LM3724IM5-2.32/NOPB

Supervisors Overview

The LM3724IM5-2.32/NOPB is a processor supervisor circuit manufactured by Texas Instruments, designed to monitor voltage levels and generate reset signals for microprocessors. It features a single monitored input with a fixed threshold of 2.32V. The device provides an active low/open drain output and includes a minimum reset timeout of 100ms. It operates within a temperature range of -40°C to +125°C and is housed in a 5-pin SOT-23 surface-mount package.

Supervisors Feature Summary

• Provides simple reset or power-on-reset functionality for digital systems
• Features an active low open-drain output compatible with various logic families
• Includes a guaranteed minimum reset timeout duration to ensure stable system initialization

Supervisors Applications

• Microprocessor power supply monitoring
• Embedded system reset generation
• Battery-powered device supervision

Supervisors Procurement Notes

Verify the specific suffix 'IM5' corresponds to the SOT-23-5 package variant and '-2.32' indicates the 2.32V threshold. Confirm 'NOPB' denotes lead-free/RoHS compliance. Check current lifecycle status as TI may update product recommendations. Ensure the ordering part number matches the exact voltage threshold required for your application design.

Supervisors Selection Notes

Select this component when a fixed 2.32V threshold is required for voltage supervision. The SOT-23-5 package suits space-constrained designs. Verify that the active low open-drain output aligns with the target microprocessor's reset input requirements. Consider the operating temperature range if the application involves extreme environmental conditions.

Supervisors Part Context

This part belongs to the LM3724 family of voltage supervisors from Texas Instruments. These devices are engineered for reliable power management in portable and industrial electronics. The family offers various threshold voltages and package options to accommodate different system architectures and footprint constraints while maintaining consistent performance characteristics.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the LM372x series with matching 2.32V thresholds. Verify electrical parameters such as reset timeout and quiescent current against original specifications before substitution.
