MAX6326UR22+T

Supervisors Overview

The MAX6326UR22+T is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.1V to 5.5V and features a fixed reset threshold voltage of 2.2V. The device provides a low-active push-pull/totem pole output with a typical reset timeout delay of 140ms. It is designed for ultra-low-power applications, consuming minimal current during operation. The component is housed in a compact 3-pin SC70 or SOT-23 package, suitable for surface-mount installation across an industrial temperature range.

Supervisors Feature Summary

• Ultra-low power consumption design optimized for battery-operated systems
• Fixed 2.2V reset threshold ensures precise voltage monitoring
• Compact 3-pin SC70/SOT-23 package for space-constrained layouts

Supervisors Applications

• Portable electronic devices requiring extended battery life
• Microprocessor system supervision
• Battery-powered instrumentation

Supervisors Procurement Notes

Verify the exact suffix UR22 against official datasheets to confirm the 2.2V threshold specification. Ensure compatibility with the target PCB footprint for the 3-pin SC70 or SOT-23 package. Confirm that the low-active output logic aligns with the connected microcontroller input requirements. Check for any specific environmental certifications required for the end application.

Supervisors Selection Notes

Select this component when a fixed 2.2V threshold is required for voltage supervision. Consider the ultra-low power profile if battery longevity is critical. Verify that the 140ms timeout delay meets the system's startup timing constraints. Ensure the operating voltage range covers the minimum and maximum supply voltages of the target circuit.

Supervisors Part Context

This part belongs to the MAX6326 series of supervisory circuits from Maxim Integrated, now part of Analog Devices. The series focuses on providing reliable power management solutions with minimal quiescent current. The UR22 variant specifically denotes the 2.2V threshold version within this family, utilizing standard small-outline packaging for integration into modern electronic designs.

Supervisors Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure replacement parts match the 2.2V threshold, 3-pin package, and low-active output polarity.
