MAX6326UR31+T

Supervisors Overview

The MAX6326UR31+T is a 3-pin, ultra-low-power microprocessor reset 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 3.08V. The device provides an active low, push-pull output with a typical reset delay time of 185 ms. It consumes only 500 nA of quiescent current and maintains an accuracy of 1.5%. The component is housed in a SOT-23-3 package and functions without manual reset or watchdog timer capabilities.

Supervisors Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Fixed threshold voltage monitoring for specific supply rails
• Compact 3-pin surface-mount packaging

Supervisors Applications

• Microprocessor power supply supervision
• Battery-powered portable electronics
• Embedded system reset control

Supervisors Procurement Notes

Verify the exact suffix (+T) against the manufacturer's official datasheet to confirm tape-and-reel packaging and RoHS compliance status. Ensure the 3.08V threshold matches your design requirements before ordering, as this variant is distinct from other threshold options in the MAX6326 family. Confirm availability through authorized distributors due to potential limited stock situations.

Supervisors Selection Notes

Select this part when a fixed 3.08V supervision level is required for low-voltage digital circuits. The ultra-low 500 nA current draw makes it ideal for energy-constrained applications where standby power is critical. Verify that the 185 ms reset delay meets the timing requirements of the target processor or logic components during power-up sequences.

Supervisors Part Context

This component belongs to the MAX6326U series of simple reset circuits designed for monitoring single power supplies. It serves as a fundamental building block for ensuring reliable system startup and recovery from brown-out conditions in compact electronic designs requiring minimal board space and power.

Supervisors Replacement Considerations

Consider MAX6326UR23+T for lower threshold applications (2.32V). Other variants in the MAX6326 family offer different fixed thresholds such as 2.63V or 4.63V depending on specific voltage rail requirements while maintaining identical package and performance characteristics.
