Analog Devices ADM8616/ADM8617 Product Handbook Rev B
The ADM8616 and ADM8617 are low‑voltage supervisory circuits with watchdog timers, designed to monitor power‑supply voltage and code‑execution integrity in microprocessor‑based systems. They provide a reset output (push‑pull for ADM8616, open‑drain for ADM8617) and offer multiple reset‑threshold, reset‑timeout, and watchdog‑timeout options.
The handbook includes functional block diagrams, pin descriptions, absolute‑maximum ratings, typical performance curves, and ordering information. It also outlines application areas such as microprocessor systems, controllers, intelligent instruments, and portable equipment.

Questions answered in these manuals
What supply voltage range does the ADM8616/ADM8617 support?
The devices operate with a supply voltage (Vee) from 1 V up to 5.5 V.
How many reset‑threshold options are available?
There are nine reset‑threshold options ranging from 1.52 V to 4.63 V.
What is the difference between the ADM8611 and the ADM8616/ADM8617/ADM8618?
The ADM8611 has a debounced manual reset input for an external push-button or logic signal. The ADM8616, ADM8617 and ADM8618 have an on-chip watchdog timer instead.
