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.
