LM810M3X-2.63

Supervisors Overview

The LM810M3X-2.63/NOPB is a voltage supervisory circuit manufactured by Texas Instruments, designed for monitoring single power supply rails. It operates within a maximum supply voltage of 5.5 V and features an active-low, push-pull reset output. The device triggers at a threshold voltage of 2.63 V with a fixed reset delay time of 240 ms. It supports surface-mount installation in a SOT-23-3 package and functions reliably across an extended temperature range from -40 °C to +105 °C.

Supervisors Feature Summary

• Provides hardware-based supervision for critical power rails using a dedicated voltage threshold.
• Generates a system reset signal via an active-low, push-pull output interface.
• Ensures stable operation through a defined reset delay period following voltage recovery.

Supervisors Applications

• Microprocessor system power-on reset generation
• Battery-powered equipment voltage monitoring
• Portable electronic device power management

Supervisors Procurement Notes

Verify the specific suffix designation against official documentation to confirm pinout compatibility and electrical characteristics. Ensure the selected variant matches the required operating temperature range and output polarity for the target application design.

Supervisors Selection Notes

Select this component when a low-pin-count solution is required for basic voltage monitoring tasks. Consider the fixed threshold value and reset delay timing to ensure alignment with the target system's startup requirements and noise immunity specifications.

Supervisors Part Context

This part belongs to the LM810 series of voltage supervisors, which are optimized for compact designs requiring minimal external components. The family typically offers various threshold options to accommodate different standard voltage rails commonly found in consumer and industrial electronics.

Supervisors Replacement Considerations

Consult manufacturer datasheets for direct equivalents with matching threshold voltages and package types. Verify that any substitute maintains the same output configuration and thermal performance ratings.
