MAX6361PUT44+

Overview

The MAX6361PUT44+ is a low-power microprocessor supervisor circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.8 V to 5.5 V and features a fixed reset threshold voltage of 4.40 V. The device provides an active-low, open-drain output signal with a manual reset input capability. It incorporates a battery backup switch for seamless power transition monitoring. The reset delay time is specified at 280 ms, ensuring stable system initialization. Operating temperatures range from -40°C to +85°C, and it is housed in a compact SOT-23-6 surface-mount package.

Feature Summary

• Provides reliable voltage supervision with a fixed 4.40 V threshold for precise power monitoring
• Includes a manual reset input allowing external control over system reset states
• Features a battery backup switch to detect transitions between primary and backup power sources

Applications

• Microprocessor power supply monitoring in embedded systems
• Battery-powered devices requiring backup power detection

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lot traceability upon receipt. Check for obsolescence notices as this part may have limited availability. Ensure storage conditions meet semiconductor handling standards to prevent moisture damage prior to assembly.

Selection Notes

Select this component when a fixed 4.40 V threshold is required for system supervision. Consider the manual reset feature if external reset control is necessary. Evaluate the SOT-23-6 package size against board space constraints. Verify that the 280 ms reset delay aligns with the target microprocessor's startup requirements.

Part Context

This part belongs to the MAX6361 series of low-power supervisors designed for portable and industrial applications. It shares functional similarities with other MAX63xx family members but differs in specific threshold voltages and package options. The series emphasizes low quiescent current consumption to extend battery life in mobile devices.

Replacement Considerations

Consult official cross-reference guides for compatible alternatives. Verify pin compatibility and electrical specifications before substitution. Ensure replacement parts maintain the same reset threshold and package dimensions.
