LM3724EM5-4.63/NOPB

Supervisors Overview

The LM3724EM5-4.63/NOPB is a supervisory circuit manufactured by Texas Instruments, designed to monitor a single voltage input. It operates within an extended temperature range of -40°C to +125°C and utilizes a 5-pin SOT-23 surface-mount package. The device features a fixed threshold voltage of 4.63V for power supply supervision. It provides a low-active open-drain reset output with a minimum reset timeout of 100ms. This component belongs to the LM3724 series and supports manual reset functionality.

Supervisors Feature Summary

• Monitors a single voltage input for power supply supervision
• Provides a low-active open-drain reset signal
• Supports manual reset functionality via dedicated pin
• Operates across an extended industrial temperature range

Supervisors Applications

• Microprocessor reset circuits
• Power supply monitoring systems
• Embedded system supervision

Supervisors Procurement Notes

Verify the exact part number including suffixes such as /NOPB against official manufacturer datasheets to ensure correct threshold voltage and package type. Confirm that the specific variant matches the required 4.63V threshold and SOT-23-5 packaging. Check current production status and lifecycle stage before procurement planning.

Supervisors Selection Notes

Select this component when a fixed 4.63V threshold is required for supervising a specific rail. Ensure the application demands a low-active open-drain output compatible with the target logic levels. Verify that the manual reset feature aligns with system requirements. Confirm compatibility with the available SOT-23-5 footprint during PCB layout design.

Supervisors Part Context

This device is part of the LM372x family of supervisory circuits from Texas Instruments. These components are engineered for reliable power management in electronic systems. The LM3724 specifically offers manual reset capability alongside standard power-on reset functions. It is categorized under PMIC supervisory circuits for robust system protection.

Supervisors Replacement Considerations

LM3724EM5-3.08/NOPB shares the same package and functional interface but differs in threshold voltage. LM3722IM5-4.63/NOPB offers a push-pull output instead of open-drain. Verify electrical compatibility and pinout alignment before substitution.
