Overview
The ADM707ARZ-REEL is a microprocessor supervisory circuit produced by Analog Devices Inc. This component is designed to provide power-supply monitoring circuitry, generating a reset output during power-up, power-down, and brownout conditions. It features a 1.25V threshold detector for power-fail warnings and low battery detection, making it suitable for monitoring additional power supplies. The device includes an active low and debounced manual reset input (MR) and offers both active high and active low reset outputs. It is widely used in microprocessor systems, computers, controllers, intelligent instruments, and other critical microprocessor supply monitoring applications.
