Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.

Push-Pull Output Stage for ADM8616.
Open-Drain Output Stage for ADM8617.
3 WDI
Watchdog Input. Generates a
RESET if the logic level on the pin remains low or high for the duration of the
watchdog timeout. The timer is cleared if a logic transition occurs on this pin, or if a reset is generated. Leave
floating to disable the watchdog timer.
