Common ground terminals. In Powerdip and SO packages, these pins are

also used for heat dissipation toward the PCB.

20

Enable of the Bridge A. A LOW logic level applied to this pin switches off

all the power DMOSs of the related bridge.

The Bridge A over current protection open drain is internally connected to

this pin.

16

11

Enable of the Bridge B. A LOW logic level applied to this pin switches off

all the power DMOSs of the related bridge.

The Bridge B over current protection open drain is internally connected to

this pin.

2

Logic inputs of the Bridge B. Provided the ENA signal is HIGH, a HIGH

logic level applied to any of these pins switches on the related high side

power DMOS, while a logic LOW switches on the related low side power

DMOS .

10

Logic inputs of the Bridge B. Provided the ENB signal is HIGH, a HIGH

logic level applied to any of these pins switches on the related high side

power DMOS, while a logic LOW switches on the related low side power

DMOS .
