MAX6364PUT31-T

Overview

The MAX6364PUT31-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 up to 5.5 V and features a fixed threshold voltage of 3.08 V for monitoring power rails. The device provides an active high, open-drain reset output with a standard reset delay time of 280 ms. It includes battery backup switching capabilities to maintain supervision during power transitions. Packaged in a compact SOT-23-6 surface-mount format, it supports operation across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrated battery backup switching functionality
• Active high open-drain reset output configuration
• Compact SOT-23-6 surface-mount packaging

Applications

• Microprocessor system power supervision
• Battery-powered portable devices
• Industrial control systems requiring voltage monitoring

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability requirements before integration. Ensure storage conditions align with moisture sensitivity level specifications to prevent package damage during assembly processes.

Selection Notes

Select this variant when an active high reset signal is required rather than the more common active low configuration. The fixed 3.08 V threshold suits 3.3 V logic systems. Verify that the open-drain output capability matches the downstream logic input requirements without additional pull-up components if already present on the board.

Part Context

This component belongs to the MAX636x series of CMOS microprocessor supervisory circuits designed for reliable power management. The PUT31 suffix indicates the specific 3.08 V threshold voltage setting within the family. These circuits are engineered to provide stable reset signals for complex digital systems under varying power conditions.

Replacement Considerations

Cross-reference with other MAX6364 variants differing only in threshold voltage or output polarity. Ensure substitute parts match the SOT-23-6 footprint and electrical characteristics such as supply current and reset delay times.
