SERIAL OUTPUT (SO)
pin of the MCU or to the SI pin of the next device in a daisy
chain of devices. This output will remain tri-stated (high-
impedance OFF condition) so long as the
is logic HIGH. SO is only active when the CS pin of the device
is asserted logic LOW. The generated SO output signals are
CMOS logic levels. SO output data is available on the falling
edge of SCLK and transitions immediately on the rising edge
of SCLK.

FUNCTIONAL DESCRIPTION
FUNCTIONAL PIN DESCRIPTION
This output pin is connected to the SPI Serial Data Input
CS
pin of the device
POSITIVE POWER SUPPLY (VPWR)
source input of operational power for the device. The VPWR
pin is a backside surface mount tab of the package.
HIGH-SIDE OUTPUT (HS)
Output pins must be connected in parallel for operation.
This pin connects to the positive power supply and is the
This pin protects high side power output to the load.
