MAX6448UK31L

Supervisors Overview

The MAX6448UK31L is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within an extended temperature range of -40°C to +85°C and utilizes a SOT-23-5 surface-mount package. The device monitors a single supply voltage with a fixed threshold of 3.075V. It features one delayed manual reset input and one immediate manual reset input, providing flexibility in system control. The RESET output is active-low and available in push-pull or open-drain configurations. The typical reset timeout period is 210ms, ensuring stable system recovery after power events.

Supervisors Feature Summary

• Integrates dual manual reset inputs for distinct delayed and immediate system control capabilities
• Provides precision factory-set reset thresholds for reliable voltage supervision
• Features active-low reset output with selectable push-pull or open-drain logic options

Supervisors Applications

• Microprocessor power supply monitoring in industrial systems
• Embedded controller reset generation for portable electronics
• Battery-powered equipment requiring low-current supervision

Supervisors Procurement Notes

Verify component authenticity through authorized distribution channels due to potential counterfeit risks. Confirm RoHS compliance status and specific manufacturing lot dates against current datasheet revisions. Check for obsolescence notices as this series may be subject to discontinuation. Ensure packaging specifications match design requirements for automated assembly processes.

Supervisors Selection Notes

Evaluate the necessity for both delayed and immediate manual reset functions compared to simpler single-input variants. Consider the fixed 3.075V threshold suitability for the target supply rail. Assess if the SOT-23-5 package dimensions fit the mechanical constraints. Compare supply current consumption against other low-power supervisor alternatives for battery life optimization.

Supervisors Part Context

This component belongs to the MAX6443–MAX6452 family of low-current microprocessor reset circuits. These devices are designed to monitor supply voltages and generate reset signals for digital systems. The family offers various combinations of manual reset inputs and output types to accommodate different system architectures and safety requirements.

Supervisors Replacement Considerations

Consider MAX6445UK31L+T or MAX6446UK16L+T as potential functional substitutes within the same product family. Verify that alternative part numbers maintain compatible threshold voltages and output drive capabilities. Ensure pinout compatibility to facilitate direct board-level replacement without redesigning the footprint.
