Analog Devices ADM803/ADM809/ADM810 Microprocessor Supervisory Circuits Datasheet
The document describes the ADM803/ADM809/ADM810 family of microprocessor supervisory circuits designed to monitor power supply voltage in microprocessor systems. These devices provide a reset output during power-up, power-down, and brownout conditions to ensure system stability.
Available with seven different reset threshold voltage options (2.5 V to 5 V), the circuits feature built-in glitch immunity and low power consumption of only 17 pA. The ADM803 utilizes an open-drain output, while the ADM809 and ADM810 provide push-pull outputs.
