FUNCTIONAL DESCRIPTION
FUNCTIONAL PIN DESCRIPTION
VOLTAGE (VDD)
This SPI and logic power supply input will work with 5.0 V
supplies.
RESET (RST)
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 (VPWR)
Power supply.
H-BRIDGE OUTPUTS 1 (SIN1-, SIN1+, COS1-,
COS1+)
Each of these pins 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 step motors to
provide four-quadrant operation.
