ADP3121 Overview
Pin Name 1 BST 2 IN 3 OD 4 VCC 5 DRVL 6 PGND 7 SW 8 DRVH Description Upper MOSFET Floating Bootstrap Supply. A capacitor connected between the BST and SW pins holds this bootstrapped voltage for the high−side MOSFET while it is switching. This pin has primary control of the drive outputs.
