The slide here shows how the NCP51561 can be configured as either a dual-input or single-input gate driver. On the left side of the screen, if pin 7 (the ANB input) is tied to ground, then OUTA equals INA and OUTB equals INB. On the right side of the screen, if pin 7 (the ANB input) is tied to V_DD, then OUTA equals INA and OUTB equals the compliment of OUTA.
