MAX6326UR28-T

Supervisors Overview

The MAX6326UR28-T is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.2V to 5.5V and features a fixed threshold voltage of 2.8V with an accuracy of 1.5%. The device provides an active-low, open-drain reset output with a typical reset delay time of 185ms. It consumes only 500nA of operating current and functions reliably across an industrial temperature range of -40°C to +85°C. Packaged in a compact SOT-23-3 surface-mount case, it monitors a single input without manual reset or watchdog timer capabilities.

Supervisors Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Compact three-pin surface-mount packaging for space-constrained designs
• Guaranteed valid reset signals down to 1V supply voltage

Supervisors Applications

• Microprocessor power supply monitoring
• Battery-powered portable electronics
• Handheld communication devices

Supervisors Procurement Notes

Verify the exact suffix against official documentation, as standard listings often use MAX6326UR28+T. Confirm availability status directly with authorized distributors, as this component may be subject to limited supply or discontinuation. Ensure the ordering information matches the specific package and electrical characteristics required for your design implementation.

Supervisors Selection Notes

Select this component when a low-power supervisor with an open-drain output is required. Verify that the 2.8V threshold aligns with the monitored rail. Consider the SOT-23-3 footprint constraints and ensure the open-drain configuration allows for proper pull-up resistor selection in the target application circuit.

Supervisors Part Context

This part belongs to the MAX6326U series of ultra-low-power reset circuits. It shares the family's core architecture but differs in threshold voltage and output stage compared to variants like the push-pull MAX6326UR28+ or other threshold options within the same package type.

Supervisors FAQ

Does the MAX6326UR28-T include a manual reset input?
