PIN FUNCTIONS
Pin # Name Description
1 VDD
Supply input. This pin supplies power to all the internal circuitry. Place a decoupling
capacitor to ground close to this pin to ensure stable and clean supply.
2 BST
Bootstrap. This is the positive power supply for the internal floating high-side MOSFET
driver. Connect a bypass capacitor between this pin and SW pin.
3 DRVH Floating driver output.
4 SW Switching node.
5 INH Control signal input for the floating driver.
6 INL Control signal input for the low side driver.
7
VSS,
exposed pad
Chip ground. Connect exposed pad to VSS for proper thermal operation.
8 DRVL Low side driver output.
