Pinout
The ADM809SARTZ-REEL7 is a microprocessor supervisory circuit. It typically comes in a SOT-23-3 package, which means it has 3 pins. These devices are designed to monitor the supply voltage of microprocessors and digital systems, ensuring proper operation and reset functions when necessary.
Here is a brief overview of the functions associated with its pins:
1. VCC (Pin 3): This pin is connected to the power supply voltage that is being monitored.
2. GND (Pin 2): This is the ground pin and serves as a reference for the IC.
3. RESET (Pin 1): This output pin is used to reset the microprocessor when the monitored voltage drops below a specified threshold. The ADM809 asserts a reset signal whenever VCC falls below the threshold, and it remains asserted for a fixed time after VCC has risen above the threshold again.
These supervisory circuits are essential for ensuring reliable operation by preventing erroneous conditions when the power supply is inadequate.
