MAX6327XR30-T

Overview

The MAX6327XR30-T is a microprocessor supervisory circuit from Analog Devices Inc./Maxim Integrated, designed to monitor power supplies in digital systems. It provides an active-high push-pull reset signal when the supply voltage declines below a preset threshold. The device operates with ultra-low supply currents of 500 nA and supports input voltages up to 5.5 V. It features a fixed 2.5 V overvoltage threshold and a 280 ms reset delay time. The component is housed in a compact SC-70-3 package and functions reliably within a temperature range of -40°C to +85°C.

Feature Summary

• Provides active-high push-pull reset output for reliable system supervision
• Ultra-low power consumption suitable for portable equipment applications
• Compact SC-70-3 surface-mount packaging for space-constrained designs

Applications

• Microprocessor power supply monitoring
• Portable digital system supervision
• Battery-powered device protection

Procurement Notes

Verify availability status as distribution channels may indicate limited stock or discontinuation. Confirm RoHS compliance details through official manufacturer documentation before procurement. Ensure the specific suffix matches design requirements for voltage thresholds and package types. Cross-reference ordering information with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component for applications requiring low quiescent current and active-high reset logic. Verify that the 2.5 V threshold aligns with the monitored rail's minimum operating voltage. Consider the 280 ms delay for system startup timing requirements. Ensure the SC-70-3 package fits the PCB layout constraints.

Part Context

This part belongs to the MAX6327X series of uPower Reset Circuits. It shares functional similarities with other members like the MAX6326 and MAX6328 but differs in output polarity and specific threshold configurations. The series is designed to eliminate external components for basic voltage supervision tasks.

Replacement Considerations

Check for direct pin-compatible substitutes within the MAX6326/MAX6327/MAX6328 family. Verify if alternative manufacturers offer equivalent active-high supervisors with similar current consumption and package dimensions.
