SENSEB

Power supply

Bridge B source pin. This pin must be connected to power ground

through a sensing power resistor.

17

IN1B

Logic input

Bridge B input 1

18

IN2B

Logic input

Bridge B input 2

19

VREFB

Analog input

Bridge B current controller reference voltage. Do not leave this pin open

or connect to GND.

20

ENB

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 must be connected to +5 V through a resistor.

21

VBOOT

Supply voltage

Bootstrap voltage needed for driving the upper power MOSFETs of both

Bridge A and bridge B.

22, 23

OUT2B

Power output

Bridge B output 2.

26, 27

VSB

Power supply

Bridge B power supply voltage. It must be connected to the supply

voltage together with pin VSA.

34, 35

VSA

Power supply

Bridge A power supply voltage. It must be connected to the supply

voltage together with pin VSB.

38, 39

OUT2A

Power output

Bridge A output 2.

40

VCP

Output

Charge pump oscillator output.

41

ENA

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 transistor to implement overcurrent protection. If not used, it must be

connected to +5 V through a resistor. Thermal protection

VREFA

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 must be driven putting

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

 - 180 k, recommended 100 k.
