Function

1 to 4

GND

Common Ground. Also provides heat-sink to PCB.

5, 9

SENSE

Output for current sense resistors.

6

INLB

Logic Input to turn on the lower driver (Active High).

7, 11

Supply Voltage.

24

INUB

Logic Input to turn on the upper drivers (Active Low).

25

OUTC

DMOS Half-bridge C Out.

26 to 28

GND

Common Ground. Also provides heat-sink to PCB.
