SI
Serial Input
This is a command data input terminal connected to the SPI Serial Data Output of the
MCU or to the SO terminal of the previous device of a daisy chain of devices. The input
requires CMOS logic-level signals and incorporates an internal active pull-down.
Device control is facilitated by the input's receiving the MSB first of a serial 8-bit control
command. The MCU ensures data is available upon the falling edge of SCLK. The logic
state of SI present upon the rising edge of SCLK loads that bit command into the
internal command shift register.

V
DD
Digital Drain Voltage
(Power)
This is an external voltage input terminal used to supply power to the SPI circuit. In the
event V
DD
is lost, an internal supply provides power to a portion of the logic, ensuring
limited functionality of the device.
11
SO
Serial Output
This is an output terminal connected to the SPI Serial Data Input terminal of the MCU
or to the SI terminal of the next device of a daisy chain of devices. This output will
remain tri-stated (high impedance OFF condition) so long as the
CS
terminal of the
device is logic HIGH. SO is only active when the
CS
terminal 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.
12
IN1
Serial Input
This input terminal is used to directly control the output HS1. This input has an internal
active pull-down and requires CMOS logic levels. This input may be configured via SPI.
13
GND
Ground
This terminal is the ground for the logic and analog circuitry of the device.
14
V
PWR
Positive Power Supply
This terminal connects to the positive power supply and is the source input of
operational power for the device. The V
PWR
terminal is a backside surface mount tab
of the package.
15
HS1
High-Side Output 1
Protected 4.0 m
high-side power output to the load.
16
HS0
High-Side Output 0
Protected 4.0 m
high-side power output to the load.
