4 / 36 page 33991 MOTOROLA ANALOG INTEGRATED CIRCUIT DEVICE DATA 4 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 VPWR 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.
