PIN FUNCTIONS

SOIC-8

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.

NC

No connection.

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.
