LM8364BALMF45/NOPB

Supervisors Overview

The LM8364BALMF45/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 4.5 V, exhibiting an accuracy of 2.5%. It includes power-fail detection and a battery backup switch but lacks manual reset or watchdog timer functions. The component is housed in a SOT-23-5 package and supports operation from -40°C to +85°C.

Supervisors Feature Summary

• Micropower undervoltage sensing capability for low-power applications
• Active-low open-drain output configuration
• Integrated battery backup switch functionality

Supervisors Applications

• Portable electronic devices requiring efficient power monitoring
• Battery-operated systems needing undervoltage protection
• General-purpose voltage supervision in consumer electronics

Supervisors Procurement Notes

Verify the specific suffix '45' 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 requirements. Cross-reference the full part number including '/NOPB' to guarantee lead-free manufacturing standards are met for your assembly process.

Supervisors Selection Notes

Select this component when a fixed 4.5 V undervoltage threshold is required without programmable delay features. It is suitable for designs prioritizing low quiescent current over complex timing control. Consider alternative models if manual reset inputs or watchdog timers are necessary for system reliability. Verify that the 2.5% accuracy meets your application's tolerance specifications.
