LM3722IM5-4.63/NOPB

Supervisors Overview

The LM3722IM5-4.63/NOPB is a single-channel voltage supervisor manufactured by Texas Instruments, housed in a SOT-23-5 surface-mount package. It features a fixed output threshold of 4.63V and provides an active-low reset signal via a push-pull or图腾柱 output stage. The device ensures system reliability with a minimum reset timeout of 100ms. It operates within a temperature range of -40°C to +85°C and supports simple reset and power-on reset functions.

Supervisors Feature Summary

• Provides active-low reset signal generation for monitored voltage rails
• Features a push-pull output stage for robust drive capability
• Includes internal circuitry for simple reset and power-on reset sequences

Supervisors Applications

• Embedded systems requiring voltage supervision
• Microcontroller power management circuits
• Industrial control board monitoring

Supervisors Procurement Notes

Verify component authenticity through authorized distributors as the part status is listed as obsolete. Confirm package integrity and pin alignment against the SOT-23-5 specification. Check for RoHS compliance documentation if required for specific regulatory standards. Ensure storage conditions maintain moisture sensitivity level 1 integrity prior to soldering.

Supervisors Selection Notes

Select this component when a fixed 4.63V threshold is required for system supervision. Consider the SOT-23-5 package size constraints for PCB layout. Evaluate the 100ms minimum reset timeout against system startup requirements. Verify that the active-low output polarity matches the receiving logic interface design.

Supervisors Part Context

This device belongs to the LM3722 family of voltage supervisors from Texas Instruments. It shares functional similarities with other members like the LM3724 series but differs in specific threshold voltages and output configurations. The NOPB suffix indicates lead-free construction compliant with environmental directives.
