LM810M3-2.93/NOPB

Supervisors Overview

The LM810M3-2.93/NOPB is a 3-pin microprocessor reset circuit manufactured by Texas Instruments, housed in an SOT-23 package. It provides a fixed threshold voltage of 2.93 V for supply monitoring. The device features an active-high, push-pull reset output and includes an internal reset delay time of 840 ms to ensure stable power-up sequencing. It operates within a supply voltage range up to 5.5 V and supports a temperature range from -40°C to +105°C.

Supervisors Feature Summary

• Provides precise voltage supervision with a fixed 2.93 V threshold
• Delivers active-high reset signal via push-pull output stage
• Incorporates internal 840 ms reset delay for reliable power-on timing

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix '2.93' matches the required threshold voltage for your design, as this variant differs from other thresholds in the LM810 family. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the SOT-23 package dimensions align with your PCB footprint requirements.

Supervisors Selection Notes

Select this component when a fixed 2.93 V supervision level is required for low-voltage digital systems. The active-high output simplifies logic interfacing compared to open-drain alternatives. Consider the 840 ms delay duration to ensure compatibility with your target processor's minimum power-on reset pulse width requirements.

Supervisors Part Context

This part belongs to the LM809/LM810 series of 3-pin microprocessor reset circuits. While the LM809 typically offers active-low outputs, the LM810 variant specifically provides active-high signals. These devices are designed for compact applications requiring minimal component count for essential power management functions.

Supervisors Replacement Considerations

Publicly confirmed substitutes include LM810M3-2.93/NOPB.A. Verify pinout compatibility and electrical specifications before substituting with generic equivalents.
