MAX6327XR22+T

Overview

The MAX6327XR22+T is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.2 V to 5.5 V and features a fixed threshold voltage of 2.2 V. 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 1 µA and functions reliably across an industrial temperature range from -40°C to +85°C. The component is housed in a compact SC-70-3 surface-mount package.

Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Compact three-terminal SC-70 surface-mount packaging
• Fixed threshold voltage detection for specific rail monitoring

Applications

• Portable handheld devices requiring minimal quiescent current
• Battery-powered instrumentation and measurement equipment
• Embedded microcontroller system supervision

Procurement Notes

Verify the exact suffix against official manufacturer documentation to confirm pinout compatibility and electrical tolerances. Confirm RoHS compliance status through authorized channels. Ensure the source document matches the specific part number variant to avoid functional mismatches due to minor manufacturing revisions or regional regulatory differences.

Selection Notes

Select this component when a fixed 2.2 V threshold is required for single-rail monitoring. Consider the open-drain output configuration for level shifting requirements. Evaluate the 1 µA supply current against strict power budget constraints. Verify that the SC-70-3 footprint aligns with existing board layout specifications.

Part Context

This part belongs to the MAX6327X series of ultra-low-power reset circuits. The series offers various fixed threshold voltages to accommodate different logic families and supply rails. These components are designed for applications where space and power efficiency are critical constraints.

Replacement Considerations

Cross-reference with other MAX6327 variants sharing the same SC-70-3 package and 2.2 V threshold. Verify equivalent electrical characteristics such as reset delay and supply current before substitution.
