Each pin is the output pin of a half bridge, designed to source or sink
current.
These pins serve as the ground for the source of the low-side output
transistors as well as the logic portion of the device.
This pin is connected to a chip select output of a LSI IC.
This pin is connected to the SCLK pin of the master device and acts
as a bit clock for the SPI port.
This pin is connected to the SPI Serial Data Input pin of the master
device or to the SI pin of the next device in a daisy chain.
This pin is connected to the SPI Serial Data Output pin of the master
device from which it receives output command data.
This is a multiplexed output pin for the non-driven coil, during a Return
to Zero (RTZ) event.
This SPI and logic power supply input will work with 5.0 V supplies.
This input has an internal active pull-up.
Power supply.
Each of these pins is the output pin of a half bridge, designed to
source or sink current.
