ADM8616/ADM8617 are low voltage supervisory circuits that monitor power supply voltages from 1.8 V to 5 V.
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.
| Supply Voltage Range | 1 V – 5.5 V |
|---|---|
| Supply Current (Vee = 5.5 V) | 10 µA – 20 µA |
| Reset Timeout Options | 1 ms, 20 ms, 140 ms, 1120 ms |
| Operating Temperature Range | ‑40 °C to +85 °C |
| Absolute Maximum Vee Rating | ‑0.3 V to +6 V |
| Open‑Drain Reset Output Voltage | 0.3 V |
| Reset Output Leakage Current | 1 pA |
The devices operate with a supply voltage (Vee) from 1 V up to 5.5 V.
There are nine reset‑threshold options ranging from 1.52 V to 4.63 V.
