MAX6363PUT23-T

Overview

The MAX6363PUT23-T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of up to 5.5 V and features a fixed threshold voltage of 2.5 V. The device provides an active-low, open-drain reset output with a typical reset delay time of 280 ms. Designed for surface-mount applications, it is housed in a compact SOT-23-6 package. The circuit draws a maximum operating supply current of 15 uA and supports battery backup functionality. It functions without manual reset inputs or watchdog timers, ensuring reliable system monitoring across industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Provides continuous voltage supervision for single-input power rails
• Features low quiescent current consumption for extended battery life
• Includes dedicated battery backup pin for seamless power transition
• Delivers active-low open-drain reset signal upon undervoltage detection

Applications

• Microprocessor power supply monitoring in embedded systems
• Battery-operated portable electronic devices requiring low standby current
• Industrial control units needing reliable voltage supervision under varying temperatures
• Communication equipment power management circuits

Procurement Notes

Verify the exact suffix designation, as datasheets typically list MAX6363PUT23+T. Confirm availability status, as this component may be discontinued or subject to limited supply constraints depending on the manufacturer's production lifecycle. Ensure compatibility with existing PCB footprints and verify RoHS compliance documentation before finalizing procurement orders.

Selection Notes

Select this component when a fixed 2.5 V threshold is required for system reset logic. Consider the open-drain output configuration for compatibility with various logic families. Evaluate the 15 uA supply current against total system power budgets. Verify that the absence of a manual reset input aligns with the system design requirements.

Part Context

This part belongs to the MAX6363P series of low-power MPU supervisors. It shares functional similarities with other Maxim Integrated supervisory circuits but is distinguished by its specific 2.5 V threshold and SOT-23-6 packaging. The series is designed for applications prioritizing low power consumption and compact form factors in digital system monitoring.

Replacement Considerations

Check for direct substitutes within the MAX6363 family with different thresholds if voltage levels differ. Verify pinout compatibility with alternative SOT-23-6 supervisory ICs from other manufacturers. Ensure replacement parts maintain similar reset delay times and supply current specifications.
