MAX6364PUT31+T

Overview

The MAX6364PUT31+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.2V to 5.5V and features a fixed reset threshold of 3.08V. The device provides an active-low, open-drain output with a typical reset delay time of 280ms. It includes a battery backup pin for seamless power transition monitoring and is housed in a compact SOT-23-6 surface-mount package. The circuit draws only 15µA of quiescent current, making it suitable for portable applications.

Feature Summary

• Monitors single power supply voltage with factory-set threshold
• Includes dedicated battery backup input for power failure detection
• Provides active-low open-drain reset signal output
• Operates with ultra-low 15µA supply current consumption

Applications

• Portable electronic devices requiring power management
• Battery-operated systems needing backup power supervision
• Microprocessor reset circuits in embedded systems
• Consumer electronics with limited power budgets

Procurement Notes

Verify the exact suffix 'PUT31' against official Analog Devices documentation to confirm the specific 3.08V threshold variant. Confirm RoHS compliance status and lead times through authorized distributors, as availability may vary. Ensure the SOT-23-6 footprint matches your PCB design requirements before procurement.

Selection Notes

Select this component when a fixed 3.08V threshold is required for system reset. Consider the 280ms delay time for compatibility with target processor startup sequences. The SOT-23-6 package offers space efficiency compared to larger packages. Verify that the open-drain output configuration aligns with the pull-up resistor requirements of the connected logic.

Part Context

This part belongs to the MAX636x series of low-power microprocessor supervisors from Maxim Integrated. These devices are designed to monitor power supplies in portable and battery-powered applications. The series typically offers various threshold voltages and package options to suit different design constraints while maintaining low quiescent current consumption.

Replacement Considerations

Check Analog Devices datasheets for direct replacements within the MAX6364 family with different thresholds or outputs. Cross-reference with MAX6363 or MAX6365 series parts if manual reset or chip-enable features are needed instead.
