... With a 3.3-V power rail voltage the minimum high input voltage is 1.5 V, making it compatible with 1.8-V logic. The Si4788CY is designed to give a steady dv/dt on the output during turn-on even with capacitive loads. The output rise time is 280-ms typical with a 100-mF load, which corresponds to a dv/dt of about 20 V/ms capacitive inrush current of around 2-A max with a 100-mF load ...
