Pinout
The MAX809MEUR+T is a microprocessor supervisory circuit. It is designed to monitor the supply voltage of digital systems and provide a reset signal to the microprocessor during power-up, power-down, and brownout conditions.
This device typically comes in a SOT-23 package, which has 3 pins:
1. VCC (Pin 1): This is the input pin for the supply voltage that the MAX809 monitors.
2. GND (Pin 2): Ground pin, which is the reference point for the supply voltage.
3. RESET (Pin 3): This is the output pin that provides the reset signal to the microprocessor. When the monitored voltage falls below a predefined threshold, the RESET output is asserted.
The MAX809MEUR+T ensures reliable system operation by generating a reset whenever the monitored voltage is out of the specified range, thus preventing improper operation of the microprocessor.
