LM3724IM5-4.63/NOPB

Supervisors Overview

The LM3724IM5-4.63/NOPB is a processor supervisor circuit manufactured by Texas Instruments, designed to monitor voltage levels and generate reset signals for microprocessors. It features a single monitored input with a fixed threshold of 4.63V. The device provides one active low/open drain output and operates within an extended temperature range from -40°C to +125°C. Packaged in a compact 5-pin SOT-23 format, it ensures reliable system supervision in space-constrained applications requiring precise voltage monitoring.

Supervisors Feature Summary

• Provides dedicated processor supervision with a fixed voltage threshold
• Generates active low reset signals via open-drain output
• Operates reliably across extended industrial temperature ranges

Supervisors Applications

• Microprocessor power supply monitoring
• Embedded system voltage supervision
• Industrial control board reset circuits

Supervisors Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct threshold voltage and package type. Confirm availability status as component lifecycles may change. Cross-reference ordering information with authorized distributors to avoid counterfeit parts. Ensure compliance with RoHS directives if required by your application standards.

Supervisors Selection Notes

Select this component when a fixed 4.63V threshold is required for system supervision. Consider the SOT-23-5 package for space-limited designs. Evaluate the active low output polarity against the target microprocessor reset requirements. Verify that the operating temperature range meets the environmental conditions of the final assembly.

Supervisors Part Context

This part belongs to the LM3724 series of supervisory circuits from Texas Instruments. It is functionally related to other variants in the family that offer different voltage thresholds or output configurations. The series is designed for general-purpose voltage monitoring in digital systems.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the LM372x family with matching 4.63V thresholds. Verify equivalent electrical characteristics such as reset timeout and quiescent current before substitution.
