LM3724IM5X-4.63

Supervisors Overview

The LM3724IM5X-4.63 is a microprocessor reset circuit from Texas Instruments designed for monitoring power supply voltages. It features an active low/open drain output and operates within a supply voltage range of 1V to 5.5V. The device provides a specific reset threshold of 4.63V, making it suitable for supervising 5.0V systems. It includes a manual reset input and draws a quiescent current of 8µA. Packaged in a 5-pin SOT-23 tape and reel configuration, this component ensures reliable system initialization and recovery.

Supervisors Feature Summary

• Provides precise voltage supervision with a fixed 4.63V reset threshold
• Features an active low or open drain output for flexible interface compatibility
• Includes a manual reset input capability for external control
• Operates with low quiescent current consumption of 8µA

Supervisors Applications

• Supervising 5.0V power supplies in embedded systems
• Microprocessor reset circuits requiring low power consumption
• Electronic systems needing reliable voltage monitoring and recovery

Supervisors Procurement Notes

Verify the exact suffix and package type when ordering, as availability may vary by region. Confirm that the 4.63V threshold matches your system's 5.0V rail requirements. Check for discontinued status or substitute recommendations from the manufacturer if direct procurement is unavailable. Ensure the SOT-23-5 tape and reel format aligns with your assembly equipment specifications.

Supervisors Selection Notes

Select this component when a fixed 4.63V threshold is required for 5.0V system supervision. Consider the low 8µA quiescent current for battery-sensitive applications. The open drain output allows for wired-OR configurations. Verify compatibility with the system's manual reset logic if external reset control is needed. Ensure the SOT-23-5 package fits the available PCB footprint.

Supervisors Part Context

This part belongs to the LM372x family of 5-pin microprocessor reset circuits, which also includes variants with different reset thresholds such as 3.08V and 2.32V. These devices are designed for low-power applications and offer consistent performance across the series. The LM3724 specifically targets 5.0V supply monitoring, distinguishing it from other members of the family optimized for lower voltage rails like 3.3V or 2.5V.

Supervisors Replacement Considerations

The LM3724IM5-4.63/NOPB is listed as a parametric equivalent substitute. Verify pinout and electrical characteristics match before replacement. Other LM372x variants with different thresholds are not direct substitutes unless the reset voltage requirement changes.
