LM3723EM5-4.63/NOPB

Supervisors Overview

The LM3723EM5-4.63/NOPB is a supervisory circuit manufactured by Texas Instruments, designed for monitoring power supply voltages in electronic systems. It operates within an extended temperature range of -40°C to +125°C and utilizes a compact SOT-23-5 surface-mount package. The device features a fixed voltage threshold of 4.63V, ensuring precise detection of under-voltage conditions. It provides a manual reset capability alongside standard power-on reset functionality, offering flexibility in system control. The output stage is configured as push-pull/totem pole with high active polarity, delivering robust drive capabilities for downstream logic components.

Supervisors Feature Summary

• Integrated manual reset button interface for user-initiated system recovery
• Push-pull output stage providing strong drive capability without external pull-up resistors
• High-active reset signal polarity for direct interfacing with microprocessor reset pins

Supervisors Applications

• Microprocessor power supply supervision
• Battery-powered equipment voltage monitoring
• Industrial control system reset circuits

Supervisors Procurement Notes

Verify the exact suffix configuration against the manufacturer's current datasheet to ensure compatibility with specific design requirements. Confirm that the 4.63V threshold aligns with the target system's voltage rails. Check for any recent lifecycle notices or obsolescence warnings from Texas Instruments before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 4.63V threshold is required for power monitoring applications. The push-pull output eliminates the need for external pull-up components, simplifying board layout. Ensure the operating temperature range meets the environmental conditions of the intended application.
