MAX6363LUT44-T

Overview

The MAX6363LUT44-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 4.40V. The device provides an active-low, push-pull output with a typical reset delay time of 280ms. It includes a battery backup switch for seamless power transition monitoring. The component functions without a manual reset input or watchdog timer. It is housed in a compact SOT-23-6 package and supports operation across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a battery backup switch to monitor transitions between main power and backup sources
• Provides a dedicated active-low push-pull reset output signal
• Operates with ultra-low quiescent current suitable for battery-powered applications

Applications

• Microprocessor system power supervision
• Battery backup power management circuits
• Portable electronic device power control

Procurement Notes

Verify the exact suffix configuration against official datasheets, as variations exist within the MAX6363 family. Confirm availability status directly with authorized distributors, as this specific part number may be subject to limited supply or discontinuation notices. Ensure the selected variant matches the required threshold voltage and package type for your design.

Selection Notes

Select this component when a fixed 4.40V threshold is required for single-supply monitoring. The SOT-23-6 package offers space efficiency for portable designs. Consider the MAX6363PUT series if an open-drain output is preferred over the push-pull configuration provided here. Verify that the 280ms reset delay meets the timing requirements of the target processor.

Part Context

This component belongs to the MAX6363L series of low-power microprocessor supervisors. The 'L' designation typically indicates specific threshold characteristics, while the 'UT' suffix denotes the SOT-23-6 package and the '44' specifies the 4.40V threshold. This series is designed for applications requiring reliable power management with minimal power consumption.

Replacement Considerations

The MAX6363LUT44+T is the lead-free equivalent of this part. Other variants in the MAX6363 family with different thresholds (e.g., LUT23, LUT26) may serve as functional substitutes if the voltage level permits.
