FUNCTIONAL DESCRIPTION

FUNCTIONAL PIN DESCRIPTION

SERIAL OUTPUT (SO)

This output pin is connected to the SPI Serial Data Input

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 CS pin of the device

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.

POSITIVE POWER SUPPLY (VPWR)

This pin connects to the positive power supply and is the

source input of operational power for the device. The VPWR

pin is a backside surface mount tab of the package.

HIGH-SIDE OUTPUT (HS)

This pin protects high side power output to the load.

Output pins must be connected in parallel for operation.
