Pinout
The MAX809RTRG is a microprocessor supervisory circuit designed to monitor power supplies in digital systems. It is typically available in a 3-pin SOT-23 package. The pin functions are as follows:
1. GND (Pin 1): This pin is connected to the ground reference of the circuit.
2. RESET (Pin 2): This active-low output pin asserts a reset signal when the monitored voltage drops below the specified threshold. It provides a reset pulse to the microprocessor to ensure it starts in a known state.
3. VCC (Pin 3): This pin is connected to the power supply voltage that is being monitored. The device checks this voltage and triggers a reset if it falls below a certain level.
The MAX809 series helps ensure reliable operation of microcontrollers or other digital systems by preventing erratic behavior due to undervoltage conditions.
