... 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 ...

... BATTERY GND Figure 18a. ADM8696 Typical Application Circuit A Figure 18b shows a similar application for the ADM8696 but in this case the PFI input monitors the unregulated input to the 7805 voltage regulator. This gives an earlier warning of an im- pending power failure useful with processors operating at ...
