Analog Devices ADM690/ADM695 Supervisory Circuits Datasheet
The ADM690‑ADM695 family provides power‑supply monitoring, battery backup switching, watchdog timer and RAM write‑protection for microprocessor systems. The devices are offered in 8‑pin DIP (ADM690, ADM692, ADM694) and 16‑pin DIP/SO (ADM691, ADM693, ADM695) packages.
Key functions include a reset output that stays active down to 1 V, a high‑current (up to 100 mA) Vout driver, adjustable watchdog timeout periods, and fast chip‑enable gating (5 ns). The document lists electrical specifications, pin configurations, functional block diagrams and application notes for automotive, industrial and consumer electronics.
