Analog Devices ADM8696/ADM8697 Datasheet
The ADM8696 and ADM8697 are single‑chip supervisory circuits that provide power‑on reset, watchdog timer, battery backup switching, and power‑fail detection for microprocessor systems. They support adjustable reset thresholds, multiple watchdog timeout options, and can drive up to 100 mA on the Vout pin.
The devices are offered in 16‑pin DIP, SOIC (wide‑body) and TSSOP packages and include pin‑out diagrams, absolute maximum ratings, and typical performance curves. Detailed specifications cover operating voltage ranges, low‑line thresholds, standby currents, and timing parameters for reset and watchdog functions.
