MAX6363LUT46+T

Overview

The MAX6363LUT46+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices / Maxim Integrated. It operates within a supply voltage range of 1.2V to 5.5V and features a fixed reset threshold voltage of 4.63V. The device provides an active-low, push-pull output with a typical reset delay time of 280ms. It includes a battery backup switch for maintaining system state during power transitions. The component draws a maximum quiescent current of 15µA and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates a battery backup switch to support seamless power source transitions
• Provides a dedicated manual reset input for user-initiated system control
• Features a factory-programmed reset threshold voltage for precise monitoring

Applications

• Portable electronic devices requiring low standby current
• Battery-powered systems needing reliable power supervision
• Microprocessor-based circuits requiring automated reset generation

Procurement Notes

Verify the exact suffix designation, as the provided model number differs from standard catalog listings which typically use LUT23 or PUT23. Confirm availability status directly with authorized distributors, as this specific variant may be subject to limited supply or discontinuation. Ensure the package type matches the required PCB footprint before finalizing procurement orders.

Selection Notes

Select this component when a fixed high-voltage threshold near 4.63V is required for single-supply monitoring. The integrated battery backup feature distinguishes it from basic supervisors, making it suitable for applications preserving volatile memory states. Verify that the push-pull output capability aligns with the downstream logic interface requirements.

Part Context

This part belongs to the MAX6363 series of low-power microprocessor supervisors. The series is characterized by minimal quiescent current consumption and compact SOT-23 packaging. These devices are designed to replace discrete resistor networks and comparators in space-constrained portable electronics.

Replacement Considerations

Cross-reference with MAX6363LUT23+T or MAX6363PUT23+T for similar functionality. Verify that alternative parts match the 4.63V threshold requirement and confirm compatibility with the existing battery backup circuit design.
