LM3723EM5-2.32/NOPB

Supervisors Overview

The LM3723EM5-2.32/NOPB is a supervisory circuit manufactured by Texas Instruments, designed to monitor voltage levels and generate reset signals for microprocessors. It operates within a supply voltage range of 1.6 V to 5.5 V and features a fixed threshold voltage of 2.32 V. The device provides a push-pull/totem pole output that is active high. It includes a programmable reset pulse width with a minimum delay of 100 ms. The component is housed in an SC-74A (SOT-753) package and supports operation across a temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Monitors single power supply rail with fixed threshold
• Generates active-high reset signal via push-pull output
• Includes programmable reset pulse width timer

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix '2.32' confirms the 2.32V threshold voltage variant. Confirm the 'EM5' designation corresponds to the SC-74A/SOT-753 package. Ensure the 'NOPB' suffix indicates lead-free/RoHS compliance as per Texas Instruments standards. Cross-reference the manufacturer part number with official datasheets to confirm pinout and electrical characteristics match the design requirements.

Supervisors Selection Notes

Select this component when a fixed 2.32V threshold is required for low-voltage systems. The push-pull output eliminates the need for external pull-up resistors. Consider the 100ms minimum reset delay for applications requiring extended power-on stabilization. Verify that the operating voltage range of 1.6V to 5.5V aligns with the target supply rail.

Supervisors Part Context

This part belongs to the LM3723 family of supervisory circuits from Texas Instruments. These devices are engineered for reliable voltage monitoring in portable and industrial electronics. The family offers various threshold voltages and output configurations to suit different system architectures.

Supervisors Replacement Considerations

Check for LM3723 variants with different threshold voltages if 2.32V is not suitable. Verify pin-compatible alternatives from other manufacturers only if they explicitly support the same SC-74A package and electrical specifications.
