... ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the ADM8696/ADM8697 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...

... An output line on the processor is used to toggle the Watchdog Input (WDI) line. If this line is not toggled within the selected timeout period, a RESET pulse is generated. The ADM8696/ADM8697 may be configured for either a fixed “short” 100 “long” 1.6 second timeout period or for an should be BATT adjustable timeout period. If the “ ...
