MAX6327XR22-T

Overview

The MAX6327XR22-T is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.63V to 5.5V and features a fixed threshold voltage of 2.2V. The device provides an active-low, open-drain reset output with a typical reset delay time of 280ms. It consumes a maximum operating supply current of 500nA and functions reliably across an extended temperature range from -40°C to +85°C. The component is housed in a compact SC-70-3 surface-mount package.

Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Compact three-pin SC-70 surface-mount packaging
• Fixed threshold voltage supervision without manual reset capability

Applications

• Portable electronic devices requiring low standby current
• Battery-powered instrumentation and metering equipment
• Microprocessor system power monitoring

Procurement Notes

Verify the exact suffix against official manufacturer documentation, as variations such as +T indicate specific tape-and-reel packaging configurations. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may be subject to change or limited distribution constraints.

Selection Notes

Select this component when a fixed 2.2V threshold is required for single-supply monitoring. Ensure the open-drain output configuration aligns with the pull-up requirements of the connected logic interface. Verify that the 280ms reset delay meets the timing specifications of the target microcontroller or system startup sequence.

Part Context

This part belongs to the MAX6327X family of uPower Reset Circuits designed for low-voltage applications. The series offers various threshold options and package styles to accommodate different design constraints while maintaining minimal quiescent current draw.

Replacement Considerations

Consult the official MAX6327 datasheet for confirmed pin-compatible alternatives within the same product family that offer different threshold voltages or package types.
