MAX6327UR23+T

Supervisors Overview

The MAX6327UR23+T is a microprocessor supervisory circuit from the MAX6327 series, manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single voltage input with a threshold of 2.3V and an accuracy of 1.5%. The device features an active-high, push-pull reset output and operates within a supply voltage range up to 5.5V. It draws a maximum supply current of 1µA and includes a minimum reset delay time of 100ms. The component functions reliably over a temperature range of -40°C to +85°C and is housed in a SOT-23-3 surface-mount package.

Supervisors Feature Summary

• Provides active-high push-pull reset signal generation for monitored power supplies
• Ultra-low supply current consumption suitable for portable equipment
• Factory-trimmed precision voltage monitoring thresholds
• Ensures correct state operation down to 1V supply voltage

Supervisors Applications

• Microprocessor system power supply supervision
• Digital system voltage monitoring
• Portable equipment power management

Supervisors Procurement Notes

Verify the specific suffix UR23+T against official manufacturer documentation to confirm the exact threshold voltage and output configuration. Ensure compatibility with the target PCB footprint for the SOT-23-3 package. Confirm RoHS compliance status through the latest datasheet or certificate of conformity provided by Analog Devices.

Supervisors Selection Notes

Select this component when an active-high reset signal is required rather than the more common active-low variant. The MAX6327 series is appropriate for designs needing ultra-low quiescent current. Verify that the 2.3V threshold aligns with the specific rail being monitored. Consider the push-pull output capability if driving loads directly without external pull-up resistors is necessary.

Supervisors Part Context

The MAX6327UR23+T belongs to the MAX6326/MAX6327/MAX6328 family of ultra-low-power reset circuits. These devices are designed to eliminate external components and adjustments in 2.5V, 3V, 3.3V, and 5V powered circuits. The MAX6327 variant specifically provides an active-high output, distinguishing it from the active-low MAX6326 and MAX6328 counterparts within the same low-power family.

Supervisors Replacement Considerations

Direct functional substitutes include other MAX6327 variants with different threshold voltages (e.g., MAX6327UR25+T) if the 2.3V threshold is not critical. Cross-series replacements like the MAX6347 offer similar functionality but may differ in package options or specific electrical characteristics.
