Description

26

DGND

Digital Ground.

27

OUT-NB2

Output N-Channel gate driver for channel B

28

DV

Gate drive supply voltage. Supplies digital circuitry portion of the gate driver and the main

output stage for OUT-PA2, OUT-NA2, OUT-NA3, OUT-PB2, OUT-NB2, and OUT-NB3.

Should be at the same potential as AV

29

OUT-NB3

Output N-Channel gate driver for channel B

30

DGND

Digital Ground.

31

DV

Gate drive supply voltage. Supplies digital circuitry portion of the gate driver and the main

output stage for OUT-PA2, OUT-NA2, OUT-NA3, OUT-PB2, OUT-NB2, and OUT-NB3.

Should be at the same potential as AV

32

OUT-NA3

Output N-Channel gate drivers for channel A.

33

DV

Gate drive supply voltage. Supplies digital circuitry portion of the gate driver and the main

output stage for OUT-PA2, OUT-NA2, OUT-NA3, OUT-PB2, OUT-NB2, and OUT-NB3.

Should be at the same potential as AV

34

OUT-NA2

Output N-Channel gate drivers for channel A.

35

DGND

Digital Ground.

36

DV

Gate drive supply voltage. Supplies digital circuitry portion of the gate driver and the main

output stage for OUT-PA1, OUT-NA1, OUT-PB1, and OUT-NB1. Can be at a different po-

tential than DV

37

OUT-NA1

Output N-Channel gate drivers for channel A.

38

N/C

No connect.

39

OUT-PA1

Output P-Channel gate drivers for channel A

40

DV

Gate drive supply voltage. Supplies digital circuitry portion of the gate driver and the main

output stage for OUT-PA1, OUT-NA1, OUT-PB1, and OUT-NB1. Can be at a different po-

tential than DV

41

OUT-PA2

Output P-Channel gate drivers for channel A

42

DV

Gate drive supply voltage. Supplies digital circuitry portion of the gate driver and the main

output stage for OUT-PA2, OUT-NA2, OUT-NA3, OUT-PB2, OUT-NB2, and OUT-NB3.

Should be at the same potential as AV

43

DGND

Digital Ground.

44

OUT-PA3

Output P-Channel gate drivers for channel A

45

DVSS

Gate drive supply voltage for OUT-PA3 and OUT-PB3. Supplies digital circuitry portion and

the main output stage. Should be at the same potential as AVSS.

46

VLL

Logic supply voltage.

47

EN

Logic input enable control. When EN = L, all P-channel output drivers are high and all N-

channel output drivers are low.

48

AVSS

Negative driver supply for OUT-PA3, OUT-PB3 and bias circuits. They are also connected

to the IC substrate. They are required to connect to the most negative potential of voltage

supplies.

Center

Pad

AVSS

For the QFN package, the center pad is at AVSS potential. It should be externally connected

to AVSS.
