MAX6327XR30

Overview

The MAX6327XR30 is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of up to 5.5 V and features a threshold voltage of 3 V. The device provides an active high, push-pull output with a reset delay time of 280 ms. It consumes a working power current of 500 nA and has an overvoltage threshold of 2.537 V. The component supports a maximum power dissipation of 174 mW and functions in temperatures from -40 C to +85 C. It is housed in a SC-70-3 package.

Feature Summary

• Provides voltage supervision with an active high, push-pull output configuration
• Operates at ultra-low quiescent current for extended battery life
• Includes internal reset timer for reliable power-up sequencing

Applications

• Portable electronic devices requiring low-power monitoring
• Battery-operated systems needing voltage supervision
• Microprocessor reset circuits in embedded applications

Procurement Notes

Verify the exact suffix and manufacturer documentation before procurement. Confirm availability status as distribution channels may indicate limited stock or discontinuation. Ensure the SC-70-3 package matches your PCB footprint requirements. Check RoHS compliance details against specific project standards. Validate the 3 V threshold specification against your system's operating voltage.

Selection Notes

Select this component when an active high output is required for logic compatibility. Consider the 280 ms reset delay for timing-sensitive applications. Evaluate the 500 nA current consumption against strict power budgets. Ensure the 5.5 V maximum input rating exceeds your system's peak voltage. Verify that the SC-70-3 package fits your spatial constraints.

Part Context

This part belongs to the MAX6327X series of uPower Reset Circuits. It is designed for applications requiring minimal current draw while maintaining accurate voltage monitoring. The series offers various threshold options to suit different supply rails. It integrates essential reset functionality without external components.

Replacement Considerations

Check for MAX6327 variants with different thresholds or packages. Compare electrical specifications such as reset delay and current consumption. Verify pinout compatibility if substituting directly. Review manufacturer obsolescence notices for long-term supply assurance.
