LM809M3X-2.45/NOPB

Supervisors Overview

The LM809M3X-2.45/NOPB is a voltage supervisor from Texas Instruments featuring a fixed 2.45V threshold. It monitors supply voltages and generates a reset signal when the input drops below the specified level. The device operates within a wide supply voltage range and includes an open-drain output for flexible interfacing with various logic families.

Supervisors Feature Summary

• Fixed voltage monitoring threshold at 2.45V
• Open-drain reset output configuration
• Compact SOT-23-3 package design

Supervisors Applications

• Portable battery-powered equipment
• Microprocessor system supervision
• Consumer electronics power management

Supervisors Procurement Notes

Verify the complete part number including the NOPB suffix to ensure lead-free compliance and RoHS adherence. Confirm the specific temperature grade and packaging variant matches the project requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a precise 2.45V supervision threshold is required for low-voltage systems. Consider the open-drain output capability for compatibility with different logic levels. Ensure the operating voltage range covers the minimum and maximum supply conditions of the target application.

Supervisors Part Context

This part belongs to the LM809 family of voltage supervisors designed for reliable system reset generation. It provides essential protection against brown-out conditions in embedded systems. The series offers various threshold options to suit different voltage rails.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives with identical 2.45V thresholds. Verify that any substitute maintains the same open-drain output structure and package dimensions to ensure seamless integration without PCB redesign.
