8PGND

Ground

Power ground pins. They must be connected to other

ground pins

SENSEA

Analog input

Phase A current sensing input

SENSEB

Analog input

Phase B current sensing input

OUTA1

Power input

Full-bridge A output 1

OUTA2

Power input

Full-bridge A output 2

OUTB1

Power input

Full-bridge B output 1

AGND

Ground

Analog ground. It must be connected to other ground

pins

Logical input

External switch input pin

DGND

Ground

Digital ground. It must be connected to other ground

pins

SDO

Logical output

Data output pin for serial interface

SDI

Logical input

Data input pin for serial interface

Logical input

Serial interface clock

Logical input

Chip select input pin for serial interface

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

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, it should be connected to VREG

STCK

Logical input

Step-clock input

EPAD

Exposed pad Ground

Exposed pad. It must be connected to other ground

pins
