Note 1: V PIN refers to the voltage of the driver output. V SOURCE refers to the power source for the driver. ADPPWR, REVBLK, ADP-
BLK, DISBAT, DISA, DISB, CHGA, and CHGB gate drivers correspond to sources at ADPIN, EXTLD, EXTLD, CHGIN, BATA,
BATB, CHGIN, and CHGIN, respectively.
Note 2: Guaranteed by design. Not production tested.
