LM8365BALMF22/NOPB

Supervisors Overview

The LM8365BALMF22/NOPB is a micropower undervoltage-sensing circuit from Texas Instruments, designed for battery-powered microprocessor systems. It features an active-low open-drain output and monitors a single input with a threshold voltage of 2.2 V. The device operates within a supply voltage range of 1 V to 6 V and maintains accuracy within 2.5%. It supports programmable reset delay times and includes power-fail detection capabilities. The component is housed in a compact SOT-23-5 package and functions reliably across temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Micropower operation ideal for extending battery life in portable devices
• Active-low open-drain output for direct interface with logic circuits
• Programmable reset delay time to accommodate specific system startup requirements
• Integrated power-fail detection for monitoring supply integrity

Supervisors Applications

• Battery-powered microprocessor-based systems
• Portable electronic devices requiring low quiescent current
• Embedded systems needing reliable undervoltage supervision

Supervisors Procurement Notes

Verify the exact threshold voltage suffix (22 indicates 2.2 V) against schematic requirements. Confirm the SOT-23-5 package footprint matches the PCB design. Ensure the active-low output polarity aligns with the connected microcontroller or logic gate inputs. Check temperature ratings for environmental compatibility.

Supervisors Selection Notes

Select this component when a low-cost, low-power supervisor is needed for single-channel monitoring. The 2.2 V threshold suits lithium-ion or alkaline battery applications where voltage drops below nominal levels. Consider the open-drain output requirement for pull-up resistor implementation. Evaluate the programmable delay feature if slow power-up sequences are present.

Supervisors Part Context

This part belongs to the LM8365 series of micropower undervoltage sensing circuits. It shares functional similarities with other members like the LM8364 but differs in threshold voltages and pin configurations. The series is optimized for cost-sensitive consumer electronics and industrial control applications where power efficiency is critical.

Supervisors Replacement Considerations

Direct substitutes include LM8365 variants with different threshold suffixes (e.g., LM8365BALMFX27/NOPB for 2.7 V). Cross-reference with LM8364 series for similar functionality but verify pinout compatibility. Ensure replacement parts maintain the same SOT-23-5 package and electrical characteristics.
