LM809M3-4.63/NOPB TI Supervisory Circuit | SOT-23-3 | 4.63V Threshold, Active-Low Reset

Product Overview

The LM809M3-4.63/NOPB is a supervisory circuit from Texas Instruments designed to monitor power supply voltages in microprocessor systems. It provides a reset signal to the host processor when the supply voltage drops below a preset threshold, ensuring reliable system operation during power-up, power-down, and brownout conditions. Housed in a compact SOT-23-3 package, this device is ideal for space-constrained applications requiring precise voltage monitoring.
