MAX6348XR46+T

Overview

The MAX6348XR46+T is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1 V to 5.5 V and features a fixed threshold voltage of 4.6 V. The device provides an active low, open-drain output with a reset delay time of 280 ms. It consumes a maximum operating supply current of 500 nA and maintains an accuracy of 1.5%. The component is housed in a SC-70-3 package and supports surface mount installation. It functions without manual reset, watchdog timer, or battery backup switch capabilities.

Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Fixed threshold voltage monitoring for precise supervision
• Compact three-pin surface-mount packaging

Applications

• Portable electronic devices requiring voltage supervision
• Battery-powered instrumentation systems
• Microprocessor reset circuits in compact embedded designs

Procurement Notes

Verify the specific suffix 'XR46' against official datasheets to confirm the 4.6 V threshold and SC-70-3 package configuration. Ensure compatibility with existing PCB footprints and voltage levels. Confirm availability status through authorized distributors as supply conditions may vary. Cross-reference part numbers carefully to avoid mismatches in threshold voltages or package types.

Selection Notes

Select this component when a fixed 4.6 V threshold is required for system supervision. Consider the SC-70-3 package size for space-constrained applications. Evaluate the 500 nA quiescent current against total system power budgets. Verify that the active low open-drain output aligns with downstream logic requirements. Compare against other MAX6348 variants if different thresholds or packages are needed.

Part Context

This part belongs to the MAX6348 family of ultra-low-power microprocessor reset circuits. The series offers various threshold voltages and package options to suit diverse design needs. Analog Devices acquired Maxim Integrated, integrating these products into their portfolio. The family is designed for reliable voltage monitoring in portable and industrial applications.

Replacement Considerations

The ADM6348-34ARTZ-R7 is a related variant from the same manufacturer family. Verify pinout compatibility and threshold voltage differences before substitution. Check for any changes in package dimensions or electrical characteristics.
