The MAX809MEXR+T has a standard SOT-23-3 package with the following pin configuration:
```
| | --| RESET | --| GND | --| VCC | |___________| ```
The MAX809MEXR+T operates by comparing the supply voltage with a fixed threshold voltage. When the supply voltage drops below the threshold, the internal circuitry generates a reset signal. The reset signal remains active for a specified timeout period after the supply voltage rises above the threshold again. This ensures that the microprocessor or system is properly reset and initialized.
Note: This entry provides a brief overview of the MAX809MEXR+T. For complete information, refer to the product datasheet and specifications provided by the manufacturer.
