LM8364BALMF27/NOPB

Supervisors Overview

The LM8364BALMF27/NOPB is a micropower undervoltage sensing circuit manufactured by Texas Instruments. It operates within a supply voltage range of 1 V to 6 V and features an active-low, open-drain output. The device monitors a single input with a threshold voltage of 2.7 V, providing an accuracy of 2.5%. It includes power-fail detection and a backup battery switch function but lacks manual reset or watchdog timer capabilities. The component is housed in a SOT-23-5 package and supports surface-mount installation.

Supervisors Feature Summary

• Provides micropower undervoltage monitoring with high accuracy
• Features active-low open-drain output for system reset signaling
• Includes backup battery switch functionality for power continuity

Supervisors Applications

• Portable electronic devices requiring low quiescent current
• Battery-powered systems needing power-fail detection
• Embedded circuits requiring reliable voltage supervision

Supervisors Procurement Notes

Verify the specific suffix 'F27' corresponds to the 2.7 V threshold variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Ensure the SOT-23-5 package footprint matches your PCB design constraints. Cross-reference the datasheet revision date to ensure compatibility with latest electrical specifications.

Supervisors Selection Notes

Select this component when a fixed 2.7 V undervoltage threshold is required for single-input monitoring. It is suitable for applications prioritizing low power consumption over programmable delay features found in the LM8365 series. Consider the 2.5% accuracy specification for precision requirements. Evaluate the absence of manual reset if user intervention is necessary for recovery.

Supervisors Part Context

This part belongs to the LM8364 family of micropower undervoltage sensing circuits from Texas Instruments. It is distinct from the LM8365 series, which offers programmable output delays. The LM8364 provides a simpler solution for basic voltage supervision tasks without additional timing configuration needs.

Supervisors Replacement Considerations

LM8364BALMF20/NOPB serves as a substitute with a 2.0 V threshold. LM8364BALMF45/NOPB is available for a 4.5 V threshold requirement. These variants share identical pinouts and functional characteristics except for the trip point voltage.
