MAX6326UR22

Supervisors Overview

The MAX6326UR22 is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of up to 5.5 V and features a fixed threshold voltage of 2.2 V. The device provides an active low, push-pull reset output with a reset delay time of 185 ms. It has an accuracy of 1.5% and consumes a working power supply current of 500 nA. The component is housed in a SOT-23-3 package and functions within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Ultra-low-power operation with 500 nA quiescent current
• Fixed threshold voltage supervision for single-channel monitoring
• Active low push-pull reset output generation
• Compact SOT-23-3 surface-mount packaging

Supervisors Applications

• Portable battery-powered equipment
• Microcontroller system power monitoring
• Embedded controller reset circuits
• Battery backup switching systems

Supervisors Procurement Notes

Verify the specific suffix 'UR22' against official datasheets to confirm the 2.2V threshold variant. Check manufacturer lifecycle status as some variants may be discontinued or subject to limited supply constraints. Ensure compatibility with existing PCB footprints and thermal requirements before integration.

Supervisors Selection Notes

Select this component when a fixed 2.2V threshold is required for precise voltage monitoring. Consider the 185ms reset delay and 1.5% accuracy for timing-sensitive applications. Evaluate the ultra-low power consumption benefits for battery-operated designs compared to higher current alternatives.

Supervisors Part Context

The MAX6326 series belongs to Maxim Integrated's line of ultra-low-power reset circuits. These devices are designed to monitor voltage levels in portable and battery-powered applications. The UR22 variant specifically targets systems requiring a 2.2V supervision threshold within a compact footprint.

Supervisors Replacement Considerations

Public confirmed substitute part numbers: MAX6326UR23+T (2.32V threshold), MAX6326UR25+T (2.50V threshold). Verify threshold voltage compatibility before substitution.
