MAX6363PUT29+T

Overview

The MAX6363PUT29+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.63V to 5.5V and features a fixed threshold voltage of 2.93V for power monitoring. The device provides an active-low, open-drain reset output with a typical reset delay time of 280ms. It includes a battery backup pin to maintain the reset state during power transitions and supports manual reset functionality via an external push-button switch. The component is housed in a compact SOT-23-6 surface-mount package and is rated for operation across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates a battery backup pin to ensure the reset signal remains asserted during power-up and power-down sequences, preventing premature system initialization.
• Includes a manual reset input that allows users to force the reset output low independently of the monitored supply voltage level.
• Offers a low quiescent current consumption profile suitable for battery-operated applications requiring extended operational life.

Applications

• Microprocessor and microcontroller power supply supervision
• Battery-powered portable electronic devices
• Industrial control systems requiring reliable power monitoring

Procurement Notes

Verify the specific suffix '29' corresponds to the required 2.93V threshold voltage before procurement. Confirm the '+T' designation indicates tape-and-reel packaging if automated assembly is planned. Ensure the manufacturer is identified as Analog Devices or Maxim Integrated to guarantee component authenticity and datasheet alignment.

Selection Notes

Select this component when a fixed 2.93V threshold is required for single-supply monitoring. Consider the manual reset feature if system recovery requires user intervention. Evaluate the SOT-23-6 package constraints against available PCB real estate. Compare against other MAX6363 variants if different threshold voltages or additional features like watchdog timers are needed.

Part Context

This part belongs to the MAX6363P series of low-power supervisors. It shares the same functional architecture as other members of the family but differs in its fixed threshold voltage setting. The series is designed for applications where power integrity is critical, offering a balance between low power consumption and robust supervisory functions in a small footprint.

Replacement Considerations

Direct substitutes include other MAX6363PUTxx+T variants with different threshold voltages, provided the voltage level matches the application requirements. Cross-reference with MAX6363PUTxx+ parts for tube-packaged equivalents if reel availability is an issue.
