MAX6327XR31+T

Overview

The MAX6327XR31+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single voltage input and provides an active-high, push-pull reset output when the supply voltage declines below a preset threshold of 3.08 V. The device operates within a power supply range of 1.2 V to 5.5 V and features a typical reset delay time of 280 ms. It draws a maximum operating supply current of 500 nA. The component is housed in a SC-70-3 package and is rated for operation between -40°C and +85°C.

Feature Summary

• Provides active-high push-pull reset signal generation upon undervoltage detection
• Ultra-low power consumption suitable for portable equipment applications
• Factory-trimmed reset thresholds ensure precise monitoring without external adjustments

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices. Ensure the SC-70-3 package matches design requirements. Validate that the specific threshold voltage meets system specifications before procurement.

Selection Notes

Select this component for applications requiring low quiescent current and compact packaging. The active-high output suits logic interfaces requiring high-level reset signals. Verify that the 3.08 V threshold aligns with the monitored rail. Consider thermal performance within the specified industrial temperature range during integration.

Part Context

This part belongs to the MAX6327X series of ultra-low-power reset circuits. These devices eliminate external components by integrating precision comparators and timers. The series offers various factory-set thresholds for standard voltage rails, simplifying design for systems powered by 2.5V, 3V, 3.3V, and 5V supplies.

Replacement Considerations

Cross-reference with other MAX6327 variants having identical pinouts and active-high outputs. Verify threshold voltage compatibility with the target application. Check package dimensions for mechanical fit.
