in threshold voltage and output configuration. The series is designed for applications requiring reliable reset generation under varying supply conditions. It complements other Maxim Integrated PMIC solutions for comprehensive power management.

Replacement Considerations

Direct substitutes include other MAX6367 variants with compatible thresholds and packages. Verify electrical parameters such as threshold voltage and reset delay before substitution. Ensure pinout compatibility for SOT-23-8 packages. Check for any differences in battery backup or chip-enable functionality.
