Overview
The ADM810MART-REEL7 is a microprocessor supervisory circuit produced by Analog Devices Inc. This component is designed to monitor the power supply voltage in microprocessor systems, ensuring reliable operation during power-up, power-down, and brownout conditions. The ADM810MART-REEL7 provides a reset output to hold the microprocessor in a reset state until the power supply has stabilized.
The device features a push-pull RESET output, which remains operational even when the VCC voltage drops as low as 1 V. It includes an internal timer that asserts the reset for a minimum of 240 ms during power-up, ensuring that the microprocessor starts in a stable state.
