Definition

1

AGND

Analog Ground

Low-current analog signal ground.

2

FS

Fault Status for H-

Bridge

Open drain active Low Fault Status output requiring a pull-up resistor to 5.0 V.

3

IN1

Logic Input Control 1

True logic input control of OUT1 (i.e., IN1 logic High = OUT1 logic High).

4, 5, 16

V

+

Positive Power Supply

Positive supply connections.

6, 7

OUT1

H-Bridge Output 1

Output 1 of H-Bridge.

8, 20

DNC

Do Not Connect

Either do not connect (leave floating) or connect these pins to ground in the application.

They are test mode pins used in manufacturing only.

9–12

PGND

Power Ground

Device high-current power ground.

13

D2

Disable 2

Active Low input used to simultaneously tri-state disable both H-Bridge outputs. When

D2 is logic Low, both outputs are tri-stated.

14, 15

OUT2

H-Bridge Output 2

Output 2 of H-Bridge.

17

CCP

Charge Pump Capacitor External reservoir capacitor connection for internal charge pump capacitor.

18

D1

Disable 1

Active High input used to simultaneously tri-state disable both H-Bridge outputs. When

D1 is logic High, both outputs are tri-stated.

19

IN2

Logic Input Control 2

True logic input control of OUT2 (i.e., IN2 logic High = OUT2 logic High).
