LM3724IM5-2.32/NOPB

Supervisors Overview

The LM3724IM5-2.32/NOPB is a processor supervisor circuit manufactured by Texas Instruments, formerly National Semiconductor. It provides a single active-low/open-drain reset signal triggered at a fixed threshold voltage of 2.32V. The device operates within an extended temperature range of -40°C to +125°C and is housed in a compact 5-pin SOT-23 package. This component ensures reliable system initialization by monitoring supply voltages and generating reset pulses during power-up or brown-out conditions.

Supervisors Feature Summary

• Generates a reset signal when the monitored supply voltage drops below the specified threshold
• Features an active-low output with open-drain capability for flexible logic interfacing
• Includes internal delay circuits to prevent false resets during power transitions

Supervisors Applications

• Microprocessor and microcontroller power supply supervision
• Battery-powered systems requiring low-voltage detection
• Embedded control units needing reliable startup sequencing

Supervisors Procurement Notes

Verify the manufacturer designation as Texas Instruments, which acquired National Semiconductor. Confirm the specific threshold voltage suffix matches the required 2.32V level. Ensure the package type corresponds to the 5-pin SOT-23 form factor. Check for RoHS compliance status indicated by the NOPB suffix. Validate that the operating temperature range meets the application's environmental requirements.

Supervisors Selection Notes

Select this component when a fixed 2.32V threshold is required for system supervision. Consider the open-drain output configuration for compatibility with various logic families. Evaluate the SOT-23 package size against available PCB space constraints. Ensure the extended industrial temperature range aligns with the deployment environment. Compare performance characteristics against other members of the LM3724 family if alternative thresholds are needed.
