MAX6364LUT44-T

Overview

The MAX6364LUT44-T is a low-power microprocessor supervisory circuit manufactured by Analog Devices under the Maxim Integrated brand. 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 standard reset delay time of 280ms. It is designed for single-input monitoring without manual reset or watchdog timer capabilities but includes a battery backup switch function. The component supports operation across an industrial temperature range from -40°C to +85°C and consumes only 15µA of quiescent current.

Feature Summary

• Integrates a battery backup switch to maintain system state during power transitions
• Delivers precise voltage supervision via a fixed threshold reset mechanism
• Ensures reliable startup through a defined reset pulse duration

Applications

• Portable electronic devices requiring extended battery life
• Embedded systems needing stable power-on sequencing
• Industrial control modules operating in variable thermal environments

Procurement Notes

Verify component authenticity through authorized distribution channels due to limited availability status. Confirm package integrity upon receipt as surface-mount components are sensitive to handling damage. Cross-reference datasheet revision numbers to ensure compatibility with existing design specifications. Validate thermal performance parameters against application requirements before final integration.

Selection Notes

Select this component when a fixed 4.40V threshold is required for single-rail monitoring applications. Consider the SOT-23-6 package constraints for PCB layout optimization. Evaluate the 15µA standby current against total system power budgets. Ensure the absence of manual reset inputs aligns with the intended control architecture.

Part Context

This part belongs to the MAX6363/MAX6364 series of ultra-small, low-power microprocessor reset circuits. These devices are engineered for space-constrained designs where minimal quiescent current is critical. The series typically offers various threshold options and packaging styles to accommodate diverse voltage monitoring needs in portable and industrial electronics.
