MAX6328UR24-T

Overview

The MAX6328UR24-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 monitors a single input channel with a threshold voltage of 2.4 V. The device features an active low, open-drain output and provides a reset delay time of 185 ms. It exhibits high accuracy of 1.5% and consumes only 500 nA of operating current. The component is housed in a SOT-23-3 package and functions reliably across a temperature range from -40°C to +85°C.

Feature Summary

• Ultra-low power consumption for extended battery life
• Single-channel voltage monitoring with fixed threshold
• Active low open-drain reset output
• Compact surface-mount packaging

Applications

• Portable electronic devices requiring low standby current
• Battery-powered systems needing voltage supervision
• Embedded microprocessor reset circuits
• Consumer electronics with limited power budgets

Procurement Notes

Verify the specific suffix and tape/reel configuration when ordering. Confirm RoHS compliance status as indicated in official documentation. Check availability through authorized distributors as supply may be limited. Ensure the part number matches the required threshold voltage variant. Validate package type compatibility with your PCB design before procurement.

Selection Notes

Select this component when a fixed 2.4 V threshold is required for system supervision. Consider the 500 nA quiescent current for energy-sensitive designs. Verify that the open-drain output interface suits your logic levels. Ensure the SOT-23-3 footprint fits your board layout constraints. Confirm operational temperature range meets environmental requirements.

Part Context

This part belongs to the MAX6328U series of ultra-low-power reset circuits. It is designed for applications where minimal current draw is critical. The series offers various threshold voltages to accommodate different supply rails. Analog Devices acquired Maxim Integrated, which originally developed this line. The component serves as a reliable supervisor for digital systems.

Replacement Considerations

Check for direct substitutes within the MAX6328 family with compatible thresholds. Verify pinout compatibility if replacing with other SOT-23-3 supervisors. Ensure equivalent electrical characteristics such as reset delay and accuracy. Confirm package dimensions match existing footprints.
