MAX6363PUT26+

Overview

The MAX6363PUT26+ 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 consumes only 15µA of quiescent current, making it suitable for battery-powered applications. The device features a fixed reset threshold voltage of 2.63V with a typical reset delay time of 280ms. It provides an active-low, open-drain reset output and includes a battery backup switch function. The component is housed in a compact SOT-23-6 surface-mount package and is rated for operation over an extended temperature range from -40°C to +85°C.

Feature Summary

• Monitors power-supply voltages and asserts a reset signal when the input falls below the factory-set threshold.
• Includes a battery backup switch that automatically switches between main power and a backup source upon power failure.
• Provides a guaranteed reset timeout period to ensure adequate power-up time for microprocessors.

Applications

• Microprocessor (MPU) system supervision
• Battery-operated portable electronic devices
• Power-fail detection circuits

Procurement Notes

Verify the specific suffix 'PUT26' against the official datasheet to confirm the exact reset threshold voltage and package type. Confirm RoHS compliance status and lead-free specifications directly with the manufacturer or authorized distributors. Check for obsolescence notices or limited availability status prior to finalizing procurement plans.

Selection Notes

Select this component when a fixed 2.63V reset threshold is required for systems operating between 1.2V and 5.5V. The low 15µA supply current makes it appropriate for energy-constrained designs. Ensure the application requires an active-low open-drain output and does not need manual reset or watchdog timer functionality.

Part Context

This part belongs to the MAX6363P series of low-power microprocessor supervisory circuits. The series is designed to monitor single power supplies in portable and industrial applications. It distinguishes itself through ultra-low power consumption and integrated battery backup switching capabilities within a small SOT-23-6 footprint.

Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the MAX6363 family. Verify that any substitute matches the 2.63V threshold, SOT-23-6 package, and electrical characteristics exactly.
