MAX6328UR25

Supervisors Overview

The MAX6328UR25+T is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 2.5 V with an overvoltage threshold of 2.537 V. The device provides an active low, open-drain output with a reset delay time of 185 ms. It consumes a maximum operating supply current of 500 nA and maintains an accuracy of 1.5%. The component is housed in a SOT-23-3 package and supports surface mount installation. It functions without manual reset, watchdog timer, or battery backup switching capabilities.

Supervisors Feature Summary

Supervisors Procurement Notes

Verify the specific suffix (+T) indicates tape and reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required threshold voltage specifications for the target application circuit design.

Supervisors Selection Notes

Select this component when a fixed 2.5 V threshold is required for single-channel voltage monitoring. Consider the 185 ms reset delay and open-drain output configuration for compatibility with downstream logic circuits. Evaluate the 500 nA quiescent current against strict power budget constraints for portable applications.

Supervisors Part Context

This part belongs to the MAX6328U series of ultra-low-power reset circuits. The series offers various fixed threshold voltages to accommodate different supply rail requirements while maintaining consistent low-power performance characteristics across the family.
