MAX6363PUT26-T

Overview

The MAX6363PUT26-T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors a single power supply input with a fixed threshold voltage of 2.6V. The device features an active-low, open-drain reset output and includes a battery backup switch for seamless transition between power sources. It operates within a supply voltage range up to 5.5V and draws only 15µA of quiescent current. The reset delay time is 280ms, ensuring stable system initialization. The component is housed in a compact SOT-23-6 package and supports surface-mount installation.

Feature Summary

• Integrates a battery backup switch to maintain system continuity during power transitions
• Provides a dedicated active-low open-drain reset signal for reliable logic interfacing
• Designed for ultra-low power consumption suitable for portable applications

Applications

• Microprocessor system supervision
• Portable electronic devices requiring low standby current
• Battery-powered equipment monitoring

Procurement Notes

Verify the exact suffix configuration against official datasheets, as variations exist within the MAX6363 family. Confirm availability status directly with authorized distributors or the manufacturer, as this specific part number may be subject to limited supply or discontinuation. Ensure the selected variant matches the required threshold voltage and output type specifications for your design.

Selection Notes

Select this component when a single-channel supervisor with an integrated battery backup function is required. The open-drain output necessitates an external pull-up resistor, which should be chosen based on the target logic voltage levels. Consider the 280ms reset delay to ensure adequate power ramp-up time for the monitored circuit before asserting the reset signal.

Part Context

This part belongs to the MAX6363 series of low-power MPU supervisors from Maxim Integrated. The series offers various threshold voltages and output configurations to accommodate different system requirements. The PUT suffix typically denotes specific electrical characteristics and packaging options within this product line, distinguishing it from other variants like the LUT series.

Replacement Considerations

Consult official cross-reference guides for verified substitutes. Variants such as MAX6363PUT23+T or MAX6363PUT25+T may serve as alternatives if the threshold voltage difference is acceptable. Verify pinout compatibility and electrical parameters before substitution.
