MAX6361PUT44+T

Overview

The MAX6361PUT44+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 1.02V to 5.5V and features a fixed threshold voltage of 4.38V for monitoring a single input. The device provides an active-low, open-drain reset output with a minimum reset timeout of 150ms. It includes a manual reset (MR) input and supports battery backup functionality. Packaged in a surface-mount SOT-23-6 case, it functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Includes a manual reset input for system control
• Supports battery backup switching operations
• Provides active-low open-drain reset signaling

Applications

• Microprocessor power supply supervision
• Battery backup circuit management
• Portable electronic device power monitoring

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm package integrity and pin alignment upon receipt. Ensure storage conditions comply with moisture sensitivity levels specified in the datasheet. Cross-reference ordering information with official documentation to validate suffix designations and manufacturing dates before integration into production workflows.

Selection Notes

Select this component when a fixed 4.38V threshold is required for single-input voltage monitoring. The active-low open-drain output suits interfaces requiring external pull-ups. Manual reset capability allows for controlled system restarts. Verify that the SOT-23-6 package fits the PCB layout constraints and that the operating temperature range meets environmental requirements.

Part Context

This part belongs to the MAX6361 series of low-power MPU supervisors. It shares functional similarities with other variants in the family but differs in threshold voltage and output configuration. The PUT44 designation specifically indicates the 4.38V threshold and push-pull/open-drain characteristics defined by the manufacturer's coding scheme.

Replacement Considerations

Direct substitutes include MAX6361LUT44+T and MAX6361PUT44+T variants with matching thresholds. Verify pin compatibility and electrical specifications before substitution.
