MAX6363LUT31-T

Overview

The MAX6363LUT31+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 up to 5.5 V and features a threshold voltage of 2.5 V. The device provides an active-low, push-pull output with a reset delay time of 280 ms. It includes a battery backup switch for maintaining system state during power transitions. The component draws a typical operating supply current of 15 uA and functions reliably across a temperature range from -40 C to +85 C. Packaged in a compact SOT-23-6 surface-mount format, it lacks manual reset and watchdog timer capabilities.

Feature Summary

• Integrates a dedicated battery backup switch to preserve critical data during power loss events
• Provides precise voltage monitoring with a fixed 2.5 V threshold for reliable system supervision
• Delivers a deterministic 280 ms reset delay to ensure stable power-up sequencing

Applications

• Low-power microprocessor systems requiring voltage supervision
• Battery-operated devices needing backup power management
• Embedded controllers with strict power-down protection requirements

Procurement Notes

Verify exact part number suffixes as distributor listings may vary. Confirm availability status directly with authorized channels due to potential limited stock or discontinuation risks. Ensure RoHS compliance documentation matches specific manufacturing dates. Cross-reference datasheet revisions to confirm pinout and electrical characteristics remain unchanged before finalizing procurement orders.

Selection Notes

Select this component when a fixed 2.5 V threshold is required for system supervision. The SOT-23-6 package suits space-constrained designs. Verify that the active-low push-pull output aligns with the target microprocessor input requirements. Consider the 15 uA quiescent current for battery life calculations. Ensure the absence of a watchdog timer meets the application's safety needs.
