MAX6327XR26+

Overview

The MAX6327XR26+ is a single-channel power supply support circuit manufactured by Analog Devices Inc. It operates within an extended temperature range of -40°C to +85°C and utilizes a lead-free SC-70 package with three pins. The device features a fixed threshold voltage of 2.63 V and an overvoltage threshold of 2.669 V. It provides a reset delay time of 185 ms and maintains an accuracy of 1.5%. The maximum operating supply voltage is 5.5 V, with a typical power dissipation of 174 mW.

Feature Summary

• Provides precise voltage supervision for single-channel power rails
• Ensures system stability through defined reset delay timing
• Operates reliably across industrial temperature ranges

Applications

• Portable electronic devices requiring low-power monitoring
• Battery-operated equipment needing voltage supervision
• Industrial control systems utilizing standard logic levels

Procurement Notes

Verify the specific suffix and manufacturer documentation to confirm exact electrical characteristics and pinout compatibility before integration. Ensure that the selected component matches the required threshold voltage and package type for your specific design constraints. Cross-reference official datasheets to validate performance parameters against your application requirements.

Selection Notes

Select this component when a fixed threshold voltage near 2.63 V is required for single-supply monitoring. Consider the SC-70 package size for space-constrained designs. Evaluate the 185 ms reset delay to ensure it aligns with system startup timing requirements. Verify that the 5.5 V maximum supply rating covers the intended operating voltage range.

Part Context

This part belongs to the MAX6327X series of ultra-low-power reset circuits. It is designed for applications where minimal current consumption and compact packaging are critical. The series offers various threshold voltages to accommodate different supply rail monitoring needs in portable and battery-powered electronics.

Replacement Considerations

Check for MAX6327 variants with different threshold voltages or packages if the 2.63 V setting does not match the target rail. Verify pinout compatibility with alternative suppliers offering similar supervisory circuits.
