LM8364BALMFX45/NOPB

Supervisors Overview

The LM8364BALMFX45/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 backup battery switch function. The component is housed in a SOT-23-5 package and supports operation from -40°C to +85°C.

Supervisors Feature Summary

• Provides micropower undervoltage sensing for low-power applications
• Features an active-low open-drain output for system reset signaling
• Includes dedicated backup battery switch functionality
• Integrates power-fail detection capabilities

Supervisors Applications

• Battery-powered portable electronics monitoring
• Embedded systems requiring reliable power supervision
• Low-voltage circuit protection scenarios

Supervisors Procurement Notes

Verify the specific suffix 'X45' corresponds to the 4.5 V threshold variant when sourcing. 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 for single-input monitoring. It is suitable for designs needing low quiescent current and compact SOT-23-5 packaging. Consider alternative threshold variants if different voltage levels are needed. Verify that the active-low output polarity aligns with your downstream logic requirements.

Supervisors Part Context

This part belongs to the LM8364 series of Micropower Undervoltage Sensing Circuits from Texas Instruments. The series is designed for efficient power management in portable devices. The '/NOPB' designation indicates a lead-free, RoHS-compliant version of the original National Semiconductor product line, now managed by TI.

Supervisors Replacement Considerations

LM8364BALMF45/NOPB serves as a direct equivalent with identical electrical characteristics and pinout compatibility.
