... Out” conditions. The RESET output is guaranteed to be functional (logic low) with V The ADM699 features an identical monitoring circuit as in the ADM698 plus an additional watchdog timer input to monitor microprocessor activity. The RESET output is forced low if the watchdog input is not toggled within the 1 second watchdog timeout period ...

... 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 ADM698/ADM699 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 ...

... ADM698/ADM699 CIRCUIT INFORMATION Power Fail RESET A precision voltage detector monitors V RESET output to hold the microprocessor’s Reset line low when V falls below the reset threshold (4.65 V) (see Figure 4). The CC reset voltage threshold is set to accommodate a 5% variation The voltage detector has 40 mV hysteresis to ensure that ...
