6 VS Power supply Motor voltage

3 HVGA1 Power output High-side half-bridge A1 gate driver output.

36 HVGA2 Power output High-side half-bridge A2 gate driver output

17 HVGB1 Power output High-side half-bridge B1 gate driver output

22 HVGB2 Power output High-side half-bridge B2 gate driver output

1 LVGA1 Power output Low-side half-bridge A1 gate driver output

38 LVGA2 Power output Low-side half-bridge A2 gate driver output

19 LVGB1 Power output Low-side half-bridge B1 gate driver output

20 LVGB2 Power output Low-side half-bridge B2 gate driver output

8, 23, 35 PGND Ground Power ground pins. They must be connected to other ground pins.

2 OUTA1 Power input Full bridge A output 1

37 OUTA2 Power input Full bridge A output 2

18 OUTB1 Power input Full bridge B output 1

21 OUTB2 Power input Full bridge B output 2

16 AGND Ground Analog ground. It must be connected to other ground pins.

33 SW Logical input External switch input pin

29 DGND Ground Digital ground. It must be connected to other ground pins

28 SDO Logical output Data output pin for serial interface

26 SDI Logical input Data input pin for serial interface

25 CK Logical input Serial interface clock

24 CS Logical input Chip select input pin for serial interface

30 BUSY

/SYNC Open drain output

By default, the BUSY /SYNC pin is forced low when the device is

performing a command.

The pin can be programmed in order to generate a synchronization

signal.

31 FLAG Open drain output

Status flag pin. An internal open drain transistor can pull the pin to

GND when a programmed alarm condition occurs (step loss, OCD,

thermal pre-warning or shutdown, UVLO, wrong command, non-

performable command).

STBY

RESET

Logical input

Standby and reset pin. LOW logic level puts the device in Standby

mode and reset logic.

If not used, should be connected to V

REG

32 STCK Logical input Step-clock input

EPAD Exposed pad Ground Exposed pad. It must be connected to other ground pins.
