MAX6326UR29+T

Supervisors Overview

The MAX6326UR29+T 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 threshold voltage of 2.93 V with an accuracy of 2.5%. The device provides an active high, push-pull output and includes a reset delay time of 185 ms. It consumes a typical operating supply current of 1 uA. The component is housed in a SOT-23-3 package and functions across a temperature range from -40 C to +85 C.

Supervisors Feature Summary

• Ultra-low-power consumption suitable for battery-operated applications
• Active high push-pull output configuration
• Fixed threshold voltage supervision without manual reset or watchdog timer

Supervisors Applications

• Portable electronic devices requiring low standby current
• Battery-powered systems needing voltage monitoring
• Embedded controllers requiring power supply supervision

Supervisors Procurement Notes

Verify the specific suffix UR29 confirms the 2.93 V threshold variant. Confirm RoHS compliance status through official documentation. Check availability as distribution channels may indicate limited stock or discontinuation. Ensure the SOT-23-3 package matches your PCB footprint requirements before ordering.

Supervisors Selection Notes

Select this component when an active high output is required for system logic compatibility. The 1 uA quiescent current makes it ideal for energy-constrained designs. Verify that the 2.93 V threshold aligns with the monitored rail's minimum operating voltage. Consider the 185 ms reset delay for timing-sensitive microcontroller initialization sequences.

Supervisors Part Context

This part belongs to the MAX6326U series of ultra-low-power reset circuits. It shares the SOT-23-3 form factor with other variants in the family but differs in threshold voltage and output polarity. The series is designed for compact portable electronics where space and power efficiency are critical constraints.

Supervisors Replacement Considerations

Check for MAX6326URxx+T variants with matching threshold voltages. Verify output polarity compatibility if substituting with active low counterparts like the MAX6325 series. Ensure package and thermal characteristics remain consistent for direct replacement.
