This document describes the features and characteristics of the ADM705/ADM706/ADM707/ADM708 low-cost microprocessor supervisory circuits, including RESET validity, quiescent current, precision supply voltage monitoring, reset pulse width, debounced manual reset input, independent watchdog timer, power-fail or low battery warning, and more.
The ADM708 is a low‑cost microprocessor supervisory circuit that monitors 5 V power supplies and can detect power‑fail or low‑battery conditions. It offers a reset output, an active‑high reset option, and a watchdog timer to ensure reliable processor operation.
The handbook includes detailed specifications, pin configurations, typical performance graphs, and an ordering guide for the available PDIP, SOIC, and MSOP packages. It also covers absolute maximum ratings, ESD precautions, and functional block diagrams for system designers.
