LM809M3-2.63/NOPB

Supervisors Overview

The LM809M3-2.63/NOPB is a voltage supervisory integrated circuit manufactured by Texas Instruments, designed to monitor a single power supply rail. It features an active-low, push-pull output and operates within a supply voltage range up to 5.5 V. The device provides a fixed reset delay time of 240 ms and maintains an accuracy of 5%. It is housed in a SOT-23-3 surface-mount package and supports an operating temperature range from -40°C to +105°C.

Supervisors Feature Summary

Provides reliable system reset generation through active-low, push-pull output configuration
Monitors a single input voltage channel with specified threshold accuracy
Operates across extended industrial temperature ranges for robust performance

Supervisors Applications

Microprocessor system hardware monitoring
Portable equipment power management
Battery-powered system supervision

Supervisors Procurement Notes

Verify the specific suffix '2.63' to confirm the 2.63 V threshold voltage requirement matches the target application design. Ensure the SOT-23-3 package footprint aligns with the PCB layout constraints. Confirm RoHS compliance status if required by environmental regulations. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability.

Supervisors Selection Notes

Select this component when a fixed 2.63 V threshold is required for single-channel voltage supervision. Consider the 240 ms reset delay and 5% accuracy specifications against system timing requirements. Evaluate the SOT-23-3 package size for space-constrained designs. Compare against other LM809 variants if different threshold voltages or packaging options are needed.

Supervisors Part Context

This part belongs to the LM809 series of supervisory circuits from Texas Instruments. The series offers various threshold voltages and packaging options to suit different monitoring needs. The LM809 family is commonly used in applications requiring simple reset generation without manual reset or watchdog timer functionality.
