MAX6327UR22+T

Supervisors Overview

The MAX6327UR22+T is a microprocessor supervisory circuit designed for portable equipment. It monitors a single voltage input with a threshold of 2.2 V. The device features an active-high, push-pull output and operates within a supply range of 1 V to 5.5 V. It draws a maximum supply current of 1 µA. The reset delay time is 185 ms, with an accuracy of 1.5%. It functions in temperatures from -40°C to +85°C and is housed in an SOT-23-3 package.

Supervisors Feature Summary

• Ultra-low power consumption suitable for battery-operated devices
• Active-high push-pull output interface
• Precision voltage monitoring with factory-trimmed thresholds

Supervisors Applications

• Portable electronic equipment
• Microprocessor system supervision
• Digital system power monitoring

Supervisors Procurement Notes

Verify the exact suffix UR22 to confirm the 2.2 V threshold specification. Ensure compatibility with active-high logic requirements. Confirm RoHS compliance status through official manufacturer documentation before integration into final designs.

Supervisors Selection Notes

Select this component when an active-high reset signal is required. Compare against open-drain variants like the MAX6328 if pull-up resistors are undesirable. Verify that the 2.2 V threshold aligns with the monitored rail's minimum operating voltage.

Supervisors Part Context

This part belongs to the MAX6327 family of ultra-low-power reset circuits. It shares architectural similarities with the MAX6326 and MAX6328 but differs in output stage configuration. The series is designed to eliminate external components in standard 2.5V, 3V, 3.3V, and 5V powered circuits.
