LM810M3X-4.63/NOPB

Supervisors Overview

The LM810M3X-4.63/NOPB is a voltage supervisory circuit manufactured by Texas Instruments, designed for supply monitoring applications. It operates within a maximum supply voltage of 5.5 V and features an active-high, push-pull reset output. The device monitors a single input with a threshold voltage of 4.63 V and includes an overvoltage detection capability at 4.7 V. It provides a reset delay time of 840 ms and lacks manual reset or watchdog timer functions. The component supports surface-mount installation in a SOT-23-3 package and functions reliably across a temperature range from -40°C to +105°C.

Supervisors Feature Summary

• Provides active-high, push-pull reset signaling for reliable logic interface compatibility.
• Includes dedicated overvoltage detection functionality to monitor supply integrity beyond standard thresholds.
• Operates without requiring manual reset inputs or external watchdog timers for basic supervision.

Supervisors Applications

• Microprocessor system power supply monitoring
• Battery-powered equipment voltage supervision
• Portable electronics power management

Supervisors Procurement Notes

Verify the specific suffix 'X' against official datasheets to confirm tape-and-reel packaging specifications. Ensure the part number matches the exact threshold voltage requirements for your design. Confirm RoHS compliance status through manufacturer documentation before procurement.

Supervisors Selection Notes

Select this component when an active-high output is required for reset signaling. Consider the 840 ms reset delay duration to ensure compatibility with target microcontroller startup sequences. Evaluate the SOT-23-3 package constraints against available PCB space and thermal requirements.

Supervisors Part Context

This device belongs to the LM810 series of voltage supervisors from Texas Instruments. It shares functional similarities with other parts in the family but is distinguished by its specific 4.63 V threshold and active-high output configuration. The series is designed for compact, low-power monitoring tasks in portable and industrial electronics.

Supervisors Replacement Considerations

The LM810M3-4.63/NOPB is listed as an alternate part. Verify pinout compatibility and electrical parameter equivalence before substitution. Check for any differences in manufacturing revisions or packaging formats between the original and alternate numbers.
