MAX6363PUT46-T

Overview

The MAX6363PUT46-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 1.2V to 5.5V and features a fixed reset threshold voltage of 4.63V. The device provides an active-low, open-drain output with a typical reset delay time of 280ms. It is designed for single-input monitoring without manual reset or watchdog timer functionality. The component supports battery backup switching and operates reliably across an extended temperature range from -40°C to +85°C.

Feature Summary

• Provides reliable power system supervision for microprocessors and digital systems
• Integrates battery backup switching to maintain data integrity during power transitions
• Delivers a stable active-low open-drain reset signal upon voltage fault detection

Applications

• Microprocessor power supply monitoring in embedded systems
• Battery-powered devices requiring backup switching capabilities
• Portable electronics needing low-quiescent current supervision

Procurement Notes

Verify the exact suffix configuration against official datasheets, as variations exist within the MAX6363 family. Confirm availability status directly with authorized distributors, as this specific part number may be subject to limited supply or discontinuation. Ensure compatibility with your board's SOT-23-6 footprint and voltage requirements before finalizing procurement decisions.

Selection Notes

Select this component when a fixed 4.63V threshold is required for single-supervision applications. Consider the SOT-23-6 package for space-constrained designs. Evaluate the 15uA quiescent current against system power budgets. Verify that the open-drain output type aligns with the downstream logic interface requirements.

Part Context

This part belongs to the MAX6363P series of low-power supervisors. It shares architectural similarities with other members like the MAX6363LUT23+T but differs in threshold voltage and output drive characteristics. The series is designed for general-purpose voltage monitoring in consumer and industrial electronics where power efficiency is critical.

Replacement Considerations

Check for direct pin-compatible alternatives within the MAX6363 family with matching 4.63V thresholds. Verify if the MAX6363PUT23+T or similar variants meet the specific voltage and package requirements. Cross-reference electrical parameters to ensure functional equivalence.
