Reset. If the master decides to reset the device, or place it into a sleep state, the RST pin is driven to a
logic 0. 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.
Battery Voltage. Power supply.
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.
H-Bridge Output. This is the output pin 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.
