Pinout
The SGM809-SXN3L/TR is a microprocessor supervisory circuit with a 3-pin configuration. Its primary function is to monitor the supply voltage of microprocessor systems and ensure they operate within specified voltage thresholds. The device is designed to reset the microprocessor when the supply voltage falls below a preset threshold or during power-up, ensuring reliable operation.
Here is a brief overview of its pin functions:
1. GND (Ground): This pin is connected to the ground reference of the system.
2. VCC (Supply Voltage): It monitors the supply voltage to determine if it is within the specified range.
3. RESET (Output): This active-low pin is used to reset the microprocessor when the monitored voltage goes below the threshold value. The reset signal remains active until the voltage returns to a safe level and a specified reset timeout period has elapsed.
