LM8365BALMFX27/NOPB

Supervisors Overview

The LM8365BALMFX27/NOPB is a voltage supervisory circuit manufactured by Texas Instruments, designed for monitoring single-input power rails. It operates within a supply voltage range of 1 V to 6 V and features an active-low open-drain output. The device triggers at a threshold voltage of 2.7 V with a programmable reset delay time. It provides high accuracy of 2.5% and includes battery backup functionality. The component is housed in a compact SOT-23-5 package, suitable for surface-mount applications across an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides active-low open-drain output signaling for voltage supervision
• Features programmable reset delay timing for customized response control
• Includes battery backup switch capability to maintain monitoring during power transitions

Supervisors Applications

• Portable electronic devices requiring low quiescent current monitoring
• Battery-powered systems needing reliable voltage supervision
• Embedded circuits utilizing single-input power rail tracking

Supervisors Procurement Notes

Verify the complete part number including the suffix /NOPB to ensure lead-free compliance and specific threshold configuration. Confirm the SOT-23-5 package type matches your PCB footprint requirements. Check datasheet specifications for the exact 2.7 V threshold tolerance and programmable delay settings before integration into final designs.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with low power consumption is required. The 2.7 V threshold suits applications where the monitored rail operates above this level. Consider the programmable delay feature if noise immunity or specific startup sequencing is necessary. Ensure the 6 V maximum input rating aligns with the system's highest possible supply voltage.

Supervisors Part Context

This part belongs to the LM8365 family of MicroPwr under-voltage sensing circuits from Texas Instruments. It shares the SOT-23-5 package and general architecture with other variants like the LM8365BALMFX45/NOPB, differing primarily in the fixed threshold voltage setting. The family is designed for space-constrained, battery-operated applications.

Supervisors Replacement Considerations

Direct substitutes include other LM8365 variants with different thresholds, such as LM8365BALMFX45/NOPB (4.5 V) or LM8364BALMFX20/NOPB (2.0 V), provided the threshold matches the application requirement. Verify that the replacement maintains the same active-low open-drain output and SOT-23-5 package compatibility.
