GND

GND

Signal ground terminals. In PowerDIP and SO

packages, these pins are also used for heat dissipation

toward the PCB.

822

Bridge B output 1.

924

RC pin

RC network pin. A parallel RC network connected

between this pin and ground sets the current controller

OFF-time of the bridge B.

25

Bridge B source pin. This pin must be connected to

power ground through a sensing power resistor.

28

Analog input

Bridge B current controller reference voltage.

Do not leave this pin open or connect to GND.

14

29

Bridge B enable. LOW logic level switches OFF all

Power MOSFETs of bridge B. This pin is also connected

to the collector of the overcurrent and thermal protection

transistor to implement overcurrent protection.

If not used, it has to be connected to +5 V through

a resistor.

Logic input(1)

Bridge A enable. LOW logic level switches OFF all

Power MOSFETs of bridge A. This pin is also connected

to the collector of the overcurrent and thermal protection

transistor to implement overcurrent protection.

If not used, it has to be connected to +5 V through

a resistor.

24

Analog input

Bridge A current controller reference voltage.

Do not leave this pin open or connect to GND.

1. Also connected at the output drain of the overcurrent and thermal protection MOSFET. Therefore, it has to be driven putting

in series a resistor with a value in the range of 2.2 K

 - 180 K, recommended 100 K
