LM8365BALMFX45/NOPB

Supervisors Overview

The LM8365BALMFX45/NOPB is a MicroPwr under-voltage sensing circuit manufactured by Texas Instruments. It operates within a supply voltage range of 1 V to 6 V and features a fixed under-voltage threshold of 4.5 V with an over-voltage threshold of 4.613 V. The device provides active low, open-drain output and includes programmable reset delay time. It offers 2.5% accuracy and supports battery backup switching. The component is housed in a SOT-23-5 package and functions without manual reset or watchdog timer capabilities.

Supervisors Feature Summary

• Provides under-voltage and over-voltage monitoring for single-input systems
• Features programmable reset delay time for customized timing control
• Supports battery backup switching to maintain system integrity during power transitions

Supervisors Applications

• Portable electronic devices requiring low quiescent current monitoring
• Battery-powered systems needing under-voltage detection
• General purpose voltage supervision in embedded circuits

Supervisors Procurement Notes

Verify the specific suffix 'F45' corresponds to the 4.5 V threshold variant when ordering. Confirm RoHS compliance status through official manufacturer documentation. Ensure the SOT-23-5 package footprint matches your PCB design constraints. Check for any specific handling requirements related to electrostatic discharge sensitivity during assembly.

Supervisors Selection Notes

Select this component when a fixed 4.5 V under-voltage threshold is required. Consider the 2.5% accuracy specification for precision applications. Evaluate the programmable reset delay feature against system startup requirements. Compare the 1 V to 6 V operating range with your system's supply voltage stability.

Supervisors Part Context

This part belongs to the LM8365 series of MicroPwr supervisory circuits from Texas Instruments. The series focuses on low-power voltage monitoring solutions. Other variants in the family offer different threshold voltages, such as 2.7 V options. The NOPB suffix indicates lead-free and RoHS-compliant manufacturing.

Supervisors Replacement Considerations

LM8365BALMFX27/NOPB offers similar functionality with a 2.7 V threshold instead of 4.5 V.
