ADM696/ADM697 are high performance microprocessor supervisory circuits, with power failure, battery discharge, low voltage monitoring, clock signal switching and automatic reset functions.
The ADM696 and ADM697 are microprocessor supervisory circuits that provide power‑monitoring, reset, watchdog timer, battery‑backup switching and RAM write‑protect functions. They are offered in 16‑pin DIP and Q‑package options for use in microprocessor systems, controllers and automotive applications.
The document includes functional block diagrams, detailed electrical specifications, ordering information, pin configurations, timing diagrams and typical performance curves to help designers integrate the devices into their designs.
| VCC Operating Voltage Range | 3.0 V – 5.5 V |
|---|---|
| VBATT Operating Voltage Range | 2.0 V – VCC‑0.3 V |
| Supply Current (Excludes I_OUT) | 1.95 mA |
| VOUT Output Voltage (Battery Backup) | VCC – 0.05 V |
| RESET Output Voltage @ VCC = +1 V | 200 mV |
The watchdog timeout can be set to a short 100 ms period, a long 1.6 s period, or an adjustable value using an external clock or capacitor.
