MAX6326XR26+T

Overview

The MAX6326XR26+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 fixed threshold voltage of 4.6 V. The device provides an active low, push-pull output signal with a reset delay time of 185 ms. It is designed for surface mount installation in SC-70-3 packages. The component functions across a temperature range from -40°C to +85°C and maintains an accuracy of 1.5%. It consumes a maximum operating current of 500 nA.

Feature Summary

• Provides automatic power supply monitoring with a fixed threshold detection level
• Delivers a digital reset signal via an active low push-pull output driver
• Ensures system stability through a defined reset timeout period following power-up

Applications

• Microprocessor reset circuits
• Battery-powered equipment supervision
• Portable instrumentation power management

Procurement Notes

Verify the specific suffix 'XR26' to confirm the 4.6V threshold and SC-70 package variant. Confirm RoHS compliance status as indicated in official documentation. Check for obsolescence notices or lifecycle changes prior to finalizing procurement plans.

Selection Notes

Select this component when a fixed 4.6V supervision level is required for systems operating up to 5.5V. The SC-70-3 package suits space-constrained designs. Ensure the 185ms reset delay aligns with the target microcontroller's startup requirements.

Part Context

This part belongs to the MAX6326U series of ultra-low-power reset circuits. It shares the family's core functionality but differs in threshold voltage and packaging compared to other variants like the MAX6326UR23+T. The series targets applications requiring reliable power monitoring with minimal quiescent current consumption.

Replacement Considerations

Cross-reference with MAX6326XR26+TDKR for identical specifications. Verify pinout compatibility with existing PCB layouts before substituting.
