LM8365BCLMFX30/NOPB

Supervisors Overview

The LM8365BCLMFX30/NOPB is a voltage supervisory circuit manufactured by Texas Instruments, designed to monitor a single input channel. It features an active-low open-drain output and operates within a supply voltage range of 1 V to 6 V. The device provides a precise threshold voltage of 3.0 V with an accuracy of ±2.5%. It includes power-fail detection capabilities and supports battery backup switching. The reset delay time is programmable, allowing for customized timing configurations. The component is housed in a compact SOT-23-5 package and functions reliably across an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Extremely low quiescent current consumption for energy-efficient operation
• High accuracy threshold voltage monitoring with ±2.5% precision
• Programmable reset delay time for flexible system timing control
• Integrated power-fail detection and battery backup switch functionality

Supervisors Applications

• Portable electronic devices requiring low standby power
• Battery-powered systems needing reliable voltage supervision
• Embedded controllers requiring power-fail signaling
• Industrial equipment operating in extended temperature ranges

Supervisors Procurement Notes

Verify the specific suffix 'CLMF' indicates the 3.0 V threshold variant when ordering. Confirm the 'X27' or similar tape-and-reel packaging designation matches production requirements. Ensure compatibility with SOT-23-5 footprint designs. Check RoHS compliance documentation for regulatory adherence. Validate that the active-low open-drain output aligns with downstream logic interface specifications.

Supervisors Selection Notes

Select this component when a single-channel supervisor with high accuracy is required. The 3.0 V threshold suits applications monitoring 3.3 V or similar nominal rails. Consider the low quiescent current for battery life optimization. The programmable delay allows synchronization with system startup sequences. Ensure the open-drain output can be properly pulled up to the desired logic level.

Supervisors Part Context

This part belongs to the LM8365 series of voltage supervisors from Texas Instruments. The series offers various threshold voltages to accommodate different rail monitoring needs. The LM8365 family is characterized by ultra-low power consumption and high precision. It serves as a critical component for ensuring system stability during power transitions.

Supervisors Replacement Considerations

The LM8365BALMFX30/NOPB is a direct functional substitute with identical electrical characteristics. Verify pinout compatibility before substitution. Ensure the replacement maintains the same SOT-23-5 package dimensions.
