MAX6361LUT46+

Overview

The MAX6361LUT46+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 2.3 V to 5.5 V and features a fixed reset threshold voltage of 4.6 V. The device provides an active high, open-drain output and includes a manual reset input for system control. It incorporates a battery backup switch to maintain functionality during power transitions. The component is available in a compact SOT-23-6 surface-mount package and supports operation across an extended temperature range from -40°C to +85°C.

Feature Summary

• Integrates a battery backup switch to ensure continuous monitoring during power source transitions
• Provides manual reset capability via dedicated input pin for controlled system initialization
• Delivers active high open-drain reset output compatible with various logic families

Applications

• Portable electronic devices requiring reliable power supervision
• Battery-operated systems needing backup power management
• Embedded controllers requiring manual reset functionality

Procurement Notes

Verify exact ordering suffixes as distributors may list variants with different packaging or temperature grades. Confirm availability status directly with authorized suppliers due to potential limited stock conditions. Ensure the selected part matches the required SOT-23-6 package and electrical specifications for your design.

Selection Notes

Select this component when a fixed 4.6 V threshold is required for voltage monitoring. Consider the active high open-drain output configuration for interface compatibility. Evaluate the need for manual reset and battery backup features against alternative supervisory circuits with different output polarities or thresholds.

Part Context

This part belongs to the MAX6361H series of low-power MPU supervisors. It shares functional similarities with other members of the family but differs in specific threshold voltages and output configurations. The series is designed for applications demanding minimal quiescent current and compact footprint solutions.

Replacement Considerations

Check for direct substitutes within the MAX6361 series offering identical 4.6 V thresholds. Verify pinout compatibility before replacing with other supervisory ICs. Ensure any alternative maintains the same active high open-drain output type and manual reset support.
