Analog Devices ADM6821-ADM6825 Datasheet
The ADM682x family provides low‑voltage supervisory circuits with watchdog and manual reset functions, designed for microprocessor‑based systems, computers, controllers, intelligent instruments, and portable equipment. Each device monitors supply voltage and can generate power‑on reset signals, with optional watchdog timing to reset a processor if it stops responding.
Key features include nine selectable reset thresholds (1.58 V to 4.63 V), a 140 ms minimum reset timeout, a 1.6 s watchdog timeout, push‑pull or open‑drain reset outputs, manual reset input, and ultra‑low 7 pA supply current. The parts are offered in a 5‑lead SOT‑23 package and operate from –40 °C to +125 °C.
