Pin Description

Pin #

Name

Description

1

POSA / POS1A

Logic input control for channel A. When SEL = L, the pin is POSA. When SEL = H, the pin

is POS1A.

2

NEGA / NEG1A

Logic input control for channel A. When SEL = L, the pin is NEGA. When SEL = H, the pin

is NEG1A.

3

HVEN1A / POS2A Logic input control for channel A. When SE L= L, the pin is HVEN1A. When SEL = H, the

pin is POS2A.

4

HVEN2A / NEG2A Logic input control for channel A. When SEL = L, the pin is HVEN2A. When SEL = H, the

pin is NEG2A.

5

CLAMPA

Used with SEL = H. Logic input control for OUT-PA3 and OUT-NA3. Connect to ground when

SEL = L.

6

AV

Supplies analog circuitry portion of the gate driver. Should be at the same potential as

DV

7

AGND

Analog Ground.

8

CLAMPB

Used with SEL = H. Logic input control for OUT-PB3 and OUT-NB3. Connect to ground when

SEL = L.

9

HVEN2B / NEG2B Logic input control for channel B. When SEL = L, the pin is HVEN2B. When SEL = H, the

pin is NEG2B.

10

HVEN1B / POS2B Logic input control for channel B. When SEL = L, the pin is HVEN1B. When SEL = H, the

pin is POS2B.

11

NEGB / NEG1B

Logic input control for channel B. When SEL = L, the pin is NEGB. When SEL = H, the pin

is NEG1B.

12

POSB / POS1B

Logic input control for channel B. When SEL = L, the pin is POSB. When SEL = H, the pin

is POS1B.

13

SEL

Logic input select. See truth tables for SEL = L and SEL = H.

14

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.

15

16

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.

17

OUT-PB3

Output P-Channel gate driver for channel B.

18

DGND

Digital Ground.

19

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

20

OUT-PB2

Output P-Channel gate driver for channel B.

21

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

22

OUT-PB1

Output P-Channel gate driver for channel B.

23

N/C

No connect.

24

OUT-NB1

Output N-Channel gate driver for channel B.

25

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
