15

RST

Reset. If the master decides to reset the device, or place it into a sleep state, the RST pinisdriventoa logic0. A

logic 0 on the RST pin will force all internal logic to the known default state. This input has an internal active pull-up.

16

Battery Voltage. Power supply.

17-20

GND

Ground. These pins serve as the ground for the source of the low-side output transistors as well as the logic portion

of the device. They also help dissipate heat from the device.

21

SIN1-

H-Bridge Output. This pin is the output of a half bridge, designed to source or sink current. The H-Bridge pins linearly

drive the sine and cosine coils of two separate stepper motors to provide four-quadrant operation.

22

SIN1+

H-Bridge Output. This pin is the output of a half bridge, designed to source or sink current. The H-Bridge pins linearly

drive the sine and cosine coils of two separate stepper motors to provide four-quadrant operation.

23

COS1-

H-Bridge Output. This pin is the output of a half bridge, designed to source or sink current. The H-Bridge pins linearly

drive the sine and cosine coils of two separate stepper motors to provide four-quadrant operation.

24

COS1+

H-Bridge Output. This pin is the output of a half bridge, designed to source or sink current. The H-Bridge pins linearly

drive the sine and cosine coils of two separate stepper motors to provide four-quadrant operation.
