MAX6327XR24-T

Overview

The MAX6327XR24-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.2 V to 5.5 V and consumes only 3 µA of supply current at 1.8 V. The device features a fixed threshold voltage of 2.4 V with an accuracy of 2.5%. It provides a reset pulse duration of 280 ms and utilizes a push-pull active-high output. Packaged in a compact SC-70-3 surface-mount format, it supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Monitors power-supply voltages while maintaining ultra-low quiescent current consumption
• Provides precise voltage supervision with guaranteed reset timing for system reliability
• Delivers a stable active-high push-pull reset signal upon power-up or fault detection

Applications

• Portable battery-powered equipment requiring extended battery life
• Handheld instruments and medical devices
• Wireless communication modules and base stations
• Personal digital assistants (PDAs) and mobile phones

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when sourcing. Confirm that the 'R' variant denotes the SC-70 package type distinct from other form factors. Ensure compatibility with the required 2.4 V threshold for the target application voltage rails. Check for RoHS compliance status as indicated in official documentation.

Selection Notes

Select this component when low standby current is critical for battery-operated systems. The fixed 2.4 V threshold suits applications monitoring 3.3 V or 5 V rails where precise supervision is needed without external resistors. The SC-70 package minimizes board space compared to larger packages. Verify that the 280 ms delay meets the startup requirements of the connected microprocessor.

Part Context

This part belongs to the MAX6327X family of low-power voltage supervisors designed for portable electronics. It complements other Maxim Integrated supervisory circuits by offering a balance of minimal current draw and reliable reset generation. The series is engineered to replace discrete supervisor solutions in space-constrained designs.

Replacement Considerations

MAX6327XR24+ is the lead-free equivalent of the same functional specification.
