Analog Devices ADM809
The ADM803/ADM809/ADM810 supervisory circuits monitor the power supply voltage in microprocessor systems. They provide a reset output during power-up, power-down, and brownout conditions. This holds the microprocessor in a reset state until conditions have stabilized.- Min Voltage : 1V
- Max Voltage : 5.5V
- Max Operating Temp : 125°C
- Min Operating Temp : -40°C
