MAX6326UR27+T

Supervisors Overview

The MAX6326UR27+T is a voltage supervisory circuit from the MAX6326U series, 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 2.7 V with an accuracy of 1.5%. The device provides an active-low, open-drain reset output with a typical reset delay time of 185 ms. It consumes a maximum operating supply current of 500 nA and is housed in a 3-pin SOT-23 package. The component functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Ultra-low-power consumption suitable for battery-operated systems
• Fixed threshold voltage monitoring for single-input supervision
• Active-low open-drain reset output configuration

Supervisors Applications

• Portable electronic devices requiring low standby current
• Battery-powered instrumentation systems
• Microprocessor and microcontroller power supply monitoring

Supervisors Procurement Notes

Verify availability status as distribution channels may indicate limited stock or obsolete status. Confirm RoHS compliance details through official manufacturer documentation. Ensure the specific suffix matches design requirements. Cross-reference datasheet revisions for any parameter updates before finalizing procurement orders.

Supervisors Selection Notes

Select this component when an open-drain output is required for wired-OR configurations or level shifting. The 2.7 V threshold suits 3.3 V logic systems. Verify that the 185 ms delay meets system startup timing constraints. Ensure the SOT-23 package fits the PCB layout constraints.

Supervisors Part Context

This part belongs to the MAX6326 family of ultra-low-power reset circuits. It shares core architecture with variants offering different thresholds and push-pull outputs. The 'U' indicates the SOT-23 package, while '+T' denotes tape-and-reel packaging. It serves as a dedicated voltage supervisor for digital logic protection.

Supervisors Replacement Considerations

Check for MAX6326UR27-T if available, noting potential obsolescence differences. Consider MAX6328UR27+T for similar threshold but verify output type compatibility. Review MAX6326UR23+T for lower threshold applications.
