MAX6327XR23

Overview

The MAX6327XR23+T is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.2V to 5.5V and features a fixed reset threshold of 2.32V. The device provides an active-high, push-pull output signal. Key electrical parameters include a maximum operating supply current of 1µA, a reset delay time of 280ms, and a power dissipation rating of 174mW. It is housed in a compact SC-70-3 surface-mount package and supports operation across a temperature range of -40°C to +85°C.

Feature Summary

• Ultra-low power consumption with a maximum supply current of 1µA
• Active-high push-pull reset output configuration
• Compact SC-70-3 surface-mount packaging for space-constrained designs

Applications

• Portable electronic equipment requiring extended battery life
• Microprocessor (µP) and digital system power supply monitoring
• Battery-powered devices utilizing 2.5V, 3V, or 3.3V logic levels

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific manufacturing date codes relevant to your project requirements. Ensure the SC-70-3 package variant matches your PCB footprint specifications before finalizing procurement orders.

Selection Notes

Select this component when an active-high reset signal is required for systems powered by 2.32V thresholds. It is suitable for applications prioritizing low quiescent current over manual reset capabilities. Consider alternative models if open-drain outputs or watchdog timer integration are necessary for the specific design constraints.

Part Context

This part belongs to the MAX6327X series of microprocessor supervisory circuits designed for ultra-low-power applications. It shares functional similarities with the MAX6326 and MAX6328 but differs in output polarity and drive type. The series eliminates external components for standard voltage monitoring tasks in portable digital systems.

Replacement Considerations

The MAX6327XR26+T serves as a verified substitute within the same family, offering identical functionality with a different reset threshold voltage.
