MAX6348XR41-T

Overview

The MAX6348XR41-T is a 3-pin, ultra-low-power microprocessor reset circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range up to 5.5 V and features an overvoltage threshold of 3.958 V. The device provides a single monitored input with an active low, open-drain output type. Key electrical parameters include a reset delay time of 280 ms and a typical operating supply current of 500 nA. It is designed for surface mount installation in SC-70-3 packages.

Feature Summary

• Ultra-low power consumption suitable for battery-operated applications
• Integrated overvoltage detection capability
• Compact SC-70-3 surface-mount package design

Applications

• Monitoring main supply rails in portable electronic devices
• Voltage supervision in embedded systems requiring low quiescent current
• Reset generation for microprocessors and digital logic circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm RoHS compliance details and specific lot traceability requirements before procurement. Check for obsolete status indicators as the part may be subject to discontinuation or limited factory orders. Ensure packaging specifications match production line requirements.

Selection Notes

Select this component when a single-channel supervisor with overvoltage protection is required. The 3.958 V threshold suits applications monitoring 5 V or lower rails. Consider the 500 nA current draw for strict power budget constraints. Verify that the SC-70-3 footprint aligns with existing PCB layouts. Ensure the active low open-drain output interface matches the target system's reset input requirements.

Part Context

This part belongs to the MAX6348 series of uPower Reset Circuits. The series offers various threshold voltages and package options. The XR41 suffix specifically denotes the 4.1 V threshold variant within the broader family. These components are designed for reliable operation across industrial temperature ranges.

Replacement Considerations

Cross-reference with other MAX6348 variants such as MAX6348XR39+T for different threshold requirements. Verify pinout compatibility and electrical characteristics against alternative supervisors from the same manufacturer. Ensure functional equivalence regarding reset delay and output configuration.
