MAX6363HUT26-T

Overview

The MAX6363HUT26-T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.5 V to 5.5 V and features a fixed reset threshold voltage of 2.60 V. The device provides an active-low, push-pull output with a typical reset delay time of 280 ms. It includes a battery backup switch function but lacks manual reset and watchdog timer capabilities. The component is housed in a compact SOT-23-6 package and supports surface-mount installation. It functions reliably across an industrial temperature range from -40°C to +85°C while consuming only 15 µA of quiescent current.

Feature Summary

• Integrates a low-power voltage supervisor with a dedicated battery backup switch for seamless power transition management.
• Provides a deterministic reset signal via an active-low, push-pull output interface with a fixed 280 ms timeout.
• Operates efficiently at ultra-low quiescent current levels suitable for battery-powered applications.

Applications

• Microprocessor system power monitoring
• Battery backup switching circuits
• Portable electronic device power management

Procurement Notes

Verify the exact suffix configuration against official datasheets, as variations exist within the MAX6363 family. Confirm availability status through authorized distributors, as specific tape-and-reel quantities may vary. Ensure the selected part matches the required threshold voltage and package type for your design. Cross-reference the manufacturer's latest documentation for any updates on lead times or lifecycle status before finalizing procurement plans.

Selection Notes

Select this component when a fixed 2.60 V threshold is required for systems operating between 1.5 V and 5.5 V. The active-low push-pull output simplifies interfacing with digital logic without external pull-up resistors. Consider the 15 µA current consumption for strict power budget constraints. Verify that the absence of a manual reset input aligns with the system's recovery requirements.

Part Context

This part belongs to the MAX6363 series of low-power microprocessor supervisors. The series offers various threshold voltages and output configurations to accommodate different system needs. The HUT suffix indicates a specific threshold voltage and package type within the Maxim Integrated lineup. These devices are designed for high reliability in embedded control applications.

Replacement Considerations

Check for direct pin-compatible alternatives within the MAX6363 series with matching 2.60 V thresholds. Verify that substitute parts maintain the same SOT-23-6 footprint and electrical characteristics. Ensure replacement components support the required battery backup functionality and output drive strength.
