MAX6363PUT31-T

Overview

The MAX6363PUT31-T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors a single voltage input and provides an active-low, open-drain reset output with a fixed threshold of 3.15 V. The device features a typical reset delay time of 280 ms and operates within a supply voltage range up to 5.5 V. It draws a maximum quiescent current of 15 uA and functions across an industrial temperature range from -40°C to +85°C. Packaged in a SOT-23-6 surface-mount case, it lacks manual reset and watchdog timer capabilities but includes battery backup switching functionality.

Feature Summary

• Provides precise voltage supervision for microprocessors and memory systems
• Features ultra-low power consumption suitable for battery-operated applications
• Includes dedicated battery backup switch for seamless power transition

Applications

• Microprocessor system reset monitoring
• Battery-powered portable electronics
• Memory protection circuits

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm package marking and datasheet revision alignment. Check regional distribution status as supply may be limited or discontinued in certain markets. Ensure compliance with RoHS directives before integration.

Selection Notes

Select this component when a fixed 3.15 V threshold is required for system supervision. Consider the SOT-23-6 footprint for space-constrained designs. Evaluate the 15 uA quiescent current against total system power budgets. Verify that the absence of a manual reset input aligns with the control logic requirements.

Part Context

This part belongs to the MAX6363P series of low-power MPU supervisors. It shares architectural similarities with other variants in the family, differing primarily in threshold voltage specifications and packaging options. The series is designed for reliable operation in embedded systems requiring stable power management.

Replacement Considerations

Cross-reference with MAX6363PUT31+ for non-tape-and-reel packaging. Verify functional equivalence with MAX6363PUT23-T if a 2.38 V threshold is acceptable. Consult official substitution lists for updated components if this part is discontinued.
