MAX6363LUT46

Overview

The MAX6363LUT46 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 of 4.63V. The device monitors a single voltage rail and provides a push-pull active-low output. It includes a manual reset input and battery backup functionality to maintain system integrity during power transitions. The component is available in a compact SOT-23-6 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates battery backup capability to preserve critical data during power loss events
• Provides precise voltage monitoring with a fixed threshold for reliable system reset generation
• Includes a manual reset input pin allowing external control over the reset state

Applications

• Portable electronic devices requiring low-power supervision
• Battery-operated systems needing backup power management
• Embedded controllers requiring stable reset signals under varying voltage conditions

Procurement Notes

Verify the specific suffix 'LUT46' to confirm the 4.63V threshold and SOT-23-6 package configuration. Ensure compatibility with the target system's voltage levels and temperature requirements. Confirm RoHS compliance status if required by regulatory standards. Check current availability as distribution may be limited or subject to factory order constraints.

Selection Notes

Select this component when a fixed 4.63V reset threshold is required for 5V logic systems. Consider the SOT-23-6 package for space-constrained designs. Evaluate the need for battery backup functionality and manual reset inputs. Compare power consumption against other supervisory circuits if ultra-low quiescent current is a primary design constraint.

Part Context

This part belongs to the MAX6363 series of low-power supervisory circuits designed for microprocessor applications. The series offers various threshold voltages and package options to suit different system requirements. Maxim Integrated specializes in power management and signal conditioning solutions, ensuring reliability in industrial and consumer electronics environments.

Replacement Considerations

Check for direct cross-references within the MAX6363 family with matching thresholds. Verify pinout compatibility before substituting with similar supervisory ICs from other manufacturers. Ensure equivalent operating temperature ranges and package dimensions are maintained.
