NOTES

1. THE EXPOSED PAD OF THE PACKAGE IS NOT DIRECTLY

CONNECTED TO ANY PIN OF THE PACKAGE, BUT IT IS

ELECTRICALLY AND THERMALLY CONNECTED TO THE DIE

SUBSTRATE, WHICH IS THE GROUND OF THE DEVICE.

Description

1

SD

Output Shutdown. When high, this pin disables normal operation, forcing OUTA and OUTB low.

2

INA

Inverting Input Pin for Channel A Gate Driver.

3

PGND

Ground. This pin should be closely connected to the source of the power MOSFET.

4

INB

Inverting Input Pin for Channel B Gate Driver.

5

OUTB

Output Pin for Channel B Gate Driver.

6

VDD

Power Supply Voltage. Bypass this pin to PGND with a ~1 µF to 5 µF ceramic capacitor.

7

OUTA

Output Pin for Channel A Gate Driver.

8

OTW

Overtemperature Warning Flag. Open drain, active low.
