LM3724EM5-2.32/NOPB

Supervisors Overview

The LM3724EM5-2.32/NOPB is a voltage supervisory circuit manufactured by Texas Instruments, belonging to the SolarMagic series. It operates within an extended temperature range of -40°C to +125°C and utilizes a SOT-23-5 surface-mount package. The device monitors a single input voltage with a threshold set at 2.32V. It provides an active-low/open-drain reset output and includes a manual reset function. The component supports power supply supervision and processor reset applications in compact designs.

Supervisors Feature Summary

• Integrates a manual reset button for user-initiated system resets alongside automatic power-on reset capabilities.
• Features an open-drain active-low reset output compatible with various logic families.
• Designed for low-power operation suitable for battery-supervised systems.

Supervisors Applications

• Microprocessor reset circuits
• Battery-powered system supervision
• Portable electronic devices

Supervisors Procurement Notes

Verify the specific suffix '2.32' to confirm the exact voltage threshold matches the design requirement. Confirm the 'EM5' designation corresponds to the SOT-23-5 package variant. Check current lifecycle status as some variants may be recommended against new designs. Ensure RoHS compliance documentation is available for regulatory requirements.

Supervisors Selection Notes

Select this component when a precise 2.32V monitoring threshold is required for low-voltage systems. Consider the SOT-23-5 package size constraints and the need for manual reset functionality. Evaluate the operating temperature range suitability for the intended environment compared to other thresholds in the LM3724 family.

Supervisors Part Context

This part is part of the LM3724 family of simple reset circuits from Texas Instruments. It shares functional similarities with other members like the LM3723 and LM3724 but differs in specific threshold voltages and package options. The SolarMagic branding indicates optimization for low-power applications.

Supervisors Replacement Considerations

LM3724EM5-3.08/NOPB: Different threshold voltage (3.08V vs 2.32V). LM3724EM5-4.63/NO: Different threshold voltage (4.63V vs 2.32V). Verify pinout compatibility if substituting with non-TI equivalents.
