MAX6348XR33+

Overview

The MAX6348XR33+ is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range up to 5.5 V and features an active low, open-drain output type. The device monitors a single input with a threshold voltage of 3.3 V and provides a reset delay time of 280 ms. It functions without manual reset or watchdog timer capabilities. The component supports surface mount installation in an SC-70-3 package and operates across a temperature range from -40 C to +85 C.

Feature Summary

• Ultra-low-power operation suitable for battery-supplied systems
• Compact three-pin packaging for space-constrained designs
• Fixed threshold voltage monitoring for specific rail supervision

Applications

• Portable electronic devices requiring power management
• Battery-operated instrumentation systems
• Embedded controllers needing voltage supervision

Procurement Notes

Verify availability status as distribution channels may indicate limited stock or discontinuation. Confirm exact ordering suffixes match required threshold voltages and packages. Check RoHS compliance documentation for regulatory requirements. Validate supplier authenticity through authorized distributor networks. Review datasheet revisions for potential design-in updates.

Selection Notes

Select this component when fixed 3.3 V monitoring is required without adjustable thresholds. Consider the SC-70-3 package for minimal board area consumption. Evaluate power consumption constraints against the ultra-low quiescent current specification. Ensure system voltage never exceeds the maximum operating limit of 5.5 V. Verify thermal performance within the specified industrial temperature range.

Part Context

This part belongs to the MAX6348 series of microprocessor reset circuits designed for low-power applications. The series offers various threshold options packaged in small form factors. Analog Devices acquired Maxim Integrated, integrating these legacy product lines into their portfolio. The component serves as a dedicated supervisor for digital logic systems.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family offering different threshold voltages. Verify if newer generations provide improved accuracy or lower power consumption. Confirm package dimensions match existing footprints before substitution.
