The LM809M3-4.63 is a microprocessor supervisory circuit designed to monitor power supplies in microprocessor systems. It has a 3-pin configuration. The pins are typically designated as follows:
1. VCC (Power Supply Input): This pin is connected to the power supply that needs monitoring. It is responsible for detecting when the voltage drops below a pre-defined threshold (4.63V in the case of LM809M3-4.63).
2. GND (Ground): This is the ground reference pin for the device. It should be connected to the system ground.
3. RESET (Active-Low Reset Output): This pin provides the reset signal to the microprocessor. The output remains low when the monitored voltage is below the threshold and for a specified time after the voltage rises above the threshold, ensuring the microprocessor is properly reset.
The primary function of the LM809M3-4.63 is to provide a reliable reset signal to microprocessors during power-up, power-down, and brownout conditions, ensuring stable operation by preventing code execution errors.
