MAX6327UR30-T

Overview

The MAX6327UR30-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors power supply voltages and asserts an active-high, push-pull reset signal when the input voltage drops below a fixed threshold of 3V. The device features ultra-low supply current, typically 1µA maximum, making it suitable for portable applications. It provides a minimum power-on reset pulse width of 100ms and operates within a temperature range of -40°C to +85°C. The component is housed in a compact SOT-23-3 surface-mount package.

Feature Summary

• Provides active-high push-pull reset output for reliable logic interfacing
• Ultra-low supply current consumption ideal for battery-powered systems
• Fixed threshold monitoring eliminates external resistor adjustments
• Compact three-pin surface-mount packaging for space-constrained designs

Applications

• Portable electronic equipment requiring low standby current
• Microprocessor and digital system power supply supervision
• Battery-operated devices with strict power management needs
• Embedded systems utilizing 3V logic levels

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates. Ensure the active-high output variant matches system logic requirements, as other MAX6327 variants offer different output types. Cross-reference the exact part number against the latest datasheet revision to confirm pinout and electrical specifications.

Selection Notes

Select this component when an active-high reset signal is required rather than the open-drain or push-pull active-low alternatives found in the MAX6326/MAX6328 series. The fixed 3V threshold suits systems powered directly by 3V sources without needing adjustable divider networks. Consider the ultra-low quiescent current for applications where battery life is critical. Verify that the SOT-23-3 footprint aligns with existing PCB layout constraints.

Part Context

This component belongs to the MAX632x family of microprocessor supervisory circuits designed for cost-effective reliability. These devices eliminate external components by integrating precision comparators and timers. The MAX6327 specifically offers an active-high output, distinguishing it from the active-low variants in the same series. The family supports standard voltage rails including 2.5V, 3V, 3.3V, and 5V systems.
